RESON Dual-Frequency Echosounder Transducers

The Teledyne RESON TC2122 and TC2178 are dual-frequency transducers with resonant frequencies of 33 and 200 kHz. Both use piezoceramic elements, conical beam shapes, and PVC housings, and are intended for navigation and hydrographic echosounders. Both have a 30 m operating depth and 50 m survival depth.

  • TC2122: 22° ±2° beam width at 33 kHz and 9.1° ±1° at 200 kHz. 5 kg in air with a 33 m cable. Fits RESON SW 60/28/6029 and RESON steel housings.
  • TC2178: Hydrodynamic configuration with 22° ±2° beam width at 33 kHz and 9.5° ±1° at 200 kHz. 9.7 kg in air with an 18 m cable.
