Product overview:
PC13 piezoresistive silicon pressure sensor is the core component for the manufacture of pressure sensors and pressure transmitters.
As high-performance pressure sensitive component,PC13 can be easily amplified and assembled into the pressure transmitters with
standard signal output.
PC13 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.
