PC10 Piezoresistive Silicon Pressure Sensor
Features
Applications
Product overview
PC10 piezoresistive silicon pressure sensor is the core component for the manufacture of pressure sensors and pressure transmitters. As high-performance pressure sensitive component, PC10 can be easily amplified and assembled into the pressure transmitters with standard signal output.
PC10 packages diffused silicon pressure sensitive die to 316L stainless steel housing. External pressure is transmitted to pressure sensitive die through stainless steel diaphragm and internally sealed silicon oil. Pressure sensitive die does not directly contact with measured medium, forming all solid structure of pressure measurement. So the product can be applied to a variety of occasions, including harsh corrosive medium environment.
PC10 uses O-ring for pressure seal, which is easy to install.
The company can also undertake special customization based on the needs of users, such as pressure sensors of all welded structure, wide temperature compensation, high reliability, anti-shock and anti-vibration sensors, especially for national defense weapons and equipment.

(1) Calculate according to BFSL least square method.
(2) In the compensation temperature range, refer to 30 ºC for 0 ºC ~ 60 and -10 ºC ~ 70 ºC, and refer to 32.5 ºC for -20 ºC ~ 85 ºC.
(3) After passing high and low temperature, return to the reference temperature.
