摘要： PURPOSE:To perform precise diagnosis quickly and accurately, by linking a part to be measured having an intrinsic code and a signal analyzing device by a radio means, comparing the detected vibration waveform of the part to be measured with a normal waveform, analyzing and recording the detected vibration waveform when abnormality is judged, and bringing a compact and lightweight device into a rotary machine. CONSTITUTION:Signal converters 12 and 24 on the side of a vibration detector 14 and on the side of a signal analyzing device 26, each provided with a transmitting and receiving part, are linked by a radio means. The inherent code of an object rotary machine 10 is transmitted to the device 26. The device 26 reads the normal waveform corresponding to the code out of a memory, and compares the waveform with the detected vibration waveform from the detector 14. Thus the quality of the machine 10 is judged. When abnormality is judged, the gate of the device 26 is opened, the detected vibration waveform is supplied to the analyzing part, and the amplitude, number of vibration and the like are analyzed and recorded. The result are sent to the converter part 22 and displayed on a display part 22a. In this constitution, the compact and light weight device can be brought into the rotary machine, and the precise diagnosis of the rotating state is performed quickly and accurately.
