Abstract
An operating parameter of a centrifuge is determined by converting vibration of the machine frame of the centrifuge on rotation of the drum thereof to electrical signals having a frequency spectrum which is analyzed. Variations of the peak amplitudes and frequency locations on frequency analysis, e.g. by Fast Fourier Transmissions, is used to signal the parameter, e.g. a parameter representing the degrees of filling the centrifuge, termination of filtration, etc.
