Bowcome Supply Piezoelectric Generator Ceramic Disc, Ultrasonic Piezoelectric Ceramic Transducers, Piezo Ceramic Element,ultrasonic Piezoelectric Ceramic Transducer,ultrasonic Piezo Transducer Manufacturers Supply Pzt Piezoelectric Ceramic Disc of 1.7mhz/2.4mhz/3mhz, 16mm/20mm/25mm/28mm 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. Excellent Insulation properties
