where is the oil fuel level sensor of the car located
In general, the oil fuel level sensor of the car is located inside the fuel tank and together with the oil pump. The function of the car's oil level sensor is to detect the amount of oil. This sensor is a component that detects the position (height) of oil inside the container by utilizing the change in capacitance between the sensor housing and the sensing electrode caused by oil entering the container, and converting this change into a change in current . The electronic oil pressure sensor consists of a thick film pressure sensor chip, signal processing circuit , housing , fixed circuit board device , and 2 leads . The signal processing circuit consists of a power supply circuit , a sensor compensation circuit , a zero adjustment circuit , a voltage amplification circuit , a current amplification circuit , a filtering circuit , and an alarm circuit.
Thick film pressure sensor is a new type of strain gauge pressure sensor that emerged in the 1980s, developed using the piezoresistive effect of thick film resistors printed and sintered on ceramic elastomers. Directly print and sinter four thick film resistors on a ceramic elastic membrane, and connect them through conduction bands to form a Wheatstone bridge.When the measured liquid level pressure acts on the ceramic elastomer , the elastic membrane undergoes bending deformation. At the same time, the thick film resistor printed on the elastic membrane also undergoes the same amount of strain . Two of the thick film resistors undergo compression strain, resulting in a decrease in resistance value . The other two are subjected to tensile strain, and the resistance value increases. In this way, the measured pressure value is converted into a bridge output signal, and the signal size is proportional to the pressure.
If the car shows a malfunction in the oil level sensor, it may be due to the oil pressure or fluid in your car itself, which is insufficient fuel. What would be the best time for you to drive to this gas station and fill it up? Because there is an oil pump, if. In case of oil shortage. It will cause the oil pump to remain idle for a long time, which has a significant impact on the oil pump. So I suggest that you carry out maintenance in a timely manner.
