Absolute pressure sensor WPAH31

ceramicpiezoresistiveDC

Description The WPAH31 is a high-performance ceramic piezoresistive pressure sensor constructed from a premium ceramic base using thick-film technology, integrated with temperature compensation. Measuring Φ18mm×6.35mm, its ceramic structure offers inherent advantages: high elasticity, corrosion resistance, wear resistance, and immunity to impact/vibration. The ceramic’s thermal stability and high-temperature sintering process enable operation across -40～125℃, while its creep resistance ensures long-term stability. This makes it ideal for refrigeration, chemical, and environmental applications where corrosion resistance is critical.
