    摘要: A sensor element (30) measures a Hall voltage generated by a movable magnet (16). For this purpose, the sensor element (30) comprises a ceramic base element (40) which has connected therewith a detector element (46). The detector element (46) is protected with the aid of a cover element (42) against an aggressive environment produced by fuel or fuel vapors in a fuel tank (34) of a motor vehicle. The detector element (46) has connected therewith electric conductors (60) which are routed through the cover element (42) and/or the base element (40) for connecting the detector element (46) with a voltage source and/or an evaluation unit. The cover element (42) and possibly the base element (40) reliably encapsulate the detector element (46) against the aggressive environment such that by simple constructive measures the service life of the sensor element (30) is increased.

    摘要: A level transmitter for liquid containers, particularly fuel store tanks, comprising a housing in which a contactless sensor is arranged which is connected with an evaluating unit and operatively connected with a magnet that moves relative to the sensor when a float arranged at a first end of a lever moves so that the change of the magnetic field acting upon the sensor is transformed into an electric signal so that an output signal corresponding to the level of the liquid in the container is obtainable by the evaluating means. The magnet is configured at least as a segment of an annular magnet that is arranged at a second end of the lever and integrated therein.
