20Hz-10 KHz Low Noise Standard Hydrophone with Preamplifier

20Hz-10 KHz Low Noise Standard Hydrophone with Preamplifier

Technical Parameters

1.Operating Frequency Range

Hydrophone operating frequency range: 0.02 kHz – 16 kHz.

2.Receiving Sensitivity

The receiving sensitivity within the hydrophone's operating frequency range shall be (-161 ± 2) dB (the hydrophone features a built-in preamplifier with a gain of 34 dB for single-ended output and 40 dB for differential output).

3.Hydrostatic Pressure Resistance

The hydrophone shall be capable of withstanding a hydrostatic pressure test of 15 MPa.

Measurement Data

Receiving Sensitivity

Hydrostatic Pressure Test

After undergoing a hydrostatic pressure cycling test at 15 MPa for 8 hours, the hydrophone showed no external damage or abnormalities, and its performance remained normal upon subsequent measurement.

Measurement Results

Testing confirmed that the hydrophone meets the technical specifications.
