Fluke SB140 SoundBeacon
The Fluke SB140 SoundBeacon is an ultrasonic transmitter for leak detection and tightness testing in systems where overpressure cannot be applied. It is placed inside the object to be inspected, and together with a Fluke Acoustic Imager, you can then see where the ultrasound escapes. This makes it easier to find leaks in, for example, weld seams, gaskets, joints, hatches, or windows.
It transmits at 40 kHz ± 1.5 kHz, a frequency well-suited for moving through air with low attenuation. In practice, this means the signal can more easily find a leak path and be detected from outside with the right Fluke equipment. This is also why it is well-suited for inspection tasks where a quick and visual method is desired instead of a more time-consuming manual review.
The unit is powered by a 9-volt alkaline battery and has a battery life of more than 300 hours. It comes with a 1-inch probe, soft case, manual, and warranty card. The housing is made of extruded aluminum, and it weighs 175 g with the battery. The protection is IP40, and the operating temperature ranges from -20 °C to +54 °C.

Typical applications
The SB140 is used in tightness testing and leak detection on non-pressurized applications, including in the automotive industry, aviation, trains, cleanrooms, white goods, maritime tasks, and construction. This can be for inspecting cabins, battery compartments, doors, windows, facades, containers, and other enclosed spaces where leaks need to be found quickly and visually.
