Versatile Ultrasonic Diagnostic Tool “Hears” Problems Before They Lead to Breakdowns in Aviation Systems

Spectronics Corporation has its pulse on the latest and most advanced leak detection solutions in the aviation industry, and the Spectroline® MDE-2000NC Marksman™II ultrasonic diagnostic tool is one such notable achievement.

When pressurized leaks, component wear and other defects are in their early stages, they create a friction only heard in the ultrasonic range. The Marksman II converts and amplifies inaudible ultrasonic sound into audible “natural” sound. This highly advanced tool allows the aircraft technician to “hear” even the smallest brake, vacuum, tire, and other pressurized leaks before they lead to major breakdowns. The contact probe pinpoints wear or damage to gears, bearings and other internal components without disassembly.

The tool uses a two-tiered approach to ensure accurate diagnosis. The receiver converts inaudible ultrasonic sound into audible sound using heterodyne circuitry. Then, its unique Sound Signature Technology finetunes the audible sound into the natural sound emitted by the leak itself. A 5-LED signal intensity indicator and audible alarm locates the exact source of the problem. An Internal Noise Control (INC) feature safeguards against ambient noise and the Automatic Gain Control (AGC) circuitry automatically adjusts to optimize signal sensitivity during every inspection.

The Marksman II comes complete with an ultrasonic receiver, full-sized, heavy duty, noise-cancelling headphones, a hollow air probe, a solid contact probe and an ultrasonic emitter that helps locate faulty seals, gaskets and weatherstripping in doors, windows, trunks and other non-pressurized enclosures. All components are packed in a sturdy carrying case.
