Commercial ultrasonic baths employ piezoelectric ceramic to generate cavitation. These ceramics vibrate with large amplitudes and their physical characteristics may be changed decreasing of the performance due to the heating. We develop an experimental study to evaluate the changes in the Butterworth-Van Dyke equivalent electric circuit of a piezoelectric disk caused by the temperature at range from 30 °C to 90 °C, typical of the commercial ultrasonic baths. The results show that motional resistance is significantly modified increasing the mechanical loss. The evaluation of the temperature effects suggests that is not need to use electronic circuits in these systems as resonance tracking.
