oil pressure sensor jeep grand cherokee
Where is oil pressure sensor of jeep grand cherokee:The car oil pressure sensor is close to the oil filter element and is an important device to detect the oil pressure of the car engine. The detected data helps control the normal operation of the engine. The oil pressure sensor is installed in the main oil passage of the engine.
When the engine is running, the pressure measuring device detects the pressure of the engine oil, converts the pressure signal into an 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, and the current ratio of the two coils in the oil pressure indicator changes to indicate the engine oil pressure.
The pressure signal amplified by the voltage and current is also compared with the alarm voltage set in the alarm circuit. When the voltage is lower than the alarm voltage, the alarm circuit outputs an alarm signal and lights the alarm lamp through the alarm line. The wiring method of the electronic oil pressure sensor is exactly the same as that of the traditional mechanical sensor. It can replace the mechanical pressure sensor and directly connect with the car oil pressure indicator and the low pressure warning light to indicate the oil pressure of the diesel car engine and provide a low pressure warning signal.
Compared with traditional piezoresistive oil pressure sensors, electronic automotive oil pressure sensors have the advantages of no mechanical moving parts (ie, no contact), high precision, high reliability, and long life, which meet the requirements of the development of automotive electronics. Due to the harsh working environment of automobiles, the requirements for sensors are very strict.
In the design of the electronic automobile oil force sensor, not only the pressure measuring device with high temperature resistance, corrosion resistance and high precision should be selected, but also the components with reliable performance and wide working temperature range should be selected, and anti-interference measures should be taken in the circuit. Improve sensor reliability.
