Introduction To The Principle And Characteristics Of Automobile Oil Level Sensor

The automobile oil level sensor can float on the surface of the oil layer. Using the principle of leverage, the other end of the float is a potentiometer. The amount of oil determines the level of the float. The other end of the potentiometer will reach a different potential with the oil level, which is displayed on the dashboard. Is displayed on the.

The principle of the automobile oil level sensor is wire wound resistance, the resistivity is determined by the resistance wire material, and the resistance value is determined by the number of turns of the material resistivity coil. Therefore, the stable performance of wire-wound resistors is the preferred factor for long-term use of automotive fuel sensor. The oil volume sensor adopts small wire diameter, high resistance value, closely arranged wire wound resistors, which have the characteristics of stable performance, reliable structure and high resolution.

The sensing part of the oil level transmitter (sensor) is a coaxial container. When the oil enters the container, it causes a change in the capacitance between the sensor housing and the sensing electrode. This change is converted by the circuit and performed accurately. Linearity and temperature compensation, output analog signal or data communication for display instrument or other equipment.

Capacitive oil level sensor features:

1. Independence: The fuel consumption value is obtained directly by measuring the fuel volume of the fuel tank, without any effect or influence on the oil system/pipeline.

2. Uniqueness: It has the function of auto-cutting the range, the user can recalibrate by pressing the button, and the digital output can also be equipped with debugging software.

3. Stability: Without any mechanical moving parts, mature and stable circuit structure and high-quality components will enable the sensor to be used continuously for several years without replacement.

4. Safety: Directly replace the original car's fuel gauge, no need to drill holes in the fuel tank to install capacitive sensors, the electronic cabin adopts explosion-proof design and has passed explosion-proof certification.
