Original Fuel Level Sensors D2330-41801 and D2330-88000 (Best Quality)

A fuel level sensor is a device that monitors the fuel level in the tank. It converts changes in liquid level into an electrical signal using physical or electronic principles. They are mainly divided into mechanical (e.g., float type) and electronic (e.g., capacitive, ultrasonic type). Their core function is to transmit fuel level data to the instrument panel in real time, ensuring the safe operation of the fuel system.

Main Types and Principles

Float Type: A float moves with the fuel level, driving a potentiometer to change the resistance value and output a signal. Simple in structure but easily affected by oil residue.

Capacitive Type: Utilizes the difference in dielectric constant between fuel and air to detect changes in capacitance between electrodes. High accuracy and no mechanical wear.

Ultrasonic Type: Measures distance through the time difference of sound wave reflection. Suitable for high-temperature or corrosive fuels.
