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 calibration. All calibrations are traceable to National Standards.

Broadband Version
The D/26 can be supplied with passive matching networks designed to improve the overall frequency response. The combination of transducer and matching can achieve a 3dB bandwidth from 22 kHz to 42 kHz.
