ge SF6 Air Sensor Calibration with Low-Cost

Aug 30, 2019 · In principle, this device is a flow rate detector, since the sensor is pumping the gas at a constant speed through the electric field. By calibration, this flow rate is internally converted into SF6 concentrations and recorded as ppmv. The photo shows an ECD.

  • NDIR SENSORS FOR SF6 MEASUREMENT

    or reliably detect minute SF6 quantities in indoor air. No matter what SF6 concentration has to be measured under what conditions – smartGAS offers the suitable NDIR sensor. SF6 is the strongest greenhouse gas and therefore the most harmful to the environ-ment. Its global warming potential (GWP) is almost 24,000 times higher than that of CO2.

  • Using Low-cost sensors to Quantify the Effects of Air

    Although many low-cost monitors currently exist on the market, none met our needs with reliable data storage, portability for personal exposure, and well-defined sensor performance. This led us to design our own monitors. Low-cost air monitors used during this project were developed over multiple years by researchers at Duke University.

  • 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
