FILL LEVEL SENSOR, MEASURING METHOD FOR DETERMINING A CONTACT PRESSURE OF A CONTACT AGAINST A CONTACT PATH OF A POTENTIOMETER AND DEVICE FOR CARRYING OUT THE MEASURING METHOD

摘要

A fill level sensor (1) for a fuel tank comprising a bracket (4) that can be pivoted over a support (5) has an opening (9) inside said support (5). A measuring tip (13) can be guided through the opening (9) against a part connected to contacts (10) of a potentiometer (7), and a lift-off force of the contacts (10) can be determined. The measurement of the lift-off force ensues with a low level of friction and close to the contacts (10).
