  • Sulfur Dioxide Gas Detectors | SO2 Detectors | Industrial

    Sulfur Dioxide Gas Detectors (SO2 Detectors) Sulfur dioxide (SO2) is a colorless, extremely toxic gas with a strong odor. Common applications of sulfur dioxide include sulfuric acid production, pulp and paper mills, chemical processing, food and beverage, coking operations and petroleum refineries. Since coal and petroleum often contain sulfur compounds, their combustion will generate SO2 unless the sulfur compounds are removed before the fuel is burned.

  • Switchgear - Wikipedia

    Switchgear for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
