Abstract
A fill level sensor for a fuel tank of a motor vehicle includes electrical structures that consist of different materials. Sliding contact track structures exposed to the fuel consist of a gold-containing paste. Conductor structures are protected by a cover from contact with the fuel and consist of an especially inexpensive material. The fill level sensor therefore is highly resistant to corrosive fuels and can be produced at low cost.
