    AI Overview
    SF6 gas density monitors with stainless steel housings provide robust, hermetically sealed monitoring for high-voltage equipment, with density typically around 6.139 kg/m³ at 20°C and 0.1 MPa. These units often feature temperature compensation, stainless steel wetted parts, and IP65/IP67 protection for outdoor electrical switchgear. 
    Key Features of Stainless Steel SF6 Density Units: 
    • Case Material: AISI 304 or 316 stainless steel, suitable for outdoor or corrosive environments.
    • Accuracy: Typically Class 1.0 or 1.6 at 20°C, and Class 2.5 or 3.0 at lower temperatures (-20°C to +60°C).
    • Wetted Parts: Stainless steel 316/316L, generally with gas-shielded arc welding to ensure high leakage resistance (< 1x10⁻⁹ Pa·m³/s).
    • Compensation: Temperature-compensated bourdon tube or reference chamber technology prevents false alarms due to temperature-induced pressure changes.
    • Switching Contacts: Often equipped with 1 to 3 microswitches to trigger alarms (e.g., low density, lockout). 
    Common Applications: 
    • Medium- and high-voltage Gas Insulated Switchgear (GIS).
    • Outdoor transformers and high-voltage circuit breakers.
    • Ring network cabinets. 
    These monitors are designed to operate accurately across extreme temperatures (-20 ~ +60°C or -30 ~ +60°C) without being affected by altitude or atmospheric pressure changes.

    Is SF6 gas being phased out?
    The regulation sets phase-out dates for the use of SF6 in new circuit breakers and switchgear (provided that SF6-free alternatives are available on the market). The first phase-out date is already January 2026, applying to medium-voltage installations up to and including 24 kV.Dec 8, 2025
