Low power consumption and high efficiency, resistant to high temperature and corrosion. High measurement accuracy
1. Applied to automotive exhaust emission systems, measuring the pressure of exhaust gases in the front and rear channels of some filters, and providing pressure signals to the ECU to select a reasonable trigger time for filter regeneration, as well as the amount of additional fuel injection and additional fuel injection;
2. Used for pressure difference measurement in automotive EGR and air filter systems.
Pressure conversion function: The pressure acts on the diaphragm of the charged bridge, causing deformation of the diaphragm to change the resistance on the opposite side, forming a weak potential difference signal conditioning circuit. By amplifying and adjusting the voltage, the output standard pressure sensor signal corresponds to the output curve;
