SGE-R100M Series Remote density relaymicro water density


Used to control and monitor the density of SF6 gas in a sealed container. Used in SF6 high voltage circuit breakers, medium voltage switches, gas insulated equipment (GIS), high voltage cables, transformers and transformers, and suitable for strong vibration and outdoor harsh external conditions, can display the SF64 bulk density of SF6 electrical equipment ,and With communication interface, the SF6 body temperature, pressure, density, and micro-water and dew point data in the SF6 electrical equipment can be transmitted to the background by wired or wireless connection. The data can be pushed to the designated user through the self-developed cloud background. The mobile terminal can realize the operation of the SF6 electrical equipment,and the user does not need to go to the site.
