HT20 is piezoresistive silicon differential 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. It has high stability, good reliability ,high static pressure. It is widely used in field which measure differential pressure.

Features
Wide measurement range: 0~20KPa~2Mpa
Full 316L.S.S
316L stainless steel diaphragm
High static pressure
High accuracy and stability

 
Application
Measurement pressure of gas and liquid
