Underwater Accoustic Application:
A wide range of underwater acoustic systems, for i.e. ultra low noise hydrophones, which are suitable both for oceanographic research and environmental monitoring.
Hydrophones - most of which are made from piezoelectric ceramics - can also be used to detect subsea leaks and to measure the quality and intensity of sounds produced by human activities in the sea.
Standard Size of Piezo Tube:
Diameter: 5.0 - 100mm
Wall thickness: 1 - 10mm
Height: 2.5 - 50mm
Typical value of "Soft" PZT materials performance:
