Flir Si124

The FLIR Si124 is an advanced acoustic imaging system designed to detect and analyse sound sources with exceptional precision. Utilising 124 integrated microphones, it forms a highly accurate acoustic image in the desired direction. This real-time acoustic overlay appears on a digital camera image, allowing users to pinpoint sound origins with remarkable accuracy. It’s an essential tool for locating and classifying partial discharges in high-voltage equipment and detecting pressurised air leaks in industrial environments, even amidst loud background noise. With its ability to provide detailed severity assessments and cost-saving insights, the FLIR Si124 empowers users to address maintenance and operational challenges efficiently.
