  • 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

  • A highly sensitive and selective SnS2 monolayer sensor in

    Abstract. A novel 2D material SnS 2 with an appropriate bandgap and high mobility, has been fabricated successfully and shows promising potential in electronic circuits. However, its applications in gas sensing are still poorly studied. In this work, the sensing behavior of SnS 2 monolayer for SF 6 and its five decomposition gases (SO 2 F 2, SOF 2, H 2 S, HF, and SO 2) is investigated by combining density functional theory and nonequilibrium Green’s function.
