Underwater Transducer Application:


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, piezo cylinder  are ulitized in  underwater acoustic transducer/hydrophone, underwater GPS localisation systerm etc.


Standard Size of Piezo Tube:


Diameter: 5.0 - 100mm
Wall thickness: 1 - 10mm
Height: 2.5 - 50mm
