MDK40 Density Switch

MDK40 Density Switches are used to monitor the density of SF6 gas in sealed tanks, and can be widely used in medium voltage switchgear and RMU. They’re suitable for outdoor harsh environments. They can provide multiple solutions to support new substations and the renovation and smart upgrading of existing substations.
