14kHz-20kHz Transducer Spherical Hydrophone for Acoustic Modems
1.Measurement conditions
measuring distance | 1m～3m |
measuring depth | 1m～3m |
2. Measurement content:
Working frequency band: 14kHz～20kHz.
Voltage emission response:
Measure the emission response in the working frequency band, where 16kHz is not less than 143dB; the sound source level is not less than 185dB.
Directivity: horizontal omnidirectional.
Hydrostatic pressure: 4MPa.
3. Measurement data:
Transmit voltage response and sound source level (dB)

Directivity:
Hydrostatic pressure test：
After the transducer has undergone 4MPa/1h, 0MPa/0.25h, 4MPa/1h, 0MPa/0.25 hydrostatic pressure test, the insulation resistance between the positive and negative electrodes of the transducer is greater than 500MΩ.
