Piezo Ceramic Disk
Piezo Material: PZT4
Dimensions: 20mm X 2.0mm
Resonant frequency fr: 1 KHz±100 Hz
Piezo ceramic vibrator made of material PZT-4 are used widely in ultrasonic cleaner, ultrasonic welding, ultrasonic distance measure sensor, ultrasonic detector, ultrasonic motor, ultrasonic transformer and other high-power emanant transducers because of the material’s ability of low dielectric lossunder strong voltage and capability stabilization.
