ZMJ60V Density Monitor
ZMJ60V Density Monitors 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 conditions.
It can provide multiple solutions to support new substations and the renovation and upgrading 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 Density Monitor
Feature of ZMJ60V Density Monitor
Compact design, customized installation interface, convenient and reliable.
Process connection customizable in accordance with customer’s demands.
Up to three sets of switching contacts can be provided according to user’s needs.
Without disassembling SF6 density monitor, SF6 gas density monitor can be calibrated or replaced
Without disassembling the screws, a person can operate independently, which is convenient.
Temperature compensation for higher accuracy
It can facilitate on-site personnel to measure micro-water and supplement air for switch
Avoid the sealing surface and sealing joint damage caused by the disassembling
