SIEMENS SITRANS P Compact
The SITRANS P Compact is an analog transmitter for measuring absolute and relative pressure which has been
developed specially for the requirements of the food/pharmaceutical and biotechnology industries.
Overview
The SITRANS P Compact pressure transmitter is designed for the specific requirements of the food, pharmaceuticals and biotechnology industries.
The use of high-quality materials guarantees adherence to hygiene provisions.
Particular importance was placed on high surface quality. In addition, the system can be electropolished.
A further important feature is the hygienic design of the process connection with different aseptic connections.
The fully welded stainless steel housing can be designed with degree of protection up to IP67.
By means of corresponding temperature decouplers, the SITRANS P Compact transmitter can be used for temperatures up to 200 °C (392 °F).

Function
Process pressure acts on a piezo-resistive semi-conductor measuring bridge via a remote seal diaphragm by means of a transfer fluid.
The pressure transmitter converts the measured pressure values into a load-independent current signal.
A compensation network achieves a large degree of independence of the output signal from the ambient temperature.
With a specially adapted remote seal connection with minimized system volume, the influence of the process temperature
on the output signal is reduced significantly as compared to a conventional screw connection.
The pressure transmitters can be supplied with an unregulated DC voltage of 10 to 30 V.
The output signals common in measuring technology are available.
