POSITION CONTROLLER, PARTICULARLY FOR A TRANSLATORY OR ROTARY MOVEMEMENT

摘要

The invention relates to a position controller, particularly for a translatory or rotary movement. A magnet which is connected to an actuator is used as a position transmitter and at least one magnetoresistive sensor is provided. According to the invention, the position transmitter has a high degree of measuring accuracy and is extremely robust, being protected against every kind of environmental influence. The position controller (1), particularly for a translatory or rotary movement, is thus provided with a number of sensors (5.1a) which are arranged in a row. The magnet embodied as a permanent magnet and connected to the actuator (3) can be positioned parallel to the row arrangement of sensors (5.la) and in the vicinity thereof. The permanent magnet (4) can be displaced in a relative manner along the sensors (5.1 a). The sensors (5.1 a) are operated in a saturation mode and measure the directional angle of the detected magnetic field of the permanent magnet (4). The sensors (5.1a), which are connected to a requisite evaluation electronic system, are cast in a single-pieced housing unit (5.1).
