10Hz-1000Hz Omnidirectional Spherical Hydrophone Projector Receiving 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.
Specification:
1.Working frequency band
The working frequency band of hydrophone is 10Hz-1000Hz.
2.Receive sensitivity
The receiving sensitivity within the working frequency band of the hydrophone should not be lower than -197dB.
3.Horizontal directivity
For the omnidirectional, its measuring frequency points 20Hz, 500Hz, 1000Hz.
4.horizontal directivity
For greater than 180°, measurement frequency points are 20Hz, 500Hz, and 1000Hz.
5.Resistant to hydrostatic pressure
The hydrophone should be able to withstand the 25Mpa hydrostatic pressure test.

Horizontal Directivity
Hydrostatic Pressure Test
After the hydrophone passed the 25Mpa/0.5h hydrostatic pressure test, the appearance of the hydrophone was not damaged or abnormal. The insulation resistance between the positive and negative electrodes of the hydrophone was greater than 200 megohms, and the insulation resistance between the positive and negative electrodes and the shield was greater than 200 megohms.
Measurement Results
The hydrophone was tested to meet the technical specifications.
