High Stability Piezoresistive Silicon Pressure Sensor   

 

Description of High Stability Piezoresistive Silicon Pressure Sensor

High Stability Piezoresistive Silicon Pressure Sensor chip, the main element is a diffused silicon with high stability. It utilizes silicon oil to transfer pressure from 316L stainless steel diaphragm to sensing element. The sensing element uses 316L stainless steel to packing and thick film circuit to do temperature compensation and zero correction. It has high reliability and stability.

 

Features of Piezoresistive Silicon pressure sensor Wide pressure range ♦ Measurement range: 0~10KPa~100Mpa                      ♦ O-ring mount

♦ High Accuracy and stability                                       ♦ Piezoresistive silicon sensing element
♦ Full 316L Stainless steel
