    摘要: A portalbe apparatus is disclosed for the diagnosis of a rotating machinery utilizing a fast Fourier transform frequency spectrum analysis system. The presence or absence of an abnormality or trouble in the rotating machinery is determined by selecting high amplitudes out from the frequency spectrum computed by the FFT frequency spectrum analysis system, arithmetically processing distribution data of spectrum amplitudes adjacent each frequency giving the corresponding high amplitude, and detecting the amplitude, at which the frequency of vibrations of the rotating machinery has attained a maximum value, together with such frequency. The diagnosis of the rotating machinery with this apparatus can be performed in situ, i.e., at the site of installation of such machinery.
