200Hz-600Hz Spherical Transmitting Transducer Underwater Acoustics Transducer

200Hz-600Hz Spherical Transmitting Transducer Underwater Acoustics Transducer

We independently developed acoustic transducer products cover a full range of hydrophones, transmitting transducers, transceiver transducers, sonar array transducers and ultrasonic transducers, covering overflow rings, flextensional and curved discs. and composite materials, etc., achieving full coverage from low to medium frequency to high frequency, from shallow water to 10,000-meter water depth, and can be widely used for listening and homing detection, communication networking, positioning and navigation, seabed surveying and mapping, forward-looking side scanning, industrial and medical ultrasound and other types of acoustic equipment.

Test Report :

1. Measurement content:

1.1.1. Conductance and capacitance curves

Measure the transducer conductance and capacitance curves.

1.2. Send voltage response and sound source level

Measure the voltage response and sound source level sent by the transducer. The measurement frequency band is 200Hz~600Hz. The response at the resonant frequency is not less than 125dB and the sound source level is not less than 180dB.

1.3. Hydrostatic pressure: 0.5MPa.

2. Measurement data

After the transducer has passed the 0.5MPa/0.25h, 0MPa/0.25h, 0.5MPa/0.25h, 0MPa/0.25h hydrostatic pressure test, the insulation resistance between the core wires of the transducer is greater than 200MΩ. The acoustic performance measured after the hydrostatic test is as follows.
