SF6 gas sensors for every application
With the SF6 sensors of the FLOWEVO series with measuring ranges of 100 Vol.-%, 2000 ppm, 1000 ppm and 50 ppm smartGAS offers technologies for monitoring SF6 gas quality, SF6 monitoring of room air and SF6 leak detection. The NDIR based FlowEVO SF6 sensor (100 Vol.-%) precisely measure the purity or SF6 gas quality in gas-insulated switchgears, transformers and cables.
The compact NDIR type FlowEVO SF6 sensor (2000 ppm) is typically used in portable gas metres or stationary SF6 leak detectors for checking compliance with the SF6 concentration in the ambient air (MAC = 1000 ppm) of gas-insulated switchgears. Other areas of application are gas reservoirs, power plants and transformer stations, as well as systems for the manufacture of semiconductors.
The compact and lightweight FLOWEVO SF6 sensor (50 ppm) is also installed in portable devices for SF6 gas measurement or stationary SF6 detectors for intermittent or continuous measurement of minuscule SF6 leaks. The high sensitivity and very small lower detection limit enable the 50 ppm sensor to detect even minimal sulphur hexafluoride leaks with absolute reliability.
Another typical application for the highly sensitive FLOWEVO SF6 sensor (50 ppm) is detection of SF6 in environmental simulations. Since sulphur hexafluoride is not present in the atmosphere and non-flammable and non-toxic, it is used in very small concentrations as a tracer gas for real-time analyses of the spreading of fire gases or hazardous substances in tunnels, subways, buildings or ships.
