D11 Spherical Projector - Moulding

The D/11 spherical transducer provides highly efficient, omni-directional receive and transmit beam patterns. With a resonant frequency of 11 kHz and a useful operating bandwidth from 6 kHz to 20kHz the design is particularly suitable as a broadband noise source or for long range voice and data communications systems. The transducer is extremely robust and able to withstand severe levels of underwater explosive shock. Electrical connection to the transducer is by a twisted pair screened cable. The outer jacket of the cable is extruded polyurethane that enables the transducer to be built into customised equipment packages and readily obtain a waterproof design by simple moulding techniques. The D/11 is available with or without acoustic calibration. All calibrations are traceable to National Standards.
