Piezoelectric Tube for Ultrasonic Receiving Transducer 68KHz

Piezoelectric ceramic tubes   Electrode direction: Radial direction Applications: underwater ultrasonic receiver transducer When the ultrasonic wave propagates, it will reflect when it meets the target. When the echo acts on the crystal of the underwater acoustic transducer, the electrical signals may be obtained on the two ends of the transducer due to the piezoelectric effect. Like radar antenna, underwater acoustic transducer not only transmits and receives ultrasonic signals, but also has sharp directionality. Only in this way can the azimuth of the target be determined. Sonar devices use many piezoelectric crystals to form transducer arrays to achieve sharp directivity. Therefore, the underwater acoustic transducer of sonar is very large, and it is usually installed in the underwater part of the bow of a warship. Transducers are devices that convert sound energy to electricity (or two different forms of energy). Most of the underwater acousti…
