Pressure transmitter for the metering of differential pressure

7 causes wherefore also you should buy differential pressure sensing elements by Senti-Solutions.com:

1. Individual measurement ranges in approval to your demands
2. You receive a calibrating certificate to any bought differential pressure sensor on request; entirely gratis!
3. No Asia importation, our differential pressure transmitter are assembled here in Germany!
4. Save yourself storehouse expenses by including larger product bands with less pressure transmitters. How this goes? Further read!
5. Switch-selectable approved measurement ranges, i.e. You buy 1 differential pressure transmitter for 3 different measurement ranges (at rival products you must acquire 3 parts for)
6. Switch-selectable output signals, i.e. You acquire 1 differential pressure sensor and can fix the output signal at the pressure transducer, (at rival products you must acquire a pressure sensor for every output signal)
7. You have read entirely right! To achieve the performance range of one of our differential pressure transducers, you should acquire at least 9 rival goods! Save yourself the cash!

How do our differential pressure sensing element function? Study this in our summarization!

The differential pressure in non-aggressive gasses and atmospheres can be grasp with the pressure sensor for the metering of differential pressure. The used metering item is a pressure detector produced into Si technology. The pressure sensor use a wheatstone resistance bridge for the capturing of the pressure alteration which was diffused into the silicon crystal. The measurement signal gets temperature and pressure compensated by means of IC. Each pressure transducer will be calibrated during the assembling method. Through this a high reliability and correctness of the pressure sensor is guaranteed.

Dissimilar signals are ready for use as an output signal depending on application example. Besides the norm signals of 0 …. 10 V or 4 …. 20 mA the pressure transducers for differential pressure can also be delivered with a gSPI interface. It is also possible to deliver the differential pressure pressure sensors with mixed output signals so that the output signal can be chosen at the location of use by means of jumper.

The gSPI interface is a bus system. Up to 120 pressure transmitters can be achieved at this. The coupling of pressure detectors for differential pressure without gSPI interface is carried out by bus connection modules to the gSPI bus.

The pressure-metering transmitters are obstructed in a synthetic housing in IP65. The pressure-gauging sensor can alternatively be assembled with a 4-digit LCD for the indication of the measurement. The unity is also shown on the display as well as the measurement.

The pressure-metering transmitter can instead be distributed for differential pressure also in a extreme-grade steel execution. The differential pressure can be measured in liquids and aggressive conditions with that. At this version the gauging item consists of a pressure sensor established in thin film technology on a extreme-grade steel membrane. It is therefore guaranteed that all medium touching parts consist of exorbitant-grade steel completely. A wheatstone resistance bridge circuit is used for the detection also at this pressure sensor. By use of a semiconductor chip the measurement signal of the wheatstone bridge gets temperature and pressure compensated. Previous to delivery this pressure transducer is also calibrated to be able to attest a extreme precision and accuracy.

This pressure-measuring transducer can be delivered with the output signals 0 …. 10 V, 4 …. 20 mA or 0 …. 20 mA.

The use of these pressure sensors for differential pressure is carried out in the clean room, medication and filtering technique in ventilating systems and climate channels into paint spraying cabins or into canteen kitchens.

Each differential pressure pressure sensor can be distributed on call with a calibrating certificate also with DKD-calibrating testification.

Hints

You may link to this page!

The pressure transducer is maintenance-free.

This page was arranged with care. It, even so, was not possible to take into account all conceivable function circumstances. If you should miss notes for your particular formulation, use the contact form for your questions.

Indications for safety causes

Notice the corresponding national safety regulations (e.g. DIN VDE 0100 part 410) absolutely for assembly, putting into operation and operation of these pressure sensors.

Mistakes and changes in the sense of technical improvements reserved.
