Product Description
WA18 Diffused Silicon Oilless Pressure Sensor      

WA18 series is MEMS technology based piezoresistive silicon sensor. It uses ceramic housing without isolation diaphram and silicon oil. WA18 is different with tranditonal diffused silicon diaphram-free sensors: pressure media touches directly with the back of pressure chip (the side without circuit), ensuring durability and long-term stability of the sensor. It is a kind of low cost and high performance OEM pressure measuring sensor designed for clear and non-corrosive gas and liquid.
Every sensor was strictly temperature compensated for both zero and span before shipment to ensure measurement accuracy in complex environment.
