SW521 is a SF sensor that adopts NDIR infrared absorption detection principle.6gas sensor. 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 method of this module is diffusion type. Compared with similar products,it has superior performance,good stability and high precision. The measurement range is 0-5000ppm; the resolution can reach 0.6~1ppm. The output modes include RS485 output,UART output,analog voltage output,and analog current output. 9 to 30 volt power supply,76X41X15.
