Abstract: PURPOSE:To surely detect the fault of a revolution sensor even during the stopping time of an automobile so as to improve the reliability of the sensor by providing magnetism sensitive elements in the main bodies of the sensor counterposed on both side of a center rotor and coils for generating magnetic fields around the elements for detecting faults. CONSTITUTION:In order to transmit magnetic fluxes to magnetic reluctance elements 1a and 1b, a magnetic pole 3 is formed in a U-shape and a coil 4 for generating magnetic fields is wound around one leg section of the pole 3. Power supply to the elements 1a and 1b is made through a cable 5 and the outputs of the elements 1a and 1b are lead to the outside through the cable 5. When a rotor 8 rotates, a differential output voltage is generated across the elements 1a and 1b and a voltage signal having the frequency corresponding to the rotating speed of the rotor 8 is outputted. During the stopping time of the rotor 8, no signal is generated, but, when an AC current having a sine waveform is applied to the coil 4, a differential output is generated across the elements 1 similarly to the case where the rotor 8 is rotated. The waveform of the differential output becomes the same as that of the applied voltage when the elements 1 are normal and different when the elements 1 are faulty. Therefore, the fault of this sensor can be detected even during the stopping time of an automobile.
