Abstract

An ultrasonic transducer, preferably for combating microorganisms in a liquid, comprising at least one at least substantially disc-shaped piezoelectric crystal and at least two resonance masses provided in axial direction on either side of the piezoelectric crystal, wherein the transducer is further provided with sealing means accommodated between the resonance masses and wherein the resonance masses and the sealing means constitute a watertight housing.
