Abstract (en)
[origin: EP0943805A1] The detection method is carried out using a learning sensor (2) for detecting cavitations in a pump chamber (120) due to rotation of an impeller (12). In two intervals (t1, t2) the sensor learns which signals correspond to cavitations and which correspond to non cavitations. Following the termination of the learning operation. The sensor following the learning operation, decides on the basis of specified criteria, whether in the chamber (120) being monitored, a cavitation exists or not exists, and produces a corresponding output signal.
