Koreanpiezoelectric tube pzt-4/pzt-8
Piezoelectric tube transducer always be used in areas of acoustics or as liquid transmission medium, to transmit axis non-direction ultrasonic signal or incept axis signal, such as surface ship sonar, equal-float cable, underwater speaker, sonobuoy, underwater , passive sonar array, torpedo, oil well detector, oil well dredge , ultrasonic pipe eliminating dirt, etc.
If adding taper model reflecting cover, axis signal will be changed to radial signal, not only improving coupling impedance, but also advancing sensitivity, so that piezoelectric tube transducer also can be used as gas transmission medium.
