Underwater acoustics Application:

Underwater acoustics is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries. The water may be in the ocean, a lake, a river or a tank. Typical frequencies associated with underwater acoustics are between 10 Hz and 1 MHz. The propagation of sound in the ocean at frequencies lower than 10 Hz is usually not possible without penetrating deep into the seabed, whereas frequencies above 1 MHz are rarely used because they are absorbed very quickly. Underwater acoustics is sometimes known as hydroacoustics.

Wall thickness: 1 - 10mm
Height: 2.5 - 50mm

PZT Material:

 

- PZT-4 is recommended for high power acoustic radiating transducers because of Its high resistance to depolarization and low dielectrIc losses under high electric drive. Its high resistance to depolarization under mechanical stress makes it suitable for use in deep-submersion acoustic transducers and as the active element in electrical power generating systems.

 

- PZT-5A is recommended for hydrophones or instrument applications because of its high resistivity at elevated temperatures, high sensitivity, and high time stability.

 

- PZT-5H has even higher sensitivity and permittivity than PZT-5A, and is in most other respects similar to PZT-5A. Its markedly lower Curie point, however, limits the working temperature range and leads to lower temperature stability. PZT-8 is similar to PZT-4, but has even lower dielectricand mechanical losses under high electric drive.It is recommended for applications requiring higher power handling capability than is suitable for PZT-4.
