40kHz-45kHz Spherical Hydrophone Transmitting Receiving Underwater Acoustic Transducer
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.
Measurement results:
After testing, all transducers meet the technical specificati
