Full-electronic SF6 Density Monitoring Device
The fully electronic SF6 density monitoring device is used to monitor the density of SF6 gas in a sealed container. It displays the density change trend through a dynamic curve, predicts the gas replenishment time, and has a recovery rate measurement function. When the density value reaches the set value, an electrical contact signal is output. At the same time, data such as density, leakage rate, and early warning signals can be remotely transmitted in real time to achieve the function of online remote monitoring.
Main Features
1. The fully electronic SF6 density monitoring device can dynamically and real - time monitor the pressure, temperature, and density of SF6 gas in the gas chamber.
2. Data curve display for an intuitive understanding of the dynamic trend of the gas chamber.
3. Calculation of leakage rate to predict the gas replenishment time.
4. The fully electronic SF6 density monitoring device has a temperature compensation function and high measurement accuracy.
5. This SF6 density monitoring device has a recovery rate determination function.
6. Data remote transmission via ModBus protocol.
