Leakage rate: < 1 x 10~9 Pa m3/s (Helium leakage inspection) 14. Window glass: Laminated safety glass 7. Process connection: M20 x 1.5, (customizable) 15. Weight: 5.5kg 8. Installation method: radial or axial 16. Pressure element: Bourdon tubes Description Remote density monitor and dew point sensor are integrated to achieve in situ collection and processing, and report the density, pressure, temperature and micro-water content information simultaneously. These instruments are used to monitor the density, pressure, temperature and micro-water content of SF6 gas in sealed tanks and able to display the gas density on the site display and to provide a signal outputs when the density value reaches the set value; they can transmit the real-time remote data of SF6 gas density, pressure, temperature and micro-water and achieve the online remote monitoring. They are designed to monitor FIigh 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 SF6 Insulated Transformer SF6 Insulated Transformer 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. The on-site display value and the output signals are not affected by the external environment (altitude factor, etc.) 6. Integrated design for collection device, which can effectively ensure air tightness 7. The collection device occupies only one vent, reducing the risk of leaks 8. Remote-style density monitor and dew point sensor are integrated to achieve in situ collection and processing, and report the density, pressure, temperature and micro-water content information simultaneously 9. Collection devices applies RS485 communication mode, facilitating on-site networking and commissioning 10. All monitoring points within the interval can be interconnected with smart IED or back-end server easily through a dedicated RS485 hub, reducing the number of connecting communication ports, and saving resources Options 1. Withstand voltage: 2.5kV 50/60 Hz 1 min 2. Oil-filled 3. Measuring medium: SF6, Air, N2, SF6 + N2 and other gases Lanso Konly (Shanghai) Instruments Co., Ltd. > Main electrical performance indicators and specifications of the remote transmission part 1.
