▎Product introduction      
     (Sulfur Hexafluoride) SF6 is widely used as insulation and arc-extinguishing medium in high voltage, ultra-high voltage circuit breakers and GIS . The pressure, density, and temperature are key factors to determining insulation and arc-extinguishing performance. The SF6 density online monitoring system is independently developed by our company. This system is mainly designed for real-time monitoring of various high-voltage electrical appliances, such as SF6 gas insulated circuit breakers, GIS , transformers, and other key equipments.

       This system can monitor the gas pressure and temperature of SF6 (sulfur hexafluoride) online. And use wireless data transmission technology to transmit data to the system in real time.

▎Product features

1. Real-time online monitoring of SF6 gas pressure and temperature.

2. Wireless data transmission, the straight-line transmission distance can reach up to 1200 meters.

3. Wireless networking is flexible and can avoid large workload of on-site wiring.

4. Industrial grade design, Reliable in various industrial environments.

5. The system protocol is flexible and compatible in variety of data platforms.

6. The embedded software fully in functions.
