ZMJ100XD Series Density Monitors

Application of ZMJ100XD Series Density Monitors

  • Gas Insulated Switchgear (GIS)

  • Gas Insulated Lines (GIL)

  • SF6 circuit breakers

  • Gas insulated busbar systems

Features of ZMJ100XD Series Density Monitors

  • Using gas compensation, greater precision of the set point 

  • Class 1.0 full scale display 

  • Indoor or outdoor installation suitable 

  • The micro switch will switch freely between open and closed points. 

  • Up to four node pairs can be realised with several choices, such as double alarms and double locks, making monitoring more safe and efficient 

  • Strong resistance to shock 

  • No need to fill oil, no danger of oil leakage 

  • Normally closed contacts will not falsely alarm due to vibration
