Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To obtain an accurate signal corresponding to the position of a moving magnetic substance in an every temperature range by AC-coupling-processing the output of a magnetic detecting element, in a device for detecting revolution information, etc., by the change of an applied magnetic field. SOLUTION: With a specified space from a magnetic rotor 2 having at least a protrusion and a recession, a giant magnetoresistance(GMR) element for example is arranged as a magnetic detecting element. A magnetic field is given to the GMR element by magnets 4, and the magnetic field changes and the resistance of a magnetic resistance pattern which the GMR element has changes, if the rotor 2 rotates. This resistance value change is processed by a processing means composed of AC coupling circuit 20, etc., and an output 15 is obtained. When the temperature of the GMR element changes, an output difference is produced in a differential amplifier circuit 12 because of the temperature coefficient of the element. But it becomes possible to obtain a signal which corresponds accurately to the recession and protrusion of the rotor 2, by processing and removing the DC component by the circuit 20.
