Pressure Sensors PC50
Product overview
PC50 Piezoresistive Silicon 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.
PC50 sensor packages piezoresistive silicon sensitive 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 sensitive 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.
PC50 sensor adopts O-ring for pressure sealing, easy to install. Our company can also undertake the special customization according to the requirements of the customers, for example, all-welded structure, wide temperature compensation, highly reliable, anti-strong shock and anti-vibration pressure sensors, especially for supporting the national defense weaponry.
