Ultrasonic transducers utilize the piezoelectric effect of piezoelectric ceramics with the same resonant frequency to convert electrical energy into mechanical vibration. Usually, ultrasonic waves are generated by an ultrasonic generator, converted into mechanical vibration by an ultrasonic transducer, and then generated by an ultrasonic export device and an ultrasonic receiving device. Therefore, as an energy converter device, the function of an ultrasonic transducer is to convert the input electrical power into mechanical power (i.e. ultrasonic) and transmit it out, while consuming a small portion of its own power. Our equipment is mainly used for cleaning parts and workpieces.
