  • On Line Monitoring system OLM - HCCONTROL

    Sf6 For measuring of SF6 gas density a special sensor is used. This sensor also can measure the temperature of the gas. The temperature-normalized and the real pressure then can be calculated from this density. Up to three such sensors can be used on each OLM2 Monitors the SF6 leak rate and calculates last date to refill.
