AG310 the well known guru Chris

Towle explains the philosophy of Zone

2 apparatus and how extra low voltage

Ex nA certified instrumentation may be

safely installed in these low risk areas.

Current ATEX and IECEx standards

are discussed together with installation

practice, constructional requirements,

documentation and routine inspection.

Of particular interest is the use of Ex nA

certified apparatus with instruments using

other protection techniques. Chris

shows how an Ex nA loop powered

indicator in Zone 2 may be used to

monitor the output from a Zone 1 Ex d

transmitter, simplifying installation and

reducing cost.

Although using BEKA 4/20mA loop

powered indicators to illustrate

recommended installation practice, the

examples apply to most low voltage Ex nA

apparatus.

“No sanctions and a continuation of Iran’s uranium enrichment programme will lead to a direct threat of nuclear attack on Israel by an unstable and dangerous regime which believes in martyrdom so wouldn’t care about the inevitable mutual destruction.”

“Under these circumstances, Israel would be forced to launch a large-scale pre-emptive attack on Iran’s nuclear facilities. In this case, all we can really do is pray,” said Dr Slowe - who is MD of Projects Abroad the world’s largest volunteering organisation who support philanthropic projects worldwide.

The US – supported by the EU – believe that cutting the flow of oil revenue to the Iranian regime will force them back to the negotiating table after the last talks failed in 2010 when the UN Security Council demanded a halt to uranium enrichment in Iran.

President Obama and the Israelis have not dismissed the possibility of attacking Iran if the issue is not resolved. In return, Iran is threatening to attack US bases in the Gulf and close the Strait of Hormuz.

“The West was far to slow putting oil sanctions in place. We’ll all benefit when the theocratic dictatorship in Iran is overthrown, and oil sanctions – combined with the current policy of carefully targeted bombings and assassinations – will pile on the pressure,” said Dr Slowe – who was a financial advisor to the Blair government.

“It’s a tragedy that ordinary Iranians will suffer too but, in the end, sanctions will help to bring about the conditions for a Persian Spring which will be even more beautiful than the Arab Spring. India and China, who buy lots of Iranian oil, ought to join in the sanctions but they probably won’t until they actually see that the violent and unstable alternative hits them where it hurts – right in the treasury.”

The Iranian Regime Had Announced That It Would Ban Oil Exports To

Europe Before The Eu Sanctions Could Come Into Force.

US led sanctions are starting to have an effect in Iran and the pain will inevitably impact

the hardest on ordinary people but according to Dr Peter Slowe – vice-president of the

Labour Finance and Industry Group – we have to ask ourselves what would be the cost

of not imposing sanctions.

Climate Center To Offer Welding Gases From Its Nationwide Network Of BranchesIn a significant addition to its range, Climate Center has announced that it is to supply welding gases to the refrigeration and air conditioning trade via its nationwide network of branches.

The Braze-A-Gas package includes oxygen and acetylene cylinders, flame torches and accessories to enable engineers to braze a full range of pipe work and system components.

“It means contractors can now source everything they need for a project from a single supplier, rather than having to go to a specialist supplier for welding and brazing gases. It will save people time and money and make life more convenient,” says Robert Franklin, who heads up Climate Center’s cooling business.

Use of brazing has increased significantly in the refrigeration and air conditioning sector recently due to the trend away from use of traditional flare connections and their replacement with fully-brazed, sealed systems, in order to minimise refrigerant leakage.

Oxy-acetylene is the preferred medium for brazing as it delivers the hottest flame (3500deg C) of all commonly used fuel gases. This is important in ensuring full penetration of filler metal into the brazed joint to create a strong, refrigerant-tight seal.

While other types of brazing fuel are only suitable for use with smaller pipe work and components, oxy-acetylene can be used with larger diameter pipe, bigger components such as vibration eliminators and a range of materials, including copper and steel.

Oxygen cylinders are colour-coded with a distinctive white shoulder, and acetylene cylinders are painted the traditional maroon with a reflective stripe, to increase visibility in low light conditions.

Accessories available in Climate Center’s Gas-Arc range include gauges, safety goggles and flame torches.

Oxy-acetylene welding supplies will be added to Pipe Center’s offering in the near future.

It is generally agreed that despite

concerns about safety post-Fukushima,

nuclear needs to play an important role

in the UK’s energy future to guarantee

security in an ever more uncertain (and

expensive) energy landscape. Today’s

news that the two European behemoths

of RWE Npower and E.ON will not

provide any investment in nuclear plants

going forward due to costs of shutting

reactors down in Germany and an

uncertain economic climate may be

music to the ears of renewable energy

campaigners but could shift the pressure

onto gas supplies to plug the looming

supply gap. While the government may

have pre-empted this with a vision

to invest in gas supplies around the

Shetland Isles, this is will most likely

not be sufficient to meet the UK’s future

needs.

Two nuclear consortia remain with plans

on the table – NuGen (GDF Suez and

Iberdrola), which is planning to build a

plant in West Cumbria, and Centrica

and EDF with joint plans to build a plant

at Hinkley Point. If these consortia also

shelve their plans, the UK will be even

more reliant on gas imports, as gas fired

generation will be required to shoulder

even more responsibility to supply

baseload power.

No Nuclear Investment Threatens the UK’s Energy Security

Today (29/03/12) RWE Npower

and E.ON have announced a

halt to any investment in new

nuclear generating capacity in

the UK with fears that the UK

could become a lame duck over

reliant on costly imports.

New Draeger Flame Detector Offers False Alarm Immunity In Rail Or Road Applications

Designed for standalone operation, the new Draeger Flame 3000 is an explosion-proof Flame Detector.

Ideal for use in fuel transport terminals, it is not affected by sunlight and, in traffic tunnels, is impervious

to headlights, flashing lights and hot engines. This advanced image processing detector is also suitable

for use in rail loading areas as the sensitivity remains unaffected by moving reflections and, in addition,

an automatic shutdown system can be used to extinguish all fuel type fires. Based on the proven

technology of the Draeger Flame 5000, this advanced image processing detector offers a reliable

solution to flame detection and false alarm immunity.

Believed to offer the greatest coverage area of any flame detector on the market, the Draeger Flame 3000 has a rectangular, pyramid shaped field of view. Representing a radial projection of the sensing element, this extends to 110° horizontal and 80° vertical, with an increased range of 60 metres to an n-Helptane 0.1m2 pan fire. Housed within a single unit and approved to ATEX, IECEx and FM, the detector combines digital signal processing with software algorithms to process and interpret the characteristics of a flame. These image processing algorithms are so discriminating that the detector is immune to false alarms. Requiring only one detection sensitivity setting, the Flame 3000 is unaffected by the background radiation found in many industrial environments. Superior false alarm immunity is also possible against common sources of unwanted alarms such as hot processes, hot work, hot CO2 emissions and flare reflections. Easy to install with a stainless steel mounting bracket that can be rotated to ensure optimum positioning in relation to the potential fire source, it is also flexible in use. In addition to standalone operation, the Flame 3000 can be integrated with a control system or fire panel, via 0 to 20mA or relay outputs, to provide both fault and fire signalling. Personnel in close proximity to the detector can quickly confirm the system status via a tri-colour LED. Green indicates normal operation, yellow highlights a fault and red warns of the presence of flame.Functionality testing can be a complicated and difficult process. An advanced optical verification test using the Draeger FS-5000 ensures that the unit remains ready to perform as and when it is needed. Able to activate the Flame 3000 from a distance of up to 8m, this Flame Simulator eliminates the need for scaffolding or ladders when carrying out functional testing and, as a result, further reduces maintenance costs. Developed for use in extreme offshore environmental conditions, the FS-5000 electronics are secured in an enclosure specifically designed for Zone 1 hazardous areas.Draeger Fire and Gas Detection Systems offers products, services and system solutions for all encompassing toxic, flammable and oxygen detection, flame detection and design, build, commission and maintenance of fire and gas detection systems for protection of personnel and assets.

The international oil company in Azerbaijan has ordered an explosion proof processed water pump unit from UK pump manufacturer PumpSets Ltd for use in a Zone 2 hazardous area. The unit includes an APEX pump which can pump water containing traces of oil at a flow rate of 350m3/ hr at 60m head.

To power the pump, PumpSets ordered a radiator to flywheel explosion proof diesel engine package from Pyroban which was delivered fully built onto a skid frame, tested and certified to ATEX 94/9/EC and the Machinery Directive. The 167bhp (1800rpm) prime mover, a Perkins 1006.6TW diesel engine, required a complete explosion proof modification from Pyroban to ensure that it could not be the source of ignition from hot surfaces, engine over-speed or gas ingestion. The Pyroban explosion proof diesel engine package included an exhaust gas cooler, an SVG valve to prevent engine overspeed and flame from the inlet, flame and spark arrestors, a water-cooled turbocharger and other safety critical components. The Pyroban explosion proof

package also included a marine radiator designed and manufactured by Pyroban Group Company, Broadland Radiators.

Pyroban manufactured the complete explosion proof package at its works in West Sussex in the UK and the unit is fully certified to Category 3G T3 IIB ATEX 94/9/EC as a component, based on the standard EN1834-1:2000. With Pyroban’s support, PumpSets were able to easily supply the complete pumping unit with one ATEX 94/9/EC certificate after final testing.

Diesel engines are widely used in the oil and gas industry, upstream and downstream, where there is a risk of hydrocarbon release. Today, more companies are ensuring the safety of their people, the environment, their brand and production levels, by insisting on full explosion protection for diesel engines operating in hazardous areas.

Pyroban is an international group of companies providing a wide range of explosion protection safety services and products to the oil and gas sector, including hazardous area consulting, training, components, mobile equipment conversion and engineering support.

Crowcon Showing The Latest Developments In Gas Detection Technology At Health & Safety Expo 2012

Among the new products on show will be the Gas-Pro portable confined space entry (CSE) gas detector. Specifically designed for CSE work, the Gas-Pro has application-driven features that include a top-mount display, internal pump, detection of up to five gases simultaneously, and a tri-colour status indicator.

Crowcon will also be showing a number of other new gas detection products, including an un-powered gas test unit for the Tetra 3 portable gas detector, which utilises the functionality of the Tetra 3 to carry out a simple and fast gas test in a matter of minutes.

In addition, the IRmax infrared (IR) flammable gas detector will be on display. Unlike conventional IR gas detectors, IRmax does not use heaters to prevent condensation on windows and mirrors. Instead, its optical components are treated with a highly durable hydrophobic coating called STAY-CLIR that completely prevents signal faults due to condensation. The IRmax is also available with the HART

(Highway Addressable Remote Transducer) Communication Protocol, a global standard for sending and receiving digital information across analog wires between smart devices and control or monitoring systems

All these new products, as well as Crowcon’s existing range of state-of-the-art gas detection products, can be found in Hall 1, stand number F80. Crowcon’s experts will also be on hand to answer any gas-safety related questions.

A number of different brands of dryer have been tried and tested on site with limited success. Some dryers actually failed in less than 6 months.

BEKO TECHNOLOGIES looked at the PH value of the condensate and the acidic ambient conditions. From this a tailor-made DRYPOINT RA 600 solution was offered, where all the internal copper piping and condensate discharge points of the dryer were coated with a special anti-corrosion treatment. The first RA dryer sold to KP Foods has been installed on site now for nearly 4 years without a single failure. This was a major factor in the choice for the new dryers for the Hoops compressor room location.

Pressure drop was also a major factor as well as pipe work distribution. With this in mind BEKO were invited to tender for the whole turnkey project which included removing all the old equipment, supply and installation of new dryers, filters and pipework. BEKO

successfully won the order for the complete turnkey project and in conjunction with Direct Air and Pipework of Coventry the whole installation was carried out in less than 48 hours. The installation included a complete new 6” manifold, 4” drops into the 2 x DRYPOINT RA 600 dryers and 2 x Flanged filters. Timing was essential as the compressed air went off at 2pm on a Saturday and had to be installed and running by 8pm on a Sunday. The installation was successfully carried out on time. KP Foods are now reaping the rewards in energy reduction of very low pressure drop and a constant dewpoint throughout their factory with the added reliability of the BEKO DRYPOINT RA range.

An explosion at a chemical plant in Germany killed at least one person and left two others injured Saturday. A tank exploded at the Evonik Degussa plant in the western city of Marl and started a blaze, which about 100 fire fighters managed to bring under control. The injured man was flown to hospital, while a third person suffered only light injuries and was discharged earlier today. Marl, a city of 87,000 in the Ruhr industrial heartland, is an important chemical industry hub. Its chemical park is among Europe’s biggest, with 30 firms employing about 10,000 workers producing more than 4,000 products.

The blast – whose cause was not immediately known – was triggered in a tank containing substances used in the production of plastic parts in the auto industry, as well as in electronics and cosmetics.

A column of smoke rose 100 meters high in the wake of the explosion, but initial checks by environmental authorities don’t indicate there’s any danger to health.

Borders & Southern Makes ‘Significant’ Gas Discovery Off Falkland Islands

Explorer Borders & Southern has discovered

“significant” gas condensate reserves south

of the Falkland Islands, opening up a new

and controversial oil and gas basin.

Shares in the Aim-listed company fell 32pc, to 89.5p, however, having

almost doubled in value last week, amid rumours the company had

struck crude oil. Gas condensate - a lighter, petrol-like substance - could

be more challenging to extract commercially, analysts said, and data on

the scale of the discovery are, at this stage, vague.

Borders & Southern said it would now conduct tests on samples of fluids

recovered from the reservoir. “It is too early to give an accurate resource

estimate,” it said, but the rock was “likely to contain significant volumes”.

Its chief executive, Howard Obee, said: “We’re delighted to have made

a discovery with the company’s first exploration well and to have

opened up a new hydrocarbon basin.

“There is clearly a lot of work ahead of us to understand the size and

value of the discovery, but it is a great start and the potential of the

basin is exciting.”

Oil was found to the north of the Falklands two years ago by

Rockhopper, which is now seeking to develop its assets. However,

this is the first discovery of resources to the south of the disputed

islands.

“There is clearly a lot of work ahead of us to understand the size and value of the discovery, but it is a great start and the potential of the basin is exciting.”

ATEX compliance consists of two European directives concerning what

equipment is required for use in an explosive atmosphere, and since

2003 all European organisations must protect employees from such

atmospheres. Verlinde has been designing products for safe use in such

environments for some time now and increasing demand from the UK

market needed a supplier and expert ‘on the ground’, which led the

French giant to turn to Alpha Lifting Services. Commenting on Alpha’s

selection, business development manager for Verlinde, Simon Rothechild,

said: “Alpha Lifting Services has over 20 years experience in advising

customers on explosion proof products, so it was a simple decision to

appoint them as the agent for Verlinde incorporating explosion proof

equipment. This is a growing market in the UK and we wish them well

with.”

Verlinde’s most popular products in this field are the Eurolift, Eurochain

and Eurobloc products, which remain identical in performance to the

standard cranes of this type but are fully EX (ATEX certified) explosion

proof. They are perfect for offshore platforms, but as EX certification

is not a standard feature, a UK based agent was required who would

understand the needs of those working in these sectors and be able to

recommend the appropriate cranes and hoists.

While ATEX products are often perceived as products for the

petrochemical industry, the fact is many materials in dust form (if they

oxidise) can generate a potentially explosive mix. While coal is the

well-known example, other, seemingly more mundane substances can be

equally dangerous. These include flour, sugar and even powdered milk –

which puts ATEX cranes high on the menu for the food industry too.

“The market for explosion proof products is growing and in some ways

doing much better than the market for standard lifting equipment,” said

Thomas Descamps, managing director of Verlinde. “Verlinde explosion

proof products are set apart by the use of spark proof materials (such as

bronze) and by having units sealed to protect them from flammable

gasses or dusts that may be present in hazardous environments and

we welcome having the expertise of a company like Alpha on board

with us in this critical area.”

Alpha Managing Director, Raymond Marks, commented: “We have

been supplying Verlinde products for some time now, but we are

seeing increasing demand for our expertise in the field of ATEX

products,” he explained. “It is nice to have our expertise formally

recognised by Verlinde and with all the projects that are going on at

the moment, 2012 looks set to be a big year for both companies.”

Devon based Alpha Lifting services reports

Pumps & Valves

Clariant Produkte (Deutschland) produces and processes, among other things, synthetic and natural waxes at their Gersthofen site in Bavaria. Whilst the Synthetic waxes are used in printing inks, paint systems and textiles for coating citrus fruits, the natural montan waxes are mainly for the care product sector as they improve scuff resistance, increase water repellence, and impart high gloss. They are obtained by solvent extraction of certain types of lignite or brown coal, commercially viable deposits of which exist in only a few locations, including Amsdorf, also in Germany.

Franz Kovanetz, Production Engineer at Clariant, explained his process requirements, “Montan wax is recovered from bitumen-containing lignite and processed in several stages to obtain the end product. We have operating conditions here under which some pump designs would fail very quickly!”

“Firstly, we need pumps which can convey a foaming, corrosive medium at a pressure of over 4 bar. Centrifugal pumps frequently fail in this task; if the media starts to foam, conventional centrifugal pumps cavitate, causing damaging vibrations. In addition, as we are dealing with molten wax, the pumps must be heatable to run at temperatures of up to 130°C with heating provided by steam at 145°C. They must also be able to handle varying volumes, from between 300 and 2,000 litres per hour.”

“Finally, in the process stage of oxidation, pumps have to convey on the one hand, the oxidant itself, and on the other hand, the oxidation product still contaminated with oxidant. In this step of the process, legislation demands the use of hermetically tight pumps. In the past, all conventional magnetic drive pumps caused problems in this application. That meant shorter service lives due to sedimentation and damage due to cavitation.”

These challenging requirements had created severe problems for the plant engineers as he continued, “For a long time there was not one single pump manufacturer who could offer a corrosion-resistant centrifugal pump with this broad range of flow rates - 2000 l/h was not the problem, but rather the low flow rate of 300 l/h. Some manufacturers even declined to offer, given the required pressure of over 4 bar. The centrifugal pumps with mechanical seals available 20 years ago had a service life of between one day and two weeks – a dream for every pump manufacturer, but a nightmare for ourselves!”

Franz Kovanetz and his team finally achieved a service life of around two years using a specially installed mechanical seal to comply with the challenge of statutory demands regarding freedom from leaks.

At that time, they also tried out the standard process pumps of the MNK series from Richter Pumps, but even these very robust pumps did not have a satisfactory service life for this application owing to the extreme cavitation.

The breakthrough was only achieved by using Richter’s MPB peripheral pumps which are specially tailored to the delivery of low flow rates at high delivery heads - a range not economically covered by standard centrifugal pumps. The pumps are hermetically sealed and have a magnetic power coupling which equates to no seals and virtually maintenance-free operation. Varying volumes can be coped with efficiently by means of frequency control.

Peripheral pumps, also known as regenerative or regenerative turbine pumps, are designed for relatively low capacities which require pumping to high heads. Their impeller has short vanes at the periphery which pass through an annular channel. The fluid enters between two impeller vanes and is set into a circular motion - this adds energy to the fluid particles which travel in a spiral-like path from the inlet to the outlet. Each set of vanes continuously adds energy to the fluid particles.

Peripheral pumps are more efficient at these low flow, high head conditions than centrifugal pumps, they also require much less NPSHA (Net Positive Suction Head Available) than an equivalent centrifugal pump. Of particular importance, they can also handle liquids with up to 20% entrained gases.

The design of a peripheral pump is specially geared to conveying fairly small volumes to very large heads - operating conditions which frame-mounted pumps do not cover economically. The Richter MPB pump is self-priming up to approximately 6m (water @ 20°C), conveys volumes between 0.1 and 5 m³/h and achieves delivery heads of up to 100 m. It covers a temperature range from -60 to 150°C and operates from a vacuum (at standstill) up to 16 bar, depending on the accessories. It is hermetically tight and has a magnetic drive rating of 6 kW at 2900 rpm or 7.2 kW at 3500 rpm on request. Thanks to the choice of materials (PFA/PTFE, SSiC), the MPB peripheral pump virtually has universal corrosion resistance and can handle media with a gas content of up to 30% by volume. The reduced life cycle costs of the peripheral pumps give Clariant two major advantages as Franz Kovanetz explained, “Firstly, we have

Richter Peripheral Pumps Master Wax ProductionWhilst the properties of Montan wax, also

known as lignite wax or OP wax, make it a

superb raw material for the manufacture of

car and shoe polishes and as a lubricant

for moulding paper and plastics, these

same properties present unique challenges

for engineers who wish to convey the wax

within a process.

Above: The MPB peripheral pumps run at temperatures of up to 130°C; heating is provided by steam at 145°C.


a considerably longer service life and the maintenance costs are substantially lower. Given the expected service life of four years, we are assuming a cost advantage of several thousand euros for each pump.”

“Secondly, and equally important, is that the plant has to cope with fewer disruptions. Every interruption in a continuous process always means affecting product quality. Even if one continuous plant is run constantly, the product quality remains at a high level without fluctuations. Moreover, all pumps are integrated into the process control system – for example, there is also an automatic routine for cleaning the pump.”

The long service life with low maintenance costs is mainly due to the design of the impeller seal - the patented sealing lips integrated in the impeller provide the sealing, which is crucial for high efficiency, between the impeller and the housing wall of the silicon carbide ring channel. The sliding surfaces of the ring channel are polished to a high-gloss finish – which allows the sliding of the impeller sealing lips producing minimum friction and minimum wear.

Another crucial advantage is the simple and quick assembly: the resilient sealing lips dispense with the need for adjustment of the impeller ring channel to an accuracy of 0.1 mm. Such close but hydraulically important gaps frequently result in premature wear in conventional peripheral pumps – especially with fluctuating temperatures – and require a large amount of time for their precise assembly and maintenance. However, the sealing lips of the Richter MPB impeller compensate for the dimensional changes caused by thermal action.

This is particularly important for Clariant: both the oxidant and the oxidation product still containing acid have temperatures of well over 100°C. “The Richter peripheral pump offers very good temperature

resistance and it easily withstands even very small temperature shock.” commented Franz Kovanetz.

Today, Richter peripheral pumps are the standard at Clariant for conveying highly oxidising substances and other corrosive media. These pumps are proving successful and have the longest service lives thanks to special technical details: An MPB pump installed for test purposes in 2004 is also still running without any problems in 2011.

Richter Pumps are available in the UK exclusively through Billingham-based Tomlinson Hall Ltd who were appointed sole UK distributor this year. The appointment coincided with Tomlinson Hall’s success at this year’s Pump Industry Awards where the company was named Britain’s Pump Distributor of the Year for the second consecutive year.

Renowned for their innovative magnetic drive and mechanically sealed plastic-lined pumps for difficult corrosive and hazardous fluids, Richter pumps have now become the standard within the European chemical, petrochemical and pharmaceutical industries and other sectors where corrosive, hazardous, contaminated, pure and ultrapure media are used.

Colin Simpson, Sales Director at Tomlinson Hall, added, “Richter has set the bar for PFA-lined magnetic drive and mechanically sealed pumps for decades, and we are delighted to have been chosen to help re-establish the brand here. The appointment is also further testament to our own commitment to providing the very best global pump products to industry.”

“Richter’s innovative approach to its products, coupled with its reliability, environmental protection and low maintenance requirements has ensured the brand remains an excellent investment for buyers. Their products vastly outperform the competition on a number of operational levels throughout the world, including those produced here in the UK. This year will also see the global launch of their new range of PFA-lined and mechanically sealed pumps so it’s exciting times for both organisations.”

Tomlinson Hall is a family owned business based on Teesside

specialising in the distribution of pumps, power transmission equipment

and engineering supplies. In March the company was named as

Britain’s Pump Distributor of the Year for the third consecutive year in

this year’s prestigious Pump Industry Awards.

Understanding ATEX MillingBy Colin Ellis (Managing Director, Hanningfield)

Introduction to ATEXPast legislation to control explosive atmospheres

has only been concerned with electrical equipment.

The current ATEX directives now include hazards from

mechanical sources, such as mills. A seized bearing or

mechanical failure causing excessive heat generation is as

likely a cause of explosion as an electrical fault and is now

considered of equal importance in the design and use of

size reduction equipment for powder processing.

ATEX Standards

There are currently two European directives in existence, 94/9/EC

which is principally for manufacturers and another for operators of

the equipment 99/92/EC. 94/9 EC is implemented in the UK by the

Equipment and Protective Systems intended for use in Potentially

Explosive Atmospheres Regulations 1996 (EPS Regulations). 99/92/EC

is implemented in the UK by the Dangerous Substances and Explosive

Atmospheres Regulations 2002 (DSEAR).

Both EU directives have been in place for several years, 94/9/EC since

1st July 2003 and the provisions of 99/92/EC extended to 1st July 2006.

Complying with ATEX

To comply with these standards a number of precautions must be

taken to eliminate any risk potential. The first step is to carry out a risk

analysis (Ignition Hazard Assessment) on the product to be milled and

the environment in which the size reduction process will take place. This

assessment will determine type of hazardous zoning inside and outside

the mill and should be carried out by the user of the equipment.

Using the information provided, the mill supplier can then design the

equipment to meet the appropriate ATEX Directive measures. The

mill supplier is also responsible to advise the user of any precautions

necessary to operate the mill safely.

ATEX Categorisation

In addition to the consideration of mechanical machine features, further

categorisation is divided between gas and dust risks. The levels of risk

fall into various zones; 0, 1 or 2 for gas, 20, 21 and 22 for dust. There are

also individual equipment categories; 1, 2 and 3 (see table).

To comply with each level of risk various accessories may be fitted

to the machine such as temperature sensors, nitrogen purging

systems, earth-bonding and anti-static castors. ATEX rated electrical

equipment and accessories are also used including motors, safety

switches and control panels.

Equipment Location

It is important to ensure that when positioning equipment that either

contains an explosive atmosphere, or is situated in an ATEX zoned

environment that the location is matched with the equipment in use.

If the equipment is situated in an ATEX zoned area then the external

features of the mill must comply with the ATEX provisions according

to the zone. Special care should be taken relating to the effect on

the surrounding area and also affects resulting from the surrounding

area.

Manufacturer’s Responsibilities

The mill manufacturer has a responsibility to the customer to provide

correctly designed equipment and the user or purchaser has a legal

right to expect an acceptable level of safety from the equipment

supplier. It is therefore or paramount importance to ensure the user

has adequate information on the limitations of use and operating

parameters. Adequate instructions of the limitations of use and

operation must be supplied along with training where required to

ensure equipment is use safely and as intended.

The ATEX Compliant Hanningfield Mill

With many years experience of designing and supplying explosion

category milling equipment, the Hanningfield UNI-MILL provides

the ideal solution to meet ATEX legislation directives. Special

features such as continuous earth design, temperature monitoring

and nitrogen purging ensure appropriate compliance measures

are in place for every machine supplied to meet the level of hazard

specified.

Although ATEX legislation appears to be quite complex, with proper

consultation between user and supplier a safe system that meets the

requirements of ATEX can be fully complied with.


NEW PRODUCT

INDUSTRIAL ACCELEROMETER

The sensing element of the HT602D01 provides nominal sensitivity

of 100mV/g over a frequency range of 0.5 to 8000Hz (±3dB). Unlike

many sensors on the market, PCB Piezotronics’ HT602D01 uses a

shear sensing element to minimise the base bending and thermal

transient effects that occur in conventional compression mode

accelerometers. This renders the HT602D01 accelerometer far less

sensitive to unwanted electrical output and leads to more accurate

measurement of the actual vibration event.

Featuring a 2-pin MIL connector, the sensor can be used as a drop-

in replacement for many existing accelerometers but offers the higher

temperature range compared with conventional industrial devices.

It is priced very competitively against charge mode equivalents and

possesses a number of other features that assist in making vibration

measurements

easier. These include

a 360° swivel mount

that allows for easy

cable orientation

the restrictions of

cable bend radius;

hermetically sealed

cables to eliminate

the restrictions of lower cost polyurethane cables in the presence of acid

fumes; and case isolated to prevent ground loops.

All standard PCB sensors and products are supplied with a two-year

warranty and the company also offers to all customers, at no charge,

24-hour emergency telephone support. This service makes product and

application support available to customers and end-users, day or night,

seven days per week.

PCB Piezotronics Introduces New High Temperature Icp® Industrial Accelerometer

There are many examples of harsh shock and vibration environments:

off-road vehicles, airborne avionics and mining equipment. There are

also some less obvious examples such as pumps and refrigeration

plant, where the vibration is less extreme but persists over many years.

Of course, characteristics will vary from application to application but

generally all environments with vibration or shock can present significant

problems for electrical control systems, particularly position and speed

sensors.

The following 10 simple rules should help design engineers select

position or speed sensors that won’t fail once installed in the field:

1. Use non-contact sensors

Potentiometers are by far the most common form of position sensor

but are generally not suitable for environments with either extreme or

prolonged vibration. This is because a potentiometer’s sliding contacts

wear and so they have a finite lifetime. If we consider a potentiometer

with a lifetime of 1 million cycles, for example, this is likely to be fine

for a benign application which cycles perhaps 100 times per day

because this equates to 10,000 days (or 27 years). However, place

the same potentiometer in an application which is vibrating at 20Hz

(as shown in Figure 1) such as an engine or a pump, and the same

potentiometer is likely to fail in less than a day. This is because the

potentiometer’s contacts will see each vibration as a cycle on a

microscopic scale. If the potentiometer is normally positioned at a

particular point, the wear effect is accelerated and the potentiometer

is likely to fail even more quickly.

2. Damp the sensor electrical output

By definition, the position or speed being measured is likely to

be changing at the vibrating frequency (or some function of the

frequency). A sensor with undamped electronics will output the

measured position and so its output will appear to bounce along

at the vibration frequency. However, if the sensor is damped, the

sensor’s output becomes the average of its measured position. In

some sensors the length of time over which the output is averaged

can be varied – from a fraction of a second or many seconds – to

suit the application.

If a switch or solenoid is to be activated at some point in the

measurement cycle (e.g. a pump switch when a tank is full) then

it may be that the switching point is made repeatedly over a short

period due to the cyclic nature of the vibration. This will cause the

switch or solenoid to open or close rapidly, in turn causing rapid

start-stop of the host system. This can be solved by either damping

Selecting Position Sensors In High Vibration Environments – The Do’s And Don’ts

Machines that are subject to harsh or

prolonged vibration present challenges for

many components – none more so than

position and speed sensors. In this article,

Mark Howard of Zettlex, lists 10 simple

rules for design engineers when selecting

position and speed sensors that must cope

with shock or vibration.

Figure 1 – Potentiometers are generally not suitable

for harsh vibration applications


the sensor or by introducing some hysteresis, which will only allow it

to switch after a set time.

3. Measure position or speed directly not indirectly

If position or speed is to be measured in a vibrating system, it is

likely that different components within the system will be vibrating

at various frequencies and amplitudes. Accordingly, it is more

important in vibrating environments to measure the position of the

actual elements whose position or speed is to be measured directly.

This is opposed to measuring position indirectly – say at the end of

a gear train or multi-link mechanism. Without direct measurement,

measurement accuracy will be degraded.

4. Avoid glass scales for optical sensors

Optical position sensors often use a glass scale through which they

shine and measure their light path. In benign environments most

optical sensors will perform satisfactorily – provided that there is no

foreign matter to interfere with the optical path. However, any glass

scale is susceptible to fracture in environments with heavy shock or

vibration. Of course this results in catastrophic failure of the optical

sensor, with little or no warning.

5. Minimise the weight of the sensors

An often overlooked phenomenon is that damage imparted to

sensors is usually not directly due to the vibration itself but rather

as a result of the momentum of the sensor’s own components.

Minimising weight will minimise momentum and hence minimises

the potential for damage. Lightweight sensors are generally less

susceptible in harsh vibration environments.

6. Use heavy duty connectors - or preferably no connectors

The single largest cause of electrical failure in hash vibration

environments is cables and connectors. Harsh vibration

environments are no place for the flimsy connectors normally

used on consumer electronics. Instead, connectors should be

heavy duty – such as military standard 38999 (shell types) – or at

least include jackscrews to bind the connector’s male and female

elements. If possible, connectors should be eradicated and electrical

interconnections made by direct wiring or flying leads.

7. Potting and encapsulant

An excellent way to mitigate problems due to vibration is to pot

sensors and cables into position. There are a wide variety of 2-part

epoxies used for electronic encapsulation and these are an excellent

method of securing position sensors into the host equipment. This has

added advantages of providing a barrier against contaminants and

improving heat dissipation at elevated temperatures.

8. Stress relieve connecting wires

Wires and cables tend to be forgotten in stress and vibration analyses but

a moving cable is a sure way to generate problems from conductors or

electrical joints cracking due to fatigue. Potting is the preferred method of

eradicating such problems but alternatives include cable wraps, potting

or tightly fitting conduit.

9. Lock any fasteners

This may seem an obvious step but nevertheless it is one that is often

forgotten. Fasteners that secure position sensors should be bonded into

position with thread lock or, preferably, an anti-rotation fastener such as

a tab washer to prevent hex-headed screws from turning and becoming

loose.

10. Use caution with magnetic sensors

If a magnetic sensor is to be used then extreme care should be exercised

in its selection. Firstly, modern rare earth magnets (notably NdFeB types)

are extremely brittle and subject to catastrophic failure if subject to shock.

Magnetic reed switches are prone to fatigue over prolonged periods

where the vibration causes the magnetic switching vane to vibrate and

hence fatigue quickly. Magnetostrictive sensors rely on delicate and

precise location of (easily damaged) amorphous crystal ribbons in wave

guides. The fixture of the ribbon in the wave guide is susceptible under

conditions of either shock or vibration.
