Desorption pressure sensor

This product is made with advanced micro-electromechanical principle. The core technology is MEMS pressure sensor chip based on piezoresistive effect and high-performance signal conditioning AISC chip. It has excellent quality and precision package. It uses mature and reliable calibration, compensation 

and protection technology to respond. Fast, reliable, and stable, it is a cost-effective sensor product. The desorption pressure sensor can monitor the normal operation of the canister desorption system in real time, improve the desorption of the fuel vapor system, and reduce the emission standard.
