Pressure Transmitter with Diaphragm Seal Type P1237

Pressure Transmitter with Diaphragm Seal Type P1237

The wide application field of pressure transducers is guaranteed by the high accuracy and the rugged design.

The stainless steel membrane is completely vacuumsealed, extremely burst resistant and applicable for all standard media for hydraulics, pneumatics, environmental engineering, process technology, semiconductor technology and automotive engineering. Thus, the use for standard applications of mobile hydraulics and other application areas is covered.

Due to the manufacturing process all pressure transducers are  individually pressure- and temperature tested.

The production occurs in accordance with the requirements of DIN EN ISO 9001:2008.

More info

The zero can be set easily with a magnet within ± 10 % of the nominal range.

To correct the zero point, hold a permanent magnet– a pin board magnet, for example – at the position marked on the pressure transmitter (i.e. a letter in a circle) for ½ to 2 ½ minutes after the power has been switched on. To correct the zero, atmospheric pressure is applied. Offsets for previously set values for initial and ultimate pressures will be corrected automatically by the device. A magnetic field applied outside of this set again.


Parameterization of measuring range (1:4), zoom, span and adjustment of characteristic diagram are possible with service tool or PC adapter and software. Programmable devices are only available with Electrical connection by Binder M12 (Binder series S763) or by cable.
The service tool or the PCF software are available accessory.


The sensors are free of maintenance.


We compiled this operating instruction carefully. Nevertheless, it was not possible to take all possibilities of application into account. If this data sheet should lack the solution of your special task, please don’t hesitate to contact us.


During installation, putting into service and operation of the pressure sensors, it is necessary to observe the relevant safety regulations that are in force in the country of the user (as for example, DIN VDE 0100). Errors excepted; subject to alterations in the sense of technical improvement.


Following ranges are availble from Tempress stock: 0-1/0-1,6/0-2,5/0-4/0-6/0-10/0-16/0-25/0-40/0-60/0-100/0-160 Bar.

The stock items are all with media contacted parts in stainless steel, G1/4B process connection and electrical connection MVS/Form A DIN EN 175301-803.

Diaphragm seal: please specify according to datasheets.

Pressure Transmitter with Diaphragm Seal Type P1237


The compensation and adjustment is carried out electronically. Thus the pressure transmitters have a very low total error and a very good long-term stability. The measuring cell is characterised by its high long-term resistance and long-term stability.
With the precision of modern electronics, the measured data can be captured accurately. Even the programming of the pressure transducers by the user can be realised on a service tool or PC programming kit. The graduation of the measuring range and the zero point can be set up through the digital interface. Furthermore sensor data can be read out from the device. By using permanent magnets the adjustment of the zero point can easily and securely be done at any time.
