Product Details

Stainless steel piezoresistive pressure sensor chips

Description of pressure sensor chips :
YPS-19 is 316L SS Piezoresistive Silicon Pressure Sensor , 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 pressure sensor chips :

♦ Measurement range: 0~10KPa~100Mpa ♦ O-ring mount

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

Application of pressure sensor chips :

♦ Measurement pressure of gas and liquid                      ♦ Petroleum exploitation
♦ Water supply,warm supply of town                            ♦ Process control system
♦ Aviation and navigation inspection                              ♦ Hydraulic pressure

Electrical Data of pressure sensor chips :
