The RESON TC 2122 Transducer is a dual frequency transducer designed for navigation and hydrographic echosounder systems, combining 33 kHz and 200 kHz operating frequencies in a single unit. Built with high-quality piezoceramic elements, it delivers dependable acoustic performance and consistent signal characteristics for professional marine surveying and vessel navigation applications. The unit is compatible with Teledyne RESON SW 60/28/6029 housings as well as Teledyne RESON steel housings, simplifying integration into existing installations.
Engineered for reliable operation in marine environments, the TC 2122 provides conical beam patterns with frequency-specific beam widths and supports substantial transmit power at both operating frequencies. Its PVC housing, PUR-jacketed cable assembly, and specified operating and storage temperature ranges make it suitable for routine deployment in hydrographic and offshore applications. The combination of dual-frequency functionality, defined acoustic characteristics, and housing compatibility makes it a practical solution for echosounder installations requiring proven performance.
