Smart SF6 Sensor

NDIR SF6 Sensor 10 years life for SF6 Gas Leakage detection.

Smart SF6 Sensor

5/5

SFS — SF6 Non-Dispersive Infrared (NDIR) gas sensor for ambient air monitoring, using dual-wavelength technology. Designed for gas insulated switchgear (GIS) internal SF6 leakage, quality and purity analysis.

RSS-SF6 sensor has the characteristics of long-term stability, good repeatability, reliable performance, high precision, easy calibration and so on

Modbus ASCII or RTU data communications provide a variety of options for connecting RSS-SF6 sensors to controllers
