Pressure Sensor 9325000011,6284200061,4410430011,0034316406 for DAF

Basic principles of pressure sensors
The main working principle of pressure sensor includes piezoelectric effect, piezoresistive effect, strain effect and so on. Among them, piezoelectric sensors use the piezoelectric effect, that is, some materials will produce charges when subjected to external forces, by measuring these charges to sense pressure changes; Piezoresistive sensor makes use of piezoresistive effect, that is, the resistance value of the material will change when it is subjected to pressure, and senses the pressure by measuring the change of resistance value. The strain sensor uses the strain effect, that is, the material will deform when subjected to external force, and senses the pressure by measuring the deformation.
Types and classification of automotive pressure sensors
Automotive pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors according to different test pressure types. In addition, according to the different structure and principle, it can be divided into strain type, piezoresistive type, capacitance type, piezoelectric type and many other types. These different types of sensors have their own applications in automotive systems to jointly ensure the normal operation and driving safety of the car.
