Overview
TR-VH03 is a broadband spherical vector hydrophone designed for low-frequency underwater acoustic measurement. It can simultaneously capture 3D particle velocity and acoustic pressure signals, supporting all-direction passive bearing estimation for low-frequency sound sources.
The working frequency band is 15 Hz-2 kHz, suitable for deep-sea low-frequency noise monitoring, marine seismic acoustic observation and long-range target detection. It has excellent lateral rejection and low directional asymmetry.
Spherical main body Φ135mm, mounting flange Φ156mm, air weight 1.5kg, near-neutral buoyancy (1.06g/cm³ in water), which reduces flow interference. Standard Seacon MCIL12M underwater connector, and alternative connectors can be customized to match deep-sea observation systems.
