Sulfur Hexafluoride Non-Dispersive Infrared (NDIR)

Shanghai Yixin G7C, 0 – 1500 ppm SF6 range, Modbus RTU + analog output

G7C-IR-SF6 SF6 NDIR Infrared Gas Sensor

The Shanghai Yixin G7C-IR-SF6 is a Non-Dispersive Infrared (NDIR) sensor for sulfur hexafluoride (SF6) detection. It offers a 0 – 1500 ppm range with linearity error of ±30 ppm for ≤600 ppm and ±5% of reading for >600 ppm, a minimum detection limit of 30 ppm and repeatability of ≤3% reading. The sensor provides both Modbus RTU 1200 bps digital output and 0.4 ~ 2 V analog output, powered by 3.3 ~ 6 VDC with average power consumption of only 0.23 W. Its compact size makes system integration easy, ideal for SF6 insulation gas monitoring in electrical equipment, substations, switchgear leakage detection and online monitoring.
