FIELD: measurement technology. SUBSTANCE: invention refers to determination of parameters of vibrations of rotating rotor of predominantly high-speed centrifuge, parameters of centrifuge and defects in its units. In correspondence with method frequency, amplitude and form of vibrations are found from frequency spectrum of transmitter, for instance, speed transmitter by values of side bands caused by modulation of basic signal with frequency of vibrations of rotor. Method is characterized by simplified technology of determination of amplitudes and form of vibrations of rotor of centrifuge. EFFECT: increased measurement sensitivity. 2 cl, 3 cl
