Application of ZMJ80XDR Series Density Monitors

  • 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

Features of ZMJ80XDR Series Density Monitors

  • Using gas compensation, higher set point accuracy

  • Class 1.0  display for full scale

  • Suitable for indoor or outdoor installation

  • Micro switch, can switch freely between normally open and normally closed points

  • Up to four pairs of nodes, 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

  • RS485 bus interface, facilitating system expansion, realizing telemetering and remote control. High anti-electromagnetic interference capability
