Fluke FLUKE-SB140 6050675 Industrial Acoustic Imager Sound Beacon 40kHz for Leak Detection and Tightness Testing

The Fluke SB140 Sound Beacon transforms leak detection for non-pressurized vessels by working from the inside out, placing an ultrasonic beacon inside sealed containers while acoustic imagers locate escaping sound through weld joints, gaskets, and seals from the outside. This method delivers precise visual leak identification for quality control across automotive, aviation, cleanroom, and construction applications where maintaining vessel integrity is critical.

ULTRASONIC BEACON TECHNOLOGY FOR PRECISE LEAK LOCATION

Operating at 40 kHz ultrasound frequency, the SB140 generates signals that travel effectively through air with minimal attenuation, allowing sound to escape through even small openings where Fluke acoustic imagers can detect and visualize leak points. Compatible acoustic imagers feature beacon mode functionality that simplifies operation, enabling operators to quickly pinpoint problem areas on weld beads, door seals, window gaskets, and hatch closures without pressurizing the system.

EXTENDED RUNTIME AND COMPACT DESIGN

Built with extruded aluminum housing and IP40 protection rating, the SB140 delivers over 300 hours of continuous operation on a single 9-volt alkaline battery. The compact unit weighs 6.2 ounces with battery included and measures 1.26 x 1.26 x 4.125 inches, making it easy to position inside various vessel configurations while withstanding operating temperatures from -20°C to +54°C.

VERSATILE APPLICATIONS ACROSS Trade INDUSTRIES

The SB140 enables tightness testing for automotive battery compartments, aircraft cabin sections, cleanroom environments, appliance seals, cargo containers, and building envelopes without system pressurization. This approach reduces setup time, eliminates pressure-related safety concerns, and provides reliable leak detection for quality assurance programs where maintaining sealed environments directly impacts performance and compliance.

COMPLETE TESTING SOLUTION WITH MINIMAL TRAINING

The SB140 requires minimal operator training and works seamlessly with Fluke acoustic imagers to create a complete leak detection system. Backed by a two-year warranty and compliance with IEC safety standards and FCC regulations, this beacon technology helps maintenance teams identify integrity issues early and maintain system performance standards across critical sealed applications.
