J1OOPRW WIRELESS TRANSMISSION RE DENSITY > Description These instruments are used to monitor SF6 gas density in sealed tanks. They are applied to indicate the 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 realize the online remote monitoring. They are suitable for monitoring high-pressure system. The SF6 gas density data can be remotely monitored and transmitted by low-power, high anti-interference wireless communication methods. They can provide multiple solutions to support new substations and the intelligent transformation of existing substations. > Application SF6 Gas Insulated Switchgear (GIS) SF6 Insulated Transformers SF6 Insulated Circuit Breakers SF6 Insulated Mutual Inductor SFe Insulated Pole-Mounted Switch SF6 Insulated Busbar Systems > Features 1. The temperature compensation device ensures higher measurement accuracy. 2. Suitable for indoor or outdoor installation 3. AISI 304 hermetically sealed stainless steel case 4. Gas connection tubes are made of AISI 316 stainless steel 5. Wireless communication and convenient for site networking 6. Strong Anti-interference ability and far transmission distance 7. Using concentrator as the center, these instruments can achieve autonomous wireless networking and the concentrator outputs all monitoring data through the RS485. 8. Up to four pairs of contacts can achieve overpressure alarm, dual alarm or double locking and many other options, ensuring the monitoring more secure and reliable > Options 1.
