Conductance and capacitance curves:

Measuring the conductance and capacitance curves of the transducer within the range of 1kHz to 30kHz.

 Transmitting voltage response and sound source level:

Measure the transmission voltage response within the range of 8kHz to 12kHz, where the maximum response is not less than 145dB, the maximum sound source level is not less than 195dB, and the response fluctuation within the frequency band does not exceed 3dB.

Receiving sensitivity:

Measure 8kHz～the receiving sensitivity within 12kHz range, the maximum sensitivity is not less than -190dB.

 Horizontal directivity

Horizontal omnidirectional, measuring frequency points 8kHz, 10kHz, 12kHz.

Vertical directivity

Vertical directivity opening angle, measuring frequency points 8kHz, 10kHz, 12kHz.

Hydrostatic pressure: 20MPa.

Measurement data

There is 1 transducer in total. After the transducer is subjected to 20MPa/0.25h, 0MPa/0.25h, 20MPa/0.25h hydrostatic pressure test, the insulation resistance between the core wires of the transducer is greater than 200MΩ, and the insulation resistance between the core wire and the shell is greater than 200MΩ . The acoustic performance was measured after the hydrostatic test as follows.
