Product Description
The differential pressure sensor measures the exhaust pressure difference between the front and rear channels of the exhaust particle
catcher in the automotive engine for real-time monitoring by the ECU, optimizing control strategies, reducing harmful gas emissions and complying with emission standards.
This product adopts advanced MEMS principle, the core technology is based on piezoresistive effect MEMS pressure sensor chip and high-performance signal conditioning chip ASIC chip.
It is a cost-effective sensor product with high precision, fast response speed, high reliability and good stability.
