It is important that sensors are located in positions determined in consultation with those who have specialised knowledge of the plant or installation and of the principles of gas dispersion. Reference should also be made to those responsible for the engineering layout and topology of the plant as they will be most familiar with the nature of the potential dangers and the most likely sources of gas release.

It is also important to recognise that the characteristics of the gas source can be influenced by many factors; including the relative density or buoyancy of the gas, the pressure at the point of release, the ambient temperature and the ventilation of the site.

Sensor coverage cannot be simply expressed in terms of ‘number per unit area’. Sensors need to be sited where they are capable of monitoring those parts of a plant where gas may accumulate or when a source of gas release is expected to occur. This way the earliest possible warning of a gas release can be given to initiate shutdown functions, alarm functions or safe evacuation of the premises.

5.3 System Integrity

If a gas monitoring system should fail for any reason, it is important that the system is capable of immediately alerting operational staff to this fact. The sensor will indicate a system failure or mechanical defect and this information can be utilised to initiate a warning alarm. It is good practice to provide emergency facilities to protect against the loss of the mains power supply. Standby batteries can be incorporated with automatic changeover facilities, so guaranteeing continued operation of the pressure sensing system even in the event of a plant breakdown as a result of a power supply failure. Certainly, in critical plants, duplication or triplication of sensors is recommended.

The Trolex TX9042 or TX9044 Programmable Sensor Controller can be programmed to operate with sensors in the multiple voting mode.

5.4 Sensor Management

A very important part of an efficient gas monitoring system is the training of plant personnel in operation and maintenance of the sensors and the complete monitoring system. Training facilities can be provided by qualified Trolex application engineers.

Once a sensor installation is complete, the sensor locations and types should be formally recorded and a planned test and maintenance procedure instituted.

5.6 Hazardous Areas

Do not disassemble the sensor whilst in the hazardous area or use a sensor that has a damaged housing in the hazardous area.

5.7 Evacuation

If a dangerous level of gas concentration is detected by the instrument, leave the area immediately.

5.8 Operating Life

Electrochemical cells contain an electrolyte that is gradually consumed during use.

The average life is about two years, dependent upon the duty cycle.

The response should be checked at regular intervals.

5.5 Relative Density

The relative density or buoyancy of the gas or vapour with respect to air is a very important consideration. This determines its propensity to rise or fall when released into the atmosphere.

Gases or vapours with a buoyancy less than air will tend to rise from the source of release.

Conversely, gases or vapours heavier than air will tend to fall and accumulate in concentrations for long periods of time.

This is a particular problem in pits, trenches, machine rooms, etc. Normal air movements in and around such gas concentrations will have the inevitable effect of producing zones of of highly toxic mixtures.

This knowledge of the characteristics of the gas assists when positioning the gas sensor.

The behaviour of the gas accumulation will also be affected by the velocity and location of the gas release and by ambient air movement caused by ventilation systems or draughts.

Pockets of gas can be trapped in trenches or ceiling cavities, all of which adds to the unpredictability of critical gas concentrations.

5.9 Sensitivity

Electrochemical cells for toxic gases can be affected by other interfering gases which may displace the subject gas being monitored. Steam laden atmospheres and condensation can also reduce the sensitivity.

5.10 Flammable

Be aware that some toxic gases are also ‘flammable’ at high percentage concentrations.

5.11 Biased Sensors

Some gas sensors must be continuously powered to maintain the calibration.

If the gas head is removed from any supply voltage for greater than 10 minutes, itcould take 24–48 hours to restore its calibration.


6.1 0.4...2V Output Signal

A low impedance two-wire voltage output signal requiring a separate power supply to the sensor. This can be derived from a Trip Amplifier or Programmable Sensor Controller, when one of those is used as the monitoring instrument.

This connection configuration works well up to about 10 metresdistance between the sensor and the monitoring equipment.

Both the signal and the power supply to the sensor are being carried in the common 0V conductor so at some point – influenced by the length of the cable and the resistance of the cable cores – the current flowing in the 0V conductor will impose an unacceptable voltage error onto the signal.

This effect can be reduced on long distance connections by increasing the size of the cable cores, or even better, running a separate 0V conductor to power the sensor enabling operating distances up to 1000m.

The gas sensing module will gradually change its responsecharacteristics, by a small amount, during normal use. The output signal is standardised so the module can be quicklychanged when necessary.

The gas sensing module may be re-calibrated when required, using a Trolex TX6520 Gas Test Kit equipped with both Air and Test Gas canisters.

8.1 Prepare to Calibrate

• The sensor should be powered for a minimum of 30 minutes prior to commencing calibration.

• Connect the application tube of the gas test kit to the inlet aperture of the gas sensing module.

8.2 Calibrate Zero

• Apply purge air, at a flow rate of 0.3...1.0 l/min.

• Allow reading to stabilise.

• If necessary, adjust Offset potentiometer until display reads 0.00.

• Remove purge air.

8.3 Calibrate Span

• Apply calibration gas, minimum of 25% of full scale.

• Allow reading to stabilise.

• Adjust Span potentiometer until display reads the same value asthe calibration gas being used.

• Remove span gas.

TEST GAS

It is good safety practice to carry out regular preventative maintenance toconfirm correct operation.

9.1 Output Signal

• Check the response of the sensor at pre-determined intervals by injecting a test gas using a Trolex TX6520.32 Gas Test Kit.

Compare the value of the display with the value marked on thetest gas canister.

• Insert an approved test meter into the signal line and compare the value of the display with the measured value.

• Change the gas sensing module if necessary.

• Recalibrate.

9.2 Annual Safety Check

The main transmitter itself will not normally require maintenance or calibration but it is advisable to return it to the Trolex Product Support Department for an annual safety check.

9.3 Damaged Sensors

A Sensor that has been dropped or damaged in any way should be taken out of service immediately for inspection repair and re-calibration.

9.4 Record Keeping

Institute a regular calibration and maintenance procedure and keep a record.

Incorrect use of the Sensor or inadequate maintenance may not necessarily be self evident in the Sensor and consequently it must be regularly checked and maintained.
