D/26

D/26
  • OMNI-DIRECTIONAL RESPONSE
  • HIGH POWER PROJECTOR
  • EFFICIENT TRANSMITTER
  • BROADBAND OPERATION
  • DEEP WATER CAPABILITY

The D/26 spherical transducer is a versatile design providing omni-directional transmit and receive characteristics over a wide frequency band. 

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. 

The D/26 is available with or without acoustic calibration which is traceable to National Standards.
