Operation Principle
A sinusoidal electrical signal, at ultrasonic frequency (f>20kHz), is delivered by the generator. This signal is applied to the
‘piezoelectric ceramic’ located inside the transducer. Piezoelectric ceramic converts this signal into mechanical vibrations.
These vibrations are at the same ultrasonic frequency as the electrical signal. The mechanical vibrations are propagated
towards the distal end of the transducer. The “TIP” insert, which is attached at the distal end of the transducer, vibrates at
ultrasonic frequencies and makes it possible to achieve the aimed purpose.
