Product presentation

The differential pressure sensor, used in automobile engines, Real-time monitors the pressure difference between the front and rear exhaust particle channels. Integrated with the electronic control unit (ECU), it optimizes control strategies to reduce harmful emissions and comply with emission standards. This product uses the advanced MEMS technology, based on a MEMS pressure sensor chip with piezoresistive effect and a ASIC chip high performance signal conditioning. It offers high precision, fast response, increased reliability and remarkable stability, while being economical.
