How Motorcycle Fuel Level Sensor PCB Works ?

Motorcycle Fuel Level Sensor PCBs operate by using a float mechanism that moves up and down with the fuel level in the tank. This movement is translated into an electrical signal via a variable resistor (potentiometer) integrated into the PCB. As the float rises or falls, the resistance changes, which is then converted into a voltage signal. This signal is sent to the motorcycle's dashboard or digital display, where it is interpreted and displayed as the current fuel level. The process can be broken down into the following steps:

● Float Movement: The float inside the fuel tank moves with the changing fuel level.

● Resistance Change: The movement of the float alters the resistance in the potentiometer on the PCB.

● Signal Conversion: The change in resistance is converted into a voltage signal proportional to the fuel level.

● Signal Transmission: The voltage signal is transmitted to the motorcycle's dashboard or digital display.

● Display Interpretation: The display interprets the signal and shows the current fuel level to the rider.
