Working principle of fuel tank level sensor assembly 812W06125-0002:

Usually, it adopts the working principle of float type, capacitance type or resistance type. Taking the float type as an example, when the liquid level in the fuel tank changes, the float will float up and down, drive the potentiometer or other sensor elements through mechanical structures such as connecting rods, change its resistance value or capacitance value, and then change the output electrical signal to reflect the height of the liquid level; the capacitance type is based on the change of the fuel level in the fuel tank, which causes the dielectric constant of the medium between the capacitor plates to change, thereby causing the change of capacitance value to measure the liquid level; the resistance type uses the change of liquid level to change the length of the resistance wire in the sensor immersed in the fuel, thereby causing the resistance value to change to detect the liquid level.

Fuel tank level sensor assembly 812W06125-0002

Applicable models: Mainly applicable to Sinotruk HOWO T7H, Shandeka C7H, G7, C9H and other models.

Function: As a key component of the vehicle's fuel tank level monitoring system, this component can sense the height change of the fuel level in the tank in real time, and convert this physical quantity into an electrical signal, and then transmit it to the vehicle's dashboard or other control unit, so that the driver can intuitively understand the remaining fuel in the tank, so as to refuel in time. At the same time, it also provides important data support for the vehicle's fuel management system to ensure the normal operation of the vehicle.
