Overview
TR-VS02 is a dedicated very low frequency underwater acoustic transmitter system for long-range underwater communication, marine seismic survey, underwater acoustic testing and calibration. It is composed of a low-frequency underwater transducer and a supporting power amplifier unit.
The transducer delivers stable high source level in 20–1000Hz band, with seawater corrosion resistance up to 1000 hours continuous operation. The matched power amplifier supports 210W max output power, low distortion for high-quality VLF signal excitation. The default working depth is 0–50m, depth rating can be upgraded on request. Standard Seacon MCIL6M marine watertight connector, other interfaces and depth ratings are customizable.
