20Hz-10 KHz Low Noise Standard Hydrophone with Preamplifier
Product Description
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.
