Product Description


Piezoelectric ceramic tubes

Electrode direction: Radial direction



Applications: underwater acoustic 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.


Piezoelectric tubes, sphere or block/plate was utilized in underwater acoustic transducer/hydrophone, underwater GPS localisation systerm etc.


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 PZT-4 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, Yuhai offer a complete range of three PZT-4 series material types with a variety of permittivity values, coupling, power handling and actuation properties.
