all kinds of piezoceramics and piezoelectric ceramic.we can produce according to the required size.
the materials have the pzt4,pzt5 ,pzt8 or other required material.
Ring Shape Piezo Ceramic Plate 24mm 50Khz For Ultrasonic Transducer
24/14/3 Ring Piezoelectric Ceramic:
◊ 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.
widely used in all kinds of ultrasonic sensor.ultrasonic transducer.Medical,ultrasonic detectors and so on
