Spectronics Corp. has introduced the Spectroline Marksman ultrasonic diagnostic tool, which converts and amplifies inaudible ultrasonic sound into audible “natural” sound. Aviation technicians can hear sounds that signify problems, such as compressed air, vacuum, pneumatic and other pressurized leaks. It’s also used to check for electrical discharge due to insulation breakdown, carbon tracking and arcing.
The Marksman uses a two-tiered process to ensure accurate diagnosis, according to company officials. 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.
The MDE-1000 Marksman Master Kit comes 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 storage case with foam insert.
