SENSOR FOR DETECTION OF THE FILLING LEVEL OF A LIQUID IN A CONTAINER, AND FUEL CELL SYSTEM HAVING A SENSOR SUCH AS THIS

摘要

The invention relates to a sensor for detection of the filling level of a liquid in a container, having a metallic housing (2) with an opening (3) from which an element (5) in the form of a rod extends, which is formed from a dielectric material (6) in which a detector element (7) is embedded, wherein an electrically insulating material (12, 15, 16) is formed at least in places on the outside (11) of the element (5) in the form of a rod and is formed at least in places on the front rim (4) of the housing (2) adjacent to the opening (3) in the housing (2). The invention also relates to a fuel cell system having a sensor such as this.
