Description

The CRA-P-331 is a differential pressure transmitter for industrial applications and is based on a piezoresistive stainless steel sensor, which can be pressurized on both sides with fluids or gases compatible with SST 1.4404 (316L) and 1.4435 (316L).

The compact design allows an integration of the CRA-P-331 in machines and applications with limited space. The CRA-P-331 calculates the difference between the pressure on the positive and the negative side and converts it into a proportional electrical signal.
