cummins qsl9 oil pressure sensor location
The oil sensor of Cummins qsl9 engine is installed at the lower rear of the left side of the engine body. The automobile oil pressure sensor is an important device to detect the oil pressure of the vehicle engine, and the detected 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, 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.Change the ratio of the current passed by the 2 coils inside the oil pressure indicator to indicate the engine oil pressure. The pressure signal amplified by voltage and current is also compared with the alarm voltage set in the alarm circuit. When it is lower than the alarm voltage, the alarm circuit will output an alarm signal and light up the alarm lamp through the alarm line.
Reliability of oil pressure sensor:
The process of oil pressure detection needs to be carried out during the engine operation. The working conditions and temperature change obviously. At the same time, the road conditions will also affect the detection during the vehicle driving. The engine bears huge heat load, impact, vibration, etc., so the working condition of the sensor is also negatively affected by the harsh environment such as high temperature, humidity, impact, vibration, corrosion, oil pollution, etc.Therefore, reliability is the first consideration of product design, and reliability design and product reliability analysis run through the entire development process. When meeting the reliability, the most important thing is the selection and combination of product components. The space left by the engine for the sensor is already very limited, so the sensor should use chip mounted components as far as possible.
