These magnetic poles are magnetized by a DC exciter coil such that the magnetic poles have opposite polarities. The first magnetic pole is provided at its end surface with a pair of cumulatively connected transmitting coils, and the second magnetic pole is provided at its end surface with a pair of differentially connected receiving coils. The transmitting coils are connected to a pulser which generates a pulse current, and the receiving coils are connected to a differential amplifier. An electromagnetic ultrasonic wave generated by the transmitting coils are received by the receiving coils, amplified by the differential amplifier, and thereafter supplied to a synchroscope and an automatic detector.

摘要： A method and apparatus for detecting the occurrence of rubbing in a rotary machine, in which at least one acoustic sensor is mounted on at least the rotor part or the stator part of the rotary machine, and the output signal from the acoustic sensor is detected and then filtered to extract a frequency component having a frequency substantially equal to the rotational frequency of the rotary machine, so as to detect the occurrence of rubbing in the rotary machine as early as possible and also to locate the source of the rubbing. Even when the occurrence of abnormal metal-to-metal contact at a bearing of the rotary machine is detected, it is discriminated from rubbing so that the occurrence of the rubbing can be reliably detected.
