ZMJ100P Density Monitor

ZMJ100P Density Monitors are used to monitor SF6 gas density in sealed tanks. They are applied to indicate gas density and to provide signal outputs when the density reaches preset threshold 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.

ZMJ100P Density Monitor


Application of ZMJ100P Gas Density Monitor


  • 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


Feature of ZMJ100P Gas Density Monitor


  • With temperature compensation, ensuring higher measuring accuracy

  • Suitable for indoor or outdoor installation

  • AISI 304 hermetically sealed stainless steel case

  • Gas line connecting parts are made of AISI 316 stainless steel

  • The on-screen display value and output signals are immune from the impact of external environment, such as altitude

  • Electric contact switch design can ensure the precise and stable SF6 gas density monitoring

  • Up to 4 sets of switch contacts can achieve over-pressure alarm, dual alarm or double locking and many other options, making the monitoring more secure and reliable.
