Products
SW521PPRO is an SF6 gas sensor using the NDIR infrared absorption detection principle. 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. The significance of the SF6 gas sensor is to promptly detect the concentration of SF6 in the current environment in order to determine whether a leak has occurred and to avoid the decomposition of SF6 gas in the industrial environment to produce toxic gases such as SF4 and other serious consequences. Compared with similar products, this module uses a gold-plated cavity, which has superior performance, good stability and high precision. The measurement range is 0-5000ppm; the resolution can reach 1ppm. The output modes include RS485 output, UART output, analog voltage output, and analog current output. 11 to 30 volt power supply, structure size (mm): 80X43X31.
