Our Company's Newly Developed LoRa Wireless Remote Transmission Meter Product Release
FXM100/TW Series LoRa Wireless Remote SF6 Gas Density Relay
Description
The FXM100/TW series LoRa wireless remote SF6 gas density relay can achieve LoRa wireless remote transmission function. Full power with SF6 density relay. It can directly indicate the density (P20) value on the dial, which is used to monitor the density (P20) value of SF6 gas in closed containers. When the density (P20) value reaches the set value, the internal contact logic state changes, thereby outputting the contact signal; It also has real-time digital information collection, calculation, and LoRa wireless remote transmission,which can provide real-time data for the online monitoring system of equipment status. Mainly used for SF6 Insulated GIS switchgear, circuit breakers, pole mounted switches, and transformers, as well as SF6 gas online monitoring systems.
