WTsensor / High Performance Pressure Sensor P19


P19 High Performance Pressure Sensor is the core component for producing pressure sensors and pressure transmitters; as a kind of pressure sensitive elements with high performance, it can be conveniently processed through amplifying, and assembled into the transmitter with the standard signal output.

P19 High Performance Pressure Sensor packages highly reliable pressure die into 316L stainless steel housing; the external pressure is transmitted to the sensitive die through the stainless steel diaphragm and internally sealed silicon oil; the pressure die does not directly contact with the measured medium, so as to form all solid structure of pressure measurement, so this product can be applied to a variety of occasions, including harsh corrosive medium environment.

P19 pressure sensor adopts O-ring for pressure sealing, easy to install.

The company can also undertake special customization according to user needs, such as pressure sensors with fully welded structure, wide temperature compensation, high reliability, strong impact resistance, and vibration resistance, which are more suitable for replacing imported products.
