PC13 Piezoresistive Silicon Pressure Sensor
Product overview
The PC13 piezoresistive silicon pressure sensor is the core component for manufacturing pressure sensors and pressure transmitters. As a high-performance pressure sensitive component, PC13 can easily amplify signals and be assembled into pressure transmitters with standard signal output.
PC13 packages diffused silicon pressure sensitive die to a 316L stainless steel housing. The external pressure is transmitted to the sensitive die through the stainless steel diaphragm and the internally sealed silicon oil. The pressure sensitive die does not directly cntact the measured medium, forming an all-solid structure of pressure measurement. This allows the product to be applied to a variety of occasions, including harsh corrosive medium environments.
PC13 uses the O-ring for pressure sealing, making installation easy.
Our company can undertake special customization based on users’ needs, such as pressure sensors with wide temperature compensation, high reliability, shock resistance, and vibration resistance.
