ZMJ100XD Density Monitor
ZMJ100XD Density Monitors are used to monitor SF6 gas density in sealed tanks. They are applied to indicate the gas density and to provide signal outputs when the density reaches the set values. They are designed to monitor High Voltage systems. They can provide multiple solutions to support new substations and the renovation and upgrading of existing substations
Application of ZMJ100XD Series Density Monitors
SF6 Gas Insulated Switchgear (GIS)
SF6 Insulated Circuit Breakers
SF6 Insulated Pole-Mounted Switch
SF6 Insulated Transformers
SF6 Insulated Current Transformers or Voltage Transformers
SF6 Insulated Busbar Systems
Features of ZMJ100XD Series Density Monitors
Higher accuracy from reference chamber temperature compensation technology
Class 1.0 display accuracy for full scale range
Suitable for indoor or outdoor installation
More accurate gauge indication values and contact switching values throughout the temperature range
Micro-switch that can switch freely between normally open and normally closed points
Up to 4 sets of switch contacts, multiple options such as double alarms and double locks can be realized, making monitoring more secure and reliable
High shock resistance. No need to fill oil, no oil leakage hazard
Normally closed contacts will not falsely alarm due to vibration
