Fluke SB140 Sound Beacon

The Fluke SB140 Sound Beacon is an ultrasonic sound source designed to work in conjunction with Fluke Acoustic Imagers for detecting leaks and performing tightness testing in both pressurised and non-pressurised environments such as vehicle cabins, aircraft fuselages, cargo containers, cleanrooms and sealed buildings.

During operation, the SB140 is placed inside a sealed space, while a technician uses a Fluke acoustic imager from the outside to detect escaping ultrasound. The SB140 then emits a consistent 40kHz frequency which travels through potential leakage points such as weld seams, seals, hatches, gaskets, and windows, allowing the imager to visually pinpoint the source of the leak. When the imager is set to Beacon Mode, it automatically filters to the frequency of that of the SB140, allowing for fast and highly accurate detection.

The SB140 is easy to use, as it operates with a simple on/off switch and requires minimal training, making it accessible for all personnel. It is powered by a 9V alkaline battery and offers an impressive battery life of over 300 hours. The SB140 is housed in a robust extruded aluminium enclosure, is IP40 rated for ingress protection, can operate in temperatures ranging from of -20°C to +54°C and is backed by a 2-year warranty.

Applications

The Fluke SB140 Sound Beacon is designed to provide easy, fast, and superior leak detection and tightness testing across various industries, helping maintain high-quality standards, reduce warranty claims, and ensure regulatory compliance. For example,

• In the automotive industry, the SB140 reduces warranty claims by performing in-line water leak and tightness tests on auto windows and doors. It ensures safety by verifying the integrity of EV battery compartments with quick and reliable leak testing, and it detects leaks in heavy-duty truck axle compartments to ensure proper sealing.
• In the aviation industry, the SB140 ensures safety by carrying out leak and tightness tests on aircraft cabins, windows, and tanks during both maintenance and production phases.
• In cleanrooms, the SB140 ensures product quality by minimising warranty claims and downtime while meeting regulatory requirements with cleanroom leak and tightness testing.
• On white goods, the SB140 ensures product quality by ensuring proper seals on household appliances such as washing machines and refrigerators properly and conducting efficient in-line leak testing during production.
• In the maritime industry, the SB140 reduces cost by preventing cargo damage and complying with maritime regulations by testing container integrity for leaks and seal effectiveness.
• Finally, in the construction industry, the SB140 ensures quality and efficiency by identifying leakage paths and weak points in doors, windows, façades, and modular office pods, thereby improving energy efficiency and sound insulation.
