T198

T198
  • 12 KHZ TRANSDUCER
  • SINGLE NARROW BEAM
  • LOW SIDE LOBE
  • LONG RANGE ECHO SOUNDER
  • TOWED BODY CAPABILITY
  • FULLY OVER-MOULDED
  • (OPTIONAL) DEEP-WATER 1800M VARIANT AVAILABLE

The T198 transducer is a high power, long range directional array operating at 12 kHz. Originally designed for over-side installation, the T198 can also be hull mounted. 

The nodal mounted tonpilz elements are extremely robust, capable of withstanding high slamming forces, highly efficient and provide an excellent front to back ratio. An external transformer can be supplied to accommodate any impedance matching. 

The transducer housing is an over-moulded, robust and corrosion free transducer body. 

The T198 is available with or without acoustic calibration which is traceable to National Standards.
