发明名称 Arrangement for determining the position of a motion sensor element influencing the formation of a magnetic field of a working magnet along its motion coordinate
摘要 An arrangement can determine the position of a motion sensor element influencing the formation of a magnetic field of a working magnet periodically along its motion co-ordinate. Such an arrangement includes a sensor arrangement, sensitive along a measuring direction aligned parallel to the motion co-ordinate of the motion sensor element. The motion sensor element includes; periodically recurrent areas alternately influencing the measuring field which is being formed parallel to the main surface. The magnetic field of the working magnet is aligned perpendicular to the main surface of the motion sensor element. The sensor arrangement is formed as a magnetoresistive sensor arrangement with at least one half bridge. The arrangement according to the invention provides the possibility of a reliable operation, with a simple structure, also under said conditions and, in connection with a great freedom from interference, it is also quite insensitive to manufacturing tolerances.
