FSIModel HMS-AT650 -Underwater Transducer

SHARE

The HMS-650 is a very rugged, high power, underwater transducer specifically designed for marine sub-bottom profilers and echo-sounders. The transducer is designed to operate in the 200Hz to 2kHz frequency range. The transducer is suitable for operation in a variety of array configurations to support shallow water sub-bottom profiling applications. Single transducers can support up to 3000W power levels at a 30% duty though this will be cavitation limited depending on the depth of operation.
