Overview
TR-VH05 is a spherical integrated 3D vector hydrophone for 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 offshore low-frequency noise monitoring, marine seismic acoustic observation, shallow-deep sea target detection and underwater acoustic experiments. It features stable directional performance with lateral rejection ≥20dB and low asymmetry.
Spherical main body φ146mm, mounting flange φ156mm, air weight 2kg, near-neutral buoyancy (1.06g/cm³ in water), which effectively suppresses flow noise during long-term underwater deployment. Standard Seacon MCIL12M marine watertight connector, supporting connector, cable and mechanical customization.
