It has the advantages of no mechanical moving parts (i.e. no contact points), high accuracy, high reliability, long service life, and meets the requirements of the development of automotive electronics.
The oil pressure sensor is mainly used to measure the oil pressure of engine lubricating oil and provide a signal to the ECU. The ECU controls the status of the variable oil pump through the signal or displays the oil pressure through the oil pressure gauge;
The pressure acts on the ceramic substrate of the charged bridge, causing the deformation of the ceramic membrane and resulting in a change in the opposite side resistance, forming a weak potential difference; The signal conditioning circuit amplifies and adjusts the voltage to output a standard pressure voltage corresponding output curve.
