D26 Spherical Projector - Moulding

The D/26 spherical transducer is a versatile design providing omni-directional transmit and receive characteristics over a frequency band of 20 kHz to 40 kHz. The all moulded construction coupled with the inherent strength of the PZT ceramic sphere achieves a robust, lightweight and corrosion free design making it the ideal choice as a high power projector. Electrical connection to the transducer is by a screened twisted pair cable with an extruded polyurethane outer jacket. This enables the systems engineer to configure the transducer directly into customised equipment packages using simple moulding techniques. The D/26 is available with or without acoustic calibration. All calibrations are traceable to National Standards.

Wideband Version

Wideband Version A broadband version of this transducer is available (see page 59 & 60 Model D/26/BB). Utilising an internal passive matching network to achieve a 3dB bandwidth from 21 kHz to 44 kHz.
