ZMJ60XD Density Monitor
ZMJ60XD 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.
Drawing of 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 Current Transformers or Voltage Transformers
SF6 Insulated Busbar Systems
Feature of ZMJ60XD Density Monitor
Higher accuracy from reference chamber temperature compensation technology.
Suitable for indoor or outdoor installation
Micro-switch that can switch freely between normally open and normally closed points
Up to 4 pairs of switches, 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 risk
Normally closed contacts will not falsely alarm due to vibration
