D17 Spherical Projector

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 201dB around resonance 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.
