This paper describes a method for predicting the cavitation intensity of hydraulic devices by means of the analysis of recorded pressure signal. Infact, it seems possible to get in detail the behaviour of the observed variable through the determination of some frequencies of the pressure fluctuations produced by flow turbulence and by the cavitation impulses. It has been found that it is possible to define the numerical value of the critical cavitation limit by means of the determination of a global index as the root mean square of the pressure fluctuations and in which way the spectral signal analysis proves this approach.
