MDK Density Switch

These instruments 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 external conditions. They can provide multiple solutions to support new substations and the intelligent transformation of existing substations.

Application

SF6 gas insulated RMU

SF6 gas Insulated Switchgear


Features

Gas compensation ensures higher set point accuracy.

Micro switch enables normally open contacts and normally closed contacts freely switch to each other.  

High shock resistance

Normally closed contacts will not set a false alarm due to vibration
