The engine oil pressure alarm sensor is an important device for monitoring the engine oil pressure. Here is its relevant introduction:
Structure and Principle
The electronic engine oil pressure alarm sensor consists of a thick-film pressure sensor chip, a signal processing circuit, a housing, a fixed circuit board device, and two leads (a signal line and an alarm line). The signal processing circuit includes a power supply circuit, a sensor compensation circuit, a zero adjustment circuit, a voltage amplifier circuit, a current amplifier circuit, a filter circuit, and an alarm circuit. When the engine is running, the sensor installed on the engine's main oil gallery has a pressure measurement device that detects the oil pressure. It converts the pressure signal into an electrical signal and sends it to the signal processing circuit. After amplification, it is connected to the oil pressure indicator via the signal line. At the same time, it is ......
