Piezo Ceramic Capacitor 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 drilling devices.
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.
Good construction: fastened by bolt, easy for assembling, high reliability.
