  • SF6 Gas Density Switches for High Voltage - Solon MFG

    Temperature-compensated pressure switches automatically adjust their settings to follow temperature changes for all SF6 density levels including mixed gases. SF6 gas density monitors are primarily used to measure the density of SF6 gas in high voltage circuit breakers. Solon manufactures two design styles: Intrinsic and Remote Bulb.

  • Gas density monitors and gas density sensors for SF6 and

    Trafag gas monitoring devices measure the gas density directly, i.e. SF 6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF 6 Gas Density Sensors, or by combining both principles, i.e.SF 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF 6 gas density.

    This results in lower pressure increase in SF6 than in compressed air. The G.I switch gear is so designed that this pressure increase can be accommodated in the circuit breaker with less difficulty. Due to large density of SF 6 the thermal conductivity is also high, the ratio for the same SF6/air is 2.5:1.
