Abstract
A filling level sensor in a fuel tank of a motor vehicle includes a substrate having a resistance network arranged thereon, one or more electrical contacts, which are in contact with the resistance network in order to produce an electrical signal depending on the pivoting of a lever arm, and a float, which is fastened to the lever arm in such a way that the lever arm can be moved by the float in accordance with the filling level. The filling level sensor is connected to electronics, and the electronics are designed in such a way that the electronics provide a respective corresponding electrical target signal for each of the electrical signals generated by the filling level sensor.

31. A method for operating a filling level sensor, comprising:
-
placing electrical contacts in contact with a resistance network as a function of pivoting of a lever arm, such that an electrical signal which corresponds to the filling level is produced in the resistance network; feeding the produced electrical signal to electronics; and generating in the electronics an electrical setpoint signal corresponding to the produced electrical signal.
