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
