FCP:Flextensional Cylinder Transducer

FCP(Flextional Cylinder Transducer) has fundamental resonance frequency at 136Hz and is most suitable for underwater long range applications where high acoustic power is required at low frequency. The polyurethane body and Stainless steel cover makes its best to be used in sea water for long period of time.

Main Feature

Low Frequency Acoustic Source

Horizontally omni-directional

Longer Range

Can be used as projector at depths of 10m or greater to ensure a sufficient amount of pressure is placed on the transducer due to the flextensional motion

Reliable, robust, high performance, low frequency transducers


High power low frequency acoustic source

Ranging Applications

Sound Navigation

Calibration Standard
