Product details

Product introduction

The HTD-42 Low Noise Hydrophone is designed with a cylindrical shape, and its self noise level is below the local noise of zero level sea conditions. Two cylindrical piezoelectric ceramics can be optionally selected, which can provide horizontal omnidirectional response in the frequency bands of 2Hz~84kHz and 2Hz~200kHz respectively, and support gains of 10, 20, 30, 40, 50, and 60dB by adjusting the amplification factor of the pre-amplifier. After 7 * 24h pressure testing with a pressure of over 40MPa, the product can work normally (i.e. support a maximum working depth of 4000 meters).

Main application scenarios

ü Passive acoustic monitoring

ü Noise measurement, including marine environmental noise measurement and target radiation noise measurement

ü Applied to measuring instruments, it can be used in self-contained hydrophones, sonar buoys, acoustic release devices, underwater acoustic recorders, etc.
