T170

T170
  • 6 KHZ FREE FLOODED RING BROADBAND
  • HIGH POWER
  • OMNI-DIRECTIONAL BEAM PATTERN
  • UNLIMITED DEPTH
  • LONG RANGE TRANSMISSION

The T170 is one of a range of Free Flooded Ring transducers recently introduced by Neptune. Utilising the latest ceramic technology, the FFR concept is ideally suited for high power, broadband, low frequency sound generation. 

Another advantage of the design is its ability to operate down to full ocean depth at maximum efficiency. 

The T170 is available with or without acoustic calibration which is traceable to National Standards.
