Abstract
In this paper we present a method of cavitation detection with miniaturised pressure transducers in rotodynamic pumps. The process is part of a sensor system for pumps and make it possible to detect the operational mode. Cavitation generates surges which are directed by the fluid to the ambiend pipes and casings and hit them. The vibrations at the surface can be measured by accelerators. Thus, the existence of cavitatation is detectable. The idea is now, to detect the cavitation directly by a pressure transducer and use it like a hydrophon. The difference is that pressure transducers already integrated in the pump for pressure measurement, a hydrophon would be an additional element in the system which probably would only be used for this new system functionallity.
