Piezoresistive Silicon Pressure Sensor Φ10mm PC7
Product overview
PC7 silicon piezoresistive pressure sensor is a small diameter, high performance, high reliability, wide range pressure sensor. It uses imported pressure chips, optional constant current and constant pressure excitation and standard millivolt signal output.
PC7 packages diffused silicon pressure sensitive die in a φ10×8mm 316L stainless steel housing,which is led out by kovar pin. 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.
