Pressure Sensor WPAH02

  • WPAH02.png


WPAH02 ceramic pressure sensor is a ceramic piezoresistive pressure sensor refined by thick film process using imported refined ceramic base. Dimensions Φ 18mm*6.35mm. Ceramic is recognized as a highly elastic, corrosion-resistant, wear-resistant, shock- and vibration-resistant material. The good thermal stability of ceramics and the high-temperature sintering process of thick film make the working temperature range of the ceramic pressure sensor as high as -40~125℃. The high elasticity and creep resistance of ceramics make the ceramic pressure sensor have good long-term stability. In addition, the corrosion resistance of ceramics makes it unique in the fields of refrigeration, chemical industry and environmental protection.


* Ceramic sensitive diaphragm with high overload capacity
* Zero and full scale laser calibration
* Excellent anti-corrosion and anti-wear properties
* Anti-shock, anti-vibration
* High precision and high stability
* Wide operating temperature range
* Small size, easy to package
* Environmental protection
