Abstract

PURPOSE:To eliminate the effect of the magnetic field deflection of the moving body itself and accurately measure the advancing direction of the moving body by adequately determining the values of the resistance connected between the input and output terminals of two amplifiers connecting to magnetic sensors. CONSTITUTION:Output windings 10C, 11C are wound to a magnetic core 1C applied with energizing windings in such a manner that they include the opposing body part and intersect perpendicularly to each other. As a result, AC voltages EA, EB generate respectively in the output terminals 10CT, 11CT of the windings 10C, 11C. These voltages EA, EB are amplified by amplifier circuits 30, 31 respectively and the voltages VA, VB are obtained in output terminals 10CT, 11CT via resistances 40, 41, respectively. Here, the resistance values of the resistances 40, 41 are defined as R1, R2 respectively, and the value of R2/R1 is so set as to compensate the magnetic deflection in the moving body. Thereby, the effect of the magnetic field deflection by the moving body itself is eliminated.
