Sonel TUD-1 is a compact, portable device that receives ultrasonic waves transmitted by air, and then converts them into acoustic waves in the range audible through the human ear. The device additionally amplifies the received signals. Next after conversion, TUD-1 displays them on the diode bargraph and emits in an acoustic form through the headset.
Sonel TUD-1 is a professional portable device that allows you to do the following:

  • location of sources of electric discharges such as power lines, insulators, generators, transformers;
  • searching for leaks in pneumatic and hydraulic systems;
  • leak check of water and gas supply installations such as pipelines, taps and valves, elements of hydraulic equipment, pumps, compressors;
  • diagnostics of the condition of mechanical system components such as bearings, gears, drive shafts, pumps, compressors, generators.


In cases where tested systems are not filled with a factor, and at the same time there is no leakage detected, the ultrasonic generator GUD-1 is required. It works on a simple bases. It produces sounds that occur during the leakage, making the test safer and lossless. The turned on generator is placed inside the system and then closed. The generated ultrasounds spread throughout the entire installation, leaking in places of damage. Then, using the TUD-1 ultrasonic detector, the operator seeks for sources of signal, which means spots of alleged damage.
The TG-1 contains both devices, which makes it a comprehensive set for leak and electric discharge detection.
