engine oil pressure sensor
The function of the sensor is to monitor, and the oil pressure sensor is naturally used to detect the oil pressure. Once it detects insufficient oil pressure, it will alarm. But if the sensor fails, it won't affect your fueling, but it's also impossible to monitor the oil pressure. Once a problem occurs, it can also lead to engine failure, so be sure to know the oil pressure.
The role of the oil pressure sensor.The oil pressure sensor is used by you to detect the oil pressure. When the pressure is insufficient, it will alarm and the oil light on the instrument panel will light up. If there is no sensor, the engine will be irreversibly damaged when there is a problem such as lack of oil, so the oil pressure sensor plays a vital role.
The working principle of the pressure signal after voltage amplification and current amplification 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 light through the alarm line. There is a sliding resistor in the oil pressure sensor, which uses the oil pressure to push the potentiometer of the sliding resistor to move, change the current of the oil pressure gauge, and change the position of the pointer.
When the engine temperature is high, it is easy to produce sludge, so you need to pay attention to the maintenance of the engine and the selection of oil. It makes sense to choose a high-quality motor oil. Why high-quality motor oils, such as Shell, pay a lot of attention to the cleaning power of the product. It is because oil is related to engine lubrication, wear reduction, cooling and sealing. Poorly clean oil often cannot prevent the accumulation of carbon deposits. The accumulation of carbon deposits inside the engine will accelerate the wear of cylinder liners, pistons and piston rings. Serious damage to the engine,It is usually behind the engine, on the cylinder block, and next to the oil filter element base. There is a plug with one line on it, which is located on the front oil passage of the oil filter element. Thick film pressure sensor is a new strain type pressure sensor which appeared in the 1980s. It is developed by using the piezoresistive effect of thick film resistance printed and sintered on ceramic elastomer. Four thick film resistors are directly printed and sintered on the ceramic elastic diaphragm, and connected to form a Wheatstone bridge through a conducting belt.
