      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
