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.
Application
SF6 Gas Insulated RMU
SF6 Gas Insulated Switchgear
Features
Temperature compensation ensures higher set point accuracy.
Can provide up to three sets of microswitch contacts allowing instant and accurate switching
High shock resistance
Normally closed contacts will not set a false alarm due to vibration
