The D/17 spherical transducer is a versatile design providing an omni-directional transmit and receive beam pattern.

With a useful operating bandwidth from 10 kHz to 30 kHz and capable of achieving source levels of 203dB it is particularly suitable as a high power noise source or communications transducer. The transducer is extremely robust and able to withstand severe levels of underwater explosive shock.

Electrical connection to the transducer is by a screened twisted pair cable. The outer jacket of the cable is a tough polyurethane material that enables the transducer to be moulded directly into underwater equipment pods or connectors.

As with all Neptune transducers, the D/17 is available with the option of a full acoustic calibration. All calibrations are traceable to National Standards.

Octave Bandwidth Version
A passive matching network is available for the D/17 that improves its transmitting response to achieve a 3dB bandwidth from 10 kHz to 20 kHz.
