Frankstar Underwater Acoustic Sensors – Overview

Frankstar Technology Group designs high‑performance hydrophones and vector sensors for marine research, defence, and environmental monitoring. Our three core series cover every need:

• DSEN Series – High‑sensitivity models with depth ratings up to 6,000 m and frequency ranges from 1 Hz to 170 kHz. Ideal for deep‑sea arrays, gliders, and buoys.
• UBWS Series – Ultra‑broadband spherical hydrophones from 1 Hz to 250 kHz, rated for 500 m. Perfect for shallow‑water full‑spectrum analysis and omnidirectional reception.
• VDCT Series – 2D and 3D vector hydrophones (50 Hz – 1 kHz) that capture sound pressure and particle velocity for precise direction‑finding and target localisation.

All feature low‑noise preamplifiers, titanium alloy housings, corrosion‑resistant encapsulation, and flexible output options. Trusted worldwide for acoustic measurement, biological monitoring, deep‑sea exploration, and underwater engineering.
