Abstract

There is provided a fuel level sensing device for a fuel tank for sensing a remaining fuel level of a fuel tank by a change in a measured resistance value depending on a position of a slider in contact with a resistance substrate, wherein the resistance The substrate includes: a first segment part and a second segment part arranged to be spaced apart from each other, the resistance setting part of the second segment part is connected to the positive electrode terminal, and the connection part of the first segment part passes through the negative electrode A lead wire is connected to the negative electrode terminal, and a connection point of the negative electrode lead wire connected to the connection member is formed between both ends of the connection member in the length direction. Therefore, the resistance deviation of the measured resistance value depending on the variation of the slider position can be reduced.

Description

technical field [0001] The following disclosure relates to a fuel level sensing device for a fuel tank for sensing a fuel level of remaining fuel in a fuel tank provided in a vehicle. Background technique [0002] Generally, a vehicle is provided with fuel tanks that can accommodate various fuels required to drive an engine, and a fuel level sensing device is provided in a fuel tank that accommodates liquid-phase fuel among these fuel tanks to allow the driver to recognize The remaining level of fuel. [0003] Fuel level sensing devices for fuel tanks are mainly classified into mechanical fuel level sensing devices and electronic fuel level sensing devices. In mechanical fuel level sensing devices, a float floats on liquid-phase fuel, To allow the resistance value to change according to the height of the float, the electronic fuel level sensing device does not use a separate float but directly senses the height of the liquid-phase fuel, and the mechanical fuel level sensing...
