T444

T444
  • 6.5 KHZ BROADBAND PROJECTOR
  • HIGH POWER
  • DIRECTIONAL BEAM PATTERN
  • HIGH PERFORMANCE
  • LONG RANGE TRANSMISSION

The T444 is a single tonpilz transducer offering a high power, broadband performance. With a nominal operating frequency range from 5.5 kHz to 14 kHz transducers can be configured to form half lambda spaced arrays. 

The robust design is tolerant of both dynamic and static pressure making it particularly suitable for both commercial and military applications. 

The T444 is available with or without acoustic calibration which is traceable to National Standards.
