  • SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS

    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 FLOW EVO SF 6 sensor (50 ppm) is detection of SF 6 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

  • Highly sensitive photoacoustic multicomponent gas sensor for

    Abstract: A ppb-level photoacoustic multicomponent gas sensor system for sulfur hexafluoride (SF6) decomposition detection was developed by the use of two near-infrared (NIR) diode lasers and an ultraviolet (UV) solid-state laser. A telecommunication fiber amplifier module was used to boost up the excitation optical power from the two NIR lasers.
