40 kHz ultrasonic signal generator for leak detection and airtightness testing of non-pressurized enclosures using Fluke acoustic imaging cameras.
The Fluke SB140 SoundBeacon is an ultrasonic signal generator designed for leak detection and airtightness testing of non-pressurized containers and enclosed spaces. Used with Fluke acoustic imaging cameras, such as the ii1030 and ii1050, it helps identify leaks through welds, gaskets, seals, doors and windows.
The signal generator is placed inside the enclosure being inspected, where it emits a 40 kHz ultrasonic signal. Any gaps or openings allow the signal to escape, making it possible to visually locate potential leak points from outside using the acoustic imaging camera. The camera's Beacon Mode™ simplifies detection by focusing on the ultrasonic frequency generated by the SB140.
This method enables airtightness testing without pressurizing the enclosure. Typical applications include automotive and aerospace manufacturing, cleanrooms, appliance production, shipping containers and the inspection of doors, windows and building facades.
