Hydroacoustics may be one of the most misunderstood techniques for fisheries research. In essence, hydroacoustics monitoring is based on a few relatively simple principles. An acoustic echo sounder transmits a pulse of acoustic energy into the water. The pulse of energy travels through the water at a speed of approximately 1500 m/sec. When the acoustic pulse encounters an object, such as a fish or the bottom,some of the energy (i.e. an echo) is reflected back to the transducer. The echo sounder amplifies the received signal and then sends it to an output device (such as a chart recorder or video display) and digital echo processor.If the signal level exceeds a mark threshold level, a mark appears on the output display device. 

The distance from the top of the display to the mark is proportional to the travel time for the pulse to travel from the transducer to the target and back. Since the velocity in water is known, range (distance from the transducer) can be calculated from this travel time.By displaying the output resulting from many consecutive transmissions, the time “change of range” and direction of objects in the acoustic beam can be monitored.

Application: used for  the ocean project,sonar, hydrophone, hydroacoustic transducers,underwater comunications device,ultrasonic animal repelent, Ultrasonic insect repelent, ultrasonic pest control piezo transducer,displacement of mirror for laser optics by several micrometers and others.

Standard Size of Piezo Tube:

Diameter: 5.0 - 100mm
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.
