fuel gauge level sensor
Fuel gauge level sensor is a part that changes the capacitance between the sensor shell and the sensing electrode after the oil enters the container, and converts this change into a current change to detect the position (height) of the oil in the container. The sensing part of the automobile oil level sensor is a coaxial container. When the oil enters the container, the capacitance between the sensor shell and the sensing electrode changes
Through circuit conversion, accurate linearity and temperature compensation are carried out, 4-20mA standard is output, and the signal source will be displayed on the instrument
With the help of the capacitance formed between the dry probe and the container, the oil level sensor changes linearly with the fuel level, and converts the change of fuel level into linear transmission
It can directly display the fuel level height or send it directly to the remote monitoring system through wireless transmission. The same sensor can change the measuring medium or change the installation environment at any time. It can automatically adapt and accurately measure without new calibration, and is not affected by the change of dielectric constant and temperature.
Working principle of automobile oil level sensor:
1. Generally speaking, it is a sliding rheostat, and the resistance value is controlled by a floating. With the increase of oil quantity, the resistance value will also change;
2. When the load voltage is fixed, the output current will change. The current value is reflected on the vehicle instrument and converted into gasoline according to a certain proportion;
3. Generally, due to the irregularity of the oil tank, the resistance of the rheostat changes irregularly.
