TR-DH-20 Deep-sea Hydrophone (Transducer)
LOW NOISE PERFORMANCE / ACOUSTIC REFERENCE STANDARD/ OMNI BEAM PATTERN / HIGH PERFORMANCE
TR-DH-20 is a compact deep-sea reference hydrophone transducer for precision underwater acoustic receiving. It maintains LOW NOISE PERFORMANCE, uniform OMNI BEAM PATTERN and stable HIGH PERFORMANCE electroacoustic response across the 20 Hz–20 kHz operating bandwidth. It features receiving sensitivity of -192 ±1.5 dB and is pressure-rated for continuous operation at depths up to 6000 meters.
Widely used in underwater communication, countermeasures, positioning, and measurement applications.
It is well suited for deep-sea acoustic metrology and calibration, deep-sea ambient noise monitoring, passive acoustic monitoring (PAM) of marine mammals, and deep-water baseline positioning for AUV and ROV.
