Working Principle: The oil pressure sensor of automobile is an important device to detect the oil pressure of automobile engine, and the measured data can help control the normal operation of the engine.

The oil pressure sensor is installed on the main oil channel of the engine. When the engine is running, the pressure measuring device detects the oil pressure, transforms the pressure signal into electrical signal and sends it to the signal processing circuit. After voltage amplification and current amplification, the amplified pressure signal is connected to the oil pressure indicator through the signal line.
