Overview
TR-VH06 is a spherical integrated 3D vector hydrophone designed for deep-sea low-frequency underwater acoustic measurement. It synchronously acquires three-axis particle velocity and acoustic pressure signals to realize passive bearing estimation of low-frequency sound sources.
Working frequency 15–2000Hz, suitable for deep-sea low-frequency ambient noise monitoring, marine seismic acoustic observation, deep-water target detection and deep-sea acoustic experiments. It maintains stable directional performance with lateral rejection ratio ≥20dB and low asymmetry.
Spherical main body φ170mm, mounting flange φ191mm, air weight 2.9kg, near-neutral buoyancy (1.08g/cm³ in water), which effectively suppresses flow noise during long-term deep-sea deployment. Standard Seacon MCIL12M marine watertight connector, supporting connector, cable and mechanical customization.
