ABSTRACT:
A device and a method for identifying magnetic induction coordinate comprise a movable member which is provided with a magnetic matter and is moved to pass a plurality of sensors arranged in sequence on a fixed member. As the magnetic matter moves through various positions of a moving track, the sensors detect and measure the magnetic flux values at various positions. The data are recorded point by point by an electronic circuit and are then stored in a memory. The magnetic flux values measured by the sensors at any time are compared with the data stored in the memory for identifying the position of the magnetic matter. As the position of the magnetic matter in relation to the fixed member is identified, an output signal of the position is generated.
