I. Purpose：
The SF6 remote density relay manifold is mainly used to control and monitor the density of SF6 gas in sealed container. Generally used in SF6 high voltage switch, medium voltage switch, gas insulated equipment (GIS), high voltage cable, transformer and mutual inductor, and suitable for outdoor harsh environment. Installed in the equipment make-up gas, micro water port; convenient and fast. The density value of the original mechanical density relay can be transmitted to the terminal of the target equipment, and the SF6 remote density relay valve set is reserved for replenishment. At the same time, the manifold is equipped with safe and reliable circuit transmission function, to realise real-time data remote reading and information monitoring to establish an effective platform. It can transmit pressure, temperature, density and other information to the target equipment in time (usually a computer terminal). The data can be analysed by the target equipment to control the corresponding terminal action.
SF6 remote density relay manifold will transmit valid data to the target equipment through wireless relay in time. The target equipment can read the density and other information of the equipment in real time, the data transmission adopts the wireless receiving method, ensure the integrity and accuracy of the data. The data is reliably and safely transmitted to the equipment terminal, for the terminal equipment to make timely and effective control to lay a solid hardware platform. It will become a powerful tool for electronic monitoring industry.
II. Features：
