The combination of remote density relay and dew point sensor enables on-site collection and processing, while reporting density, pressure, temperature, and micro water content information.

Used for monitoring sealed containersSF₆The density, pressure, temperature, and micro water content of the gas can be displayed on site, and an alarm can be triggered when the density value reaches the set value, with real-time remote transmissionSF₆Gas densityPressure, temperature, micro waterData, realize online remote monitoring function. Suitable for monitoring high-voltage systems, it can provide various solutions such as supporting new substations and intelligent transformation of existing substations.
