Abstract
In a method for the detection of cavitations in a space to be monitored, the space to be monitored is monitored by means of a sensor (2) which is capable of learning. In this, a state in which cavitations arise in any case in the space to be monitored is first produced during a learning process for the duration of a first time interval (t1). After the completion of the first time interval (t1) a state in which cavitations do not arise in any case in the space to be monitored is produced for the duration of a second time interval (t2). In each of the two time intervals the sensor (2) learns which signals correspond to cavitations and which signals correspond to non-cavitations respectively in the space to be monitored. After the completion of this learning process the sensor compares the signals which arise during operation in the space to be monitored with the learned signals for cavitation and non-cavitation respectively and decides on this basis whether a cavitation has arisen in the space to be monitored or not and produces a corresponding output signal.
