Low Cost 40khz Spherical Transmitting Receiving Transducer for Underwater Communications

Low Cost 40khz Spherical Transmitting Receiving Transducer for Underwater Communications 

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.

Measurement content:

1.1.1.Transmitting voltage response

Measuring the transmitting voltage response within the frequency band of 40kHz to 45kHz, and the response within the frequency band shall not be less than 140dB.

1.2. Receiving sensitivity

Measure the receiving sensitivity in the 40kHz to 45kHz frequency band, and the frequency band shall not be lower than -202dB.

1.3. Horizontal directivity

Omnidirectional, measuring frequency 40kHz.

1.4.Vertical directivity

Not less than 180°, measuring frequency 40kHz.

1.5. Hydrostatic pressure: 2MPa.

hydrostatic pressure test

After the transducer has passed the 2MPa/0.5h, 0MPa/0.25h, 2MPa/0.5h hydrostatic pressure test, the insulation resistance between the positive and negative electrodes of the transducer is greater than 100MΩ.
