Pressure sensitive element

AAbbssoolluuttee pprreessssuurree ((PPabs))

The pressure which applies to thevacuum in the universe (zero pressure)is known as absolute pressure.Absolute pressure has “abs” as itsindex.

MMeeaassuurriinngg pprriinncciippllee

When designing pressure meters, the principle of the effect of pressure on a defined area is almost always used. This is thenretraced to a measurement of force.

The following formula applies:

DDiiffffeerreennttiiaall pprreessssuurree,, pprreessssuurreeddiiffffeerreennccee ((Δpp))

The difference between two pressuresp1 and p2 is known as pressuredifference (Δp= p1-p2). If the differencebetween two pressures is a variable,this is referred to as differential pressure(p1,2).

AAttmmoosspphheerriicc pprreessssuurree ddiiffffeerreennccee,,ppoossiittiivvee pprreessssuurree

Atmospheric pressure difference (pe) isthe difference between an absolutepressure (pabs) and the respectiveatmospheric pressure (pe = pabs - pamb).This is generally referred to as positivepressure.

AAttmmoosspphheerriicc aaiirr pprreessssuurree ((PPamb))

This is the most important pressure for life on earth. Atmospheric pressure iscreated by the weight of the atmosphere surrounding the earth. The atmospherereaches a height of up to approx. 500 km. Pressure decreases constantly up to thisheight (absolute pressure Pabs = zero). Atmospheric air pressure is also influencedby fluctuations in the weather. The average Pamb at sea level is 1013.25Hectopascal (hPa) or millibar (mbar/ normal pressure in accordance with DIN 1343).Typically this value can fluctuate by ±5 % if there are low or high pressure weatherareas.

There is a displacement of 1-3 mm inelastic pressure meters. The deformation in electrical pressuresensors is only a few µm. Due to thisvery low mechanical deformation,electrical pressure meters / sensorshave an excellent dynamic performanceand low material stress resulting in highendurance levels and long-term stability.Electrical pressure meters can also bemanufactured in very small sizes.

An additional advantage is the easy-to-read display. Considering today’stechnology standards, accuratepressure measurement is becomingmore and more important. Precision

measuring meters have an accuracy of±0.05 % of the full-scale value. In thecase of mechanical manometers, suchaccuracies cannot be read on accountof the parallax error and mechanicalperformance of the springs. Electricalprecision meters with LCD display oftenhave a resolution in the thousandthrange of 0.001.

• Absolute pressure probes to 2000hPa

• Relative pressure probes to 400 bar• Temperature probes from -200 to

+1250 °C • Probes for measuring

current/voltage

Wide selection of probes

• Measurement protocols can beprinted on site. No awkward cablesrequired on account of the infraredinterface.

• Long-term legible thermal paperensures that measurement datadocumentation can be stored for upto 10 years.

Documentation on site

• The saved measurement data can beeasily analysed and processed usingthe software available.

• Readings are taken by the instrumentand can be depicted online by thesoftware.

• Pressure drops can be protocolledonline in cycles of 0.05 seconds in the

Fast Measurement menu. Since, inmost cases, pressure drops cannotbe predicted, a rule can be definedvia the trigger function; the pressuredrops are then filtered out and storedseparately for the user in indexedpages.

Easy data management via PC

All transmitters or non-Testo probes (in 2or 4 wire systems, 18 V) can beconnected to the 4 to 20 mA interface.Scaling is carried out on the hand-heldmeasuring instrument.

Major benefit: The transmitter connecteddoes not need its own power; it issupplied by the testo 521 or testo 526pressure meter.

Inspection of transmitters with 4 to 20 mA interface

• Measurement data can be savedseparately or as a measurementseries. The measurement rate (0.04seconds, 1 second to 24 hours) andthe number of values to be saved arefreely selectable. The maximummemory size is 25,000 readings.

• The readings are saved underseparate names for the sites (max. 99sites) - with retracing guarantee.

• Online measurement for largequantities of data can be activated viaPC.

When leaks are detected, thedisplay changes from green tored. An audible signal additionallyinforms of leakages detected.Using the earplug, the testo 316can also be used in loudsurroundings. The maximumindicator function showsmaximum leakages and sofacilitates the identification ofleakage locations.

If maintenance is due in a refrigerationunit or the unit indicates "error", theservice technician must first procure anoverview of the system history (workcarried out in the past, exchanged parts,previous errors etc.) This is done bystudying system files or by contactingthe service technician who carried outmaintenance work on the unit before.These jobs are time-consuming andthere is also the risk of the refrigerationchain being interrupted for a longerperiod of time. testo 556 has an externalmemory chip on which system historycan be documented. Fast information onall relevant system parameters isguaranteed thus helping to reducesearching and downtimes.

MMeemmoorryy cchhiippThe memory chip consists of a “readonly” section (values can only be writtenon chip using PC and software) as wellas a section which is “readable” and“writeable” by the instrument.

RReeaadd oonnllyy mmeemmoorryy sseeccttiioonnSystem data is copied onto this sectionof the memory by a PC before thesystem is initialised (e.g. system planner,manufacturer, refrigerants filled,refrigerant quantities, operating pressureetc.) This part of the memory can beread by the installer but cannot bemodified or deleted. Once programmedthe memory chip is attached as asystem component together with therating plate.

IInnssttaallllaattiioonn aanndd hhaannddlliinngg mmaaddee eeaassyyMemory software is activatedautomatically in the memory chip once

testo 556 is initialised. When working ona system, the data from the lastmaintenance is first read out. Thisprovides a fast overview and helps toassess the current system status. Onceservice has been carried out or the errorhas been eliminated, current data issimply transmitted to the memory chip.In this way, the memory chip receivesthe complete system history.
