D/11/BB Wide-Band Projectors

The D/11/BB is a wide band, highly efficient, omni-directional transmit and receive transducer. With a -3db bandwidth from 8 kHz to 19 kHz the D/11/BB is a high power, long range transducer ideally suited for use in low frequency noise systems, long-range transponder applications and long range voice/data comms systems. The robust, corrosion free construction enables the transducer to operate in extreme underwater environments and withstand high mechanical and explosive shock levels. The over-moulded design enables the D/17/BB to be mechanically robust and suitable for harsh environments. Electrical connection to the transducer is by a 2 core screened polyurethane cable. The D/11/BB is available with or without acoustic calibration. All calibrations are traceable to National Standards.
