The FLIR Si2a-LD (T912646) is a stationary industrial acoustic camera designed for continuous 24/7 monitoring and early detection of compressed air and gas leaks. The system uses 124 low-noise MEMS microphones for real-time sound visualization. AI-powered detection and analysis enable the automatic localization of leaks as well as the estimation of leak size and the resulting annual costs. Thanks to its IP66 protection rating and VESA mounting capability, the camera is suitable for reliable permanent installations in demanding industrial environments outside of potentially explosive atmospheres.
Typical applications include the continuous monitoring of compressed air distribution systems, piping, valves, fittings, and joints. This allows leaks to be detected early on, thereby reducing energy losses and operating costs. In addition, the FLIR Si2a-LD is suitable for the continuous monitoring of gas systems and associated infrastructure to detect, for example, fugitive emissions, pressure-induced leaks, and failing seals before they pose a safety risk. In general, gases under sufficient pressure can be detected; quantification of leakage rates is possible for compressed air, ammonia, argon, carbon dioxide, helium, hydrogen, methane, natural gas, and nitrogen, among others.
