Abstract
PURPOSE: To detect vibrations of machines, apparatus, etc. by detecting the vibrations of objects as frequency changes of acoustic waves or electromagnetic waves.
CONSTITUTION: In case the vibration direction is the same as the acoustic wave advancing direction, the frequency of the reflected acoustic waves becomes low in correspondence to the speeds of the vibrations of a vibrator 10 and in case the vibrating direction is opposite from the acoustic wave advancing direction, the frequency of the reflected acoustic waves increases in correspondence to the speeds of the vibrations of the vibrator 10. The reflected acoustic waves having undergone the frequency modulation are received in the acoustic wave receiver 13 installed to a static system 11 and the voltage signals proportional to the vibrating speeds of the vibrator 10 are obtained. The signals are put in an integrator and a differentiator 16, by which the voltage signals proportional to the amplitude values and accelerations of the respective vibrations are obtained and the vibration supervising of the vibrator 10 is thus accomplished.
