"Hear" Aircraft Problems Before They Become Breakdowns

Aviation technicians can hear sounds that signify problems such as compressed air, vacuum, pneumatic and other pressurized leaks.


Westbury, New York—Spectronics Corporation has introduced the Spectroline® Marksman™ ultrasonic diagnostic tool, a highly accurate instrument that converts and amplifies inaudible ultrasonic sound into audible "natural" sound. Now, aviation technicians can easily hear sounds that signify problems such as compressed air, vacuum, pneumatic and other pressurized leaks. It’s also great for checking electrical discharge due to insulation breakdown, carbon tracking and arcing.

The Marksman uses a two-tiered process to ensure accurate diagnosis. First, the receiver unit converts inaudible sound into audible sound using a process known as heterodyning. Then, the receiver’s Sound Signal Technology™ fine-tunes the audible sound into the natural sound emitted by the defect itself. A 10-bar LED display indicates the intensity of incoming signals.

Designed for optimal performance, the MDE-1000 Marksman Master Kit comes complete with a receiver, full-sized headphones, two probes, and an ultrasonic emitter that allows technicians to test for faulty seals, gaskets and weather stripping in doors, windows, ductwork and other non-pressurized enclosures. When attached to the receiver, the 12-inch hollow probe accentuates air sounds, while the solid contact probe accentuates sounds of worn or grinding gears. Standard 9-volt alkaline batteries are included for both the receiver and the emitter. All components are packed in a sturdy storage case with foam insert.
