ZMJ60XD Density Monitor

These gas density monitors are used to monitor SF6 gas density in sealed tanks. They are applied to indicate the gas density and to provide a signal outputs when the density reaches the set value. They are designed to monitor High Voltage systems. They can provide multiple solutions to support new substations and the intelligent transformation of existing substations.

ZMJ60XD Density Monitor

Application of ZMJ60XD Density Monitor


  • SF6 Gas Insulated Switchgear (GIS)

  • SF6 Insulated Circuit Breakers

  • SF6 Insulated Pole-Mounted Switch

  • SF6 Insulated Transformers

  • SF6 Insulated Mutual Inductor

  • SF6 Insulated Busbar Systems


Feature of ZMJ60XD Density Monitor


  • Gas compensation ensures greater precision of the set point. 

  • Suitable for various indoor and outdoor installation requirements 

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

  • Up to four switch contacts can provide overpressure alarm, dual alarm or double locking, and many other solutions, which ensure secure and more reliable monitoring 

  • High resistance to shock 

  • Without oil, no risk of leakage 

  • Closed contacts normally do not trigger false vibratory alarms
