Piezoelectric ceramic tubes 

Electrode direction: Radial direction



Applications: underwater ultrasonic receiver transducer


Transmitting transducer refers to "transmitter", which is used to emit sound waves in water. It needs to be able to withstand enough power, has high electro-acoustic conversion efficiency and mechanical strength. It usually works in a suitable wide frequency range near the resonance frequency.


Normally piezo ceramic components used in underwater acoustic transducer/hydrophone is piezo tubes, piezo sphere or piezo  Trapezoid strip.



Material:  Pzt-4d


This material range is ideally suited for ultrasonic cleaning, sonar, and other high power acoustic radiation applications. These materials are designated as PZT400 series type materials and are capable of producing large mechanical drive amplitudes while maintaining low mechanical and dielectric losses. In addition, it can be used under both constant and repetitive conditions. Within this group of materials, CeramTec offer a complete range of three PZT400 series material types with a variety of permittivity values, coupling, power handling and actuation properties.
