摘要： Magnetic position sensors are already known which have a resistive track formed on a carrier, a conductive track which is disposed at a distance from the resistive track, and a movably mounted contacting means for producing a local electric connection between the resistive track and the conductive track. The contacting means is a magnet which attracts individual segments of the conductive track toward the resistive track and thus closes the contact to the resistive track. It is disadvantageous that the production costs for the position sensor are comparatively high. In the case of the position sensor according to the invention, the production costs are reduced. The invention provides that the conductive track (5) is configured on an elastic film (12), the contacting means (6) is movably mounted on the elastic film (12) along the conductive track (5) and acts on the conductive track (5) in such a manner that a local contact with the resistive track (2) is produced.

摘要： Proposed is a magnetically passive position sensor (1) comprising a movable magnet, a plurality of contact spring elements (4) arranged in a motion region of the magnet and a resistance device (2). The contact spring elements (4) are spaced opposite the resistance device (2) and can be moved by the magnet to the resistance device (2). The resistance device (2) comprises a plurality of electrical contact surfaces (3) arranged opposite the contact spring elements (4) and arranged separately from each other. Each contact surface (3) is, for example, designed in a U-shape, comprising two limbs (11, 13) made of electrically conductive material, a gap (15) arranged between the limbs (11, 13) without electrically conductive material and a base region (17) made of electrically conductive material, said base region joining the limbs (11, 13). Owing to the U-shaped design of the contact surfaces (3), a potentially expensive electrically conductive material can be saved. In addition, dirt particles can preferably accumulate in the gap (15), where same scarcely affect the function of the position sensor.

摘要： The invention relates to a measuring apparatus (10) for measuring a filling level of a container, which measuring apparatus has a measuring arm (12) with a float element (18) which is designed to change its angular position about a rotation axis (38) depending on the filling level. A magnet element (24) is connected to one end of the measuring arm (12) in a rotationally fixed manner. A magnet-sensitive element (26) is designed to output a measurement signal (27) depending on the angular position of the magnet element (24). The measuring apparatus (10) is characterized in that the measuring arm (12) is mounted in a first bearing (22) and additionally in a second bearing (36), wherein the magnet element (24) is arranged in an intermediate space (34) between the first bearing (22) and the second bearing (36).
