Fluke SB140 Sound Beacon
Maintain the reliability of your non-pressurized vessels with the Fluke SB140 Sound Beacon. This advanced approach transforms leak detection and tightness testing by positioning the SB140 Sound Beacon within the vessel and utilizing an Acoustic Imager externally to identify escaping ultrasound visually. It efficiently detects leaks through welds, gaskets, seals, hatches, or windows, making it ideal for quality assurance in sectors such as aviation, automotive, railroads, clean rooms, and beyond.

Acoustic Imagers With Beacon Mode
The Fluke SB140 Sound Beacon is specifically crafted for applications requiring precision in detecting tightness and is designed to be used alongside Fluke acoustic imagers. It emits ultrasound at a frequency of 40 kHz, which travels through the air with minimal loss. This enables sound within an enclosed area to escape through a leak pathway and be captured by the camera for visualization. The acoustic imagers are highly sensitive to the SB140’s ultrasound frequency, allowing potential leak locations to be visually displayed on the screen. Using the imager in "Beacon Mode" simplifies the process even further, as the frequency filter is preset and focused on 40 kHz.

Quick And Exact
Ideal for applications where pressurization isn't feasible, offering a swift and precise inspection process for vehicles, aircraft, compartments, and buildings.
Efficient
Traditional methods are slow and labor intensive. The Fluke SB140 Sound Beacon, combined with an acoustic imager, allows you to quickly locate and address leaks.
Simple To Use
Operate easily with minimal training, making it accessible for all personnel.
Applications
Devised to provide simple, quick, and superior leak detection and tightness testing across various industries, the Fluke SB140 Sound Beacon ensures high-quality standards and regulatory compliance.
Areas for Use Include:
Automotive - Window and door seals
Aviation - Aircraft gas tanks, window or door seal, pitot-static system
