ZMJ60V Series Density Monitors

These instruments are used to monitor the density of SF6 gas in sealed tanks, and can be widely used in medium voltage switchgear, RMU. It's suitable for outdoor harsh external conditions. It can provide multiple solutions to support new substations and the intelligent transformation of existing substations. The electrical maintenance personnel can make SF6 gas density monitor calibration or gas filling without disassembling SF6 density monitor.

Application of ZMJ60V Series Density Monitors


  • Sf6 gas Insulated RMU

  • Sf6 gas Insulated Switchgear


Features of ZMJ60V Series Density Monitors


  • Minimization of volume, custom interface, convenient and reliable installation. 

  • Pressure interface customised to customer requirements. 

  • A plurality of switching contacts according to the needs of the user can be provided. 

  • SF6 gas density monitor can be calibrated or replaced without disassembling an SF6 density monitor. 

  • If the screws are not disassembled, a person can operate independently, which saves effort and time. 

  • On-site staff can be able to measure micro-water and supplement air to a switch 

  • Avoid surface sealing and joint damage caused by disassembly
