SW520 is a SF that adopts NDIR infrared absorption detection principle.6Gas sensor module. It is widely used in the power industry,especially in power equipment,such as high-voltage circuit breakers,transformers,mutual inductors,capacitors,arresters,fuses,etc. SF6The significance of gas sensors is to detect SF in time6Concentration conditions in the current environment to determine whether leakage occurs to avoid SF6Gas decomposes in industrial environments to produce SF4and other toxic gases and other serious consequences.
The ventilation mode of this module is diffusion type,with small size,good stability and fast response. The measurement range is 0~1500ppm,and the range can be customized; the accuracy reaches a resolution of 1~1.5ppm. The output modes include RS485 output (the protocol can be customized) and UART output.
