摘要
The cavitation detection method uses at least 2 directional-selective oscillation measurements provided for at least one pump component in a given frequency range corresponding to structural resonance of the pump component, with provision of a characteristic value indicating the occurrence and/or intensity of the cavitation from the oscillation amplitudes for 2 different spatial directions. The characteristic value can be provided by the quotient of the oscillation amplitudes detected by 2 oscillation sensors (11,12). An Independent claim for a cavitation detection device for a fluid pump is also included.
