Pressure switch for the metering of pressure

7 causes wherefore also you should buy a pressure switch by Senti-Solutions.com:

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

How do our pressure switch function? Study this in our summarization!

The pressure in non-aggressive gasses and atmospheres can be grasp with the pressure switch for the metering of 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 switch 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 switch can also be delivered with a gSPI interface. It is also possible to deliver the pressure switch 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 and pressure switches can be achieved at this. The coupling of pressure switches without gSPI interface is carried out by bus connection modules to the gSPI bus.

The pressure-metering switch are obstructed in a synthetic housing in IP65. The pressure-gauging switch 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 pressure also in a extreme-grade steel execution. The 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 switch is also calibrated to be able to attest a extreme precision and accuracy.

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

The use of these pressure switches 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 pressure switch can be distributed on call with a calibrating certificate also with DKD-calibrating testification.

Hints

You may link to this page!

The pressure switch 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 switches.

Mistakes and changes in the sense of technical improvements reserved.
