14kHz Ring Shape Transmitting Transducer for Underwater Field

 Our acoustics team is a self-developed acoustic transducer product covering a full range of hydrophones, transmitting transducers, transceiver transducers, sonar array transducers and ultrasonic transducers, covering overflow rings, bending tension, various types such as curved discs and composite materials have achieved full coverage from medium and low frequencies to high frequencies, from shallow water to 10,000 meters of water depth, and can be widely used in interception and self-guided detection, communications networking, positioning and navigation, seabed surveying and mapping, Forward-looking side scan, industrial and medical ultrasound and other acoustic equipment. It also has strong research and development capabilities in connectors for underwater equipment. The main product series have passed the 8000-meter withstand voltage test and have excellent performance.

Measurement data

 

There are 24 transducers in total. After the transducers are subjected to 5MPa/1h, 0MPa/0.25h, 5MPa/1h, 0MPa/0.25h hydrostatic pressure tests, the insulation resistance between the core wires of the transducers is greater than 200MΩ, and the insulation between the core wires and the shell The resistance is greater than 200MΩ. The acoustic performance was measured after the hydrostatic test as follows.
