30mm 13pF Piezoelectric Ceramic Disc High Frequency Ultrasonic Crystal Disc Transducer
Piezoelectronic disc 30mm 13pF high capacitance high frequency ultrasonic crystal disc transducer
Piezoelectric Ceramics (PZT) materials are categorized as functional ceramics. In sensors they make it possible toconvert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers and actuators they convert electric voltages into vibrations or deformations.PiezoelectricCeramics materials are classified according to their chemical composition on the one hand, and by the specific application conditions on the other.
