Ultrasonic Transducers

Ultrasonic Transducers 
Piezoelectric transducer uses the piezoelectric effect to realize transducer between electric and sound energy. It comprises a radiation head, electrode, cap, prestressed bolt, piezoelectric transducer is widely used in ultrasonic cleaning machine and high-power industry cleaning devices.

Features
◇ 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 improve 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.
