Differential 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. In the trap system of the vehicle exhaust part, the exhaust gas pressure difference of the front and rear channels of the trap is measured, and the ECU selects a reasonable trap 'regeneration' trigger timing, and additional fuel injection amount for the EGR and air filter. System measurement differential pressure.
