Abstract
An Ultrasonic Piezoelectric Transducer for atomizing fluids oscillates at its free natural vibration in a parallel resonant circuit. Very short energy pulses are transmitted into the parallel resonant circuit to maintain continuously the free vibration. The measuring the time dependant voltage of the transducer, the transducer vibration frequency is tapped off to regulate the supplied pulses and to transmit them in proper phases. Thus, optimal atomizing is guaranteed in spite of changing operating conditions.
