J100PR REMOTE-TRANSMISSON DENSITY > Description These instruments are used to monitor SF6 gas density in sealed tanks. They are applied to indicate gas density and to provide a signal outputs when the density reaches the set value.They are able to transmit the real-time data of SF6 gas density remotely and achieve the online remote monitoring. They are designed to monitor High Voltage systems. They can provide multiple solutions to support new substations and the intelligent transformation of existing substations. Application SF6 Gas Insulated Switchgear (GIS) SF6 Insulated Circuit Breakers SF6 Insulated Pole-Mounted Switch > Features 1 .The temperature compensation device ensures higher measurement accuracy. 2. Perfect mechanical and electronic combination, local indication and control of instrumentation. The precise mechanical structure enables the real-time remote transmission of electronic signal. 3. RS485 bus interface, facilitating system expansion, realizing telemetering and remote control. High anti-electromagnetic interference capability 4. Suitable for indoor or outdoor installation 5. AISI 304 hermetically sealed stainless steel case 6. Gas connection tubes are made of AISI 316 stainless steel 7. The on-screen display value and output signals are independent of the impact of external environment, such as altitude 8. Up to four switch contacts can achieve overpressure alarm, dual alarm or double locking and many other options, making the monitoring more secure and reliable SF6 Insulated Transformers SF6 Insulated Mutual Inductor SF6 Insulated Busbar Systems > Options 1.
