Abstract: A path sensor includes at least one electromagnetic converter element (5; 15) and a magnetic circuit having at least one conductance piece (2, 3, 4; 12, 13, 14) and at least one magnet (6; 11). By movement of an element, an effect of the magnetic flux that is measurable by the at least one converter element (5; 15) is effected. The conductance pieces (2, 3, 4; 12, 13) and the converter element (5; 15) are disposed in unchanged positions relative to one another during the path measurement, and a change of a magnetic field that is determinable by the converter element (5; 15) is effected by a movement of the magnet (6; 11) into the measured field. The magnet (6; 11) is polarized in a direction of the measured path (7; 10) in a predetermined area (8; 16) for beginning of an immersion into the measured field, as opposed to adjoining area (9; 17).

Abstract: A path sensor includes at least one electromagnetic converter element and a magnetic circuit having at least one conductance piece (3, 4; 9, 10; 15, 16; 17, 18; 22, 23) and at least one magnet (2; 7, 8; 14; 20, 21). By movement of an element, an effect of the magnetic flux measurable by the converter element is affected. All parts of the magnetic circuit are immovable relative to one another during the path measurement, and the magnetic circuit and the converter element are moveable relative to one another. A change of the magnetic field plottable by the converter element is affected by a change of the air gap (d) in the magnetic circuit during the movement, and the conductance pieces of the magnetic circuit have a shape that conforms to the trajectory of the converter element, so that based on a change of the width (d) of the air gap in the trajectory (5; 6; 13), a predeterminable signal in the converter element is provided.
