Piezoelectric Ceramic Materials are categorized as functional ceramics. In sensors they make it possible toconvert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers and actuators they convert electric voltages into vibrations or deformations.PiezoelectricCeramics materials are classified according to their chemical composition on the one hand, and by the specific application conditions on the other.

Piezoelectric transducer uses the piezoelectric effect to realize transduction between electric and sound energy. It comprises a radiation head, electrode, cap, prestressed bolt, piezoelectric chip and an insulating tube. The piezoelectric transducer is widely used in ultrasonic cleaning machine and high-power industry welding and drillingdevices.
◊ High efficiency: high mechanical parameter Q, the transduction efficient between electricity and sound above 95%.
◊ High amplitude: the transducer strength is improved by fixing the high speed vibrator directly on the base of washing groove with bolt. Compare with a magnetic expansion vibrator, its amplitude can be improved above 50%.
◊ Good heat resistance: a large range of working temperature, low resonance impedance and heat productivity.
