ABSTRACT:
The present invention relates to a measuring chamber (6) for an ultrasonic bath (1) or for a container which is equipped with a low-frequency ultrasonic source (2) for cavitation generation, this measuring chamber being suitable for determining the cavitation energy via the increase in volume in a measuring liquid (10) contained in the measuring chamber, and the measuring chamber having in addition a container (7) with a sound-permeable window region (8) and a sensor (9) for measuring the increase in volume of the measuring liquid (10).In addition, a method for operating this measuring chamber is presented.With the measuring chamber according to the invention or the corresponding method (independent of a prescribed ultrasonic bath), reliable determination of the introduced ultrasonic power or a conclusion about the cleaning power is possible.
