Smart SF6 Sensor
Smart SF6 Sensor
NDIR SF6 Sensor 10 years life for SF6 Gas Leakage detection.
- RSS-SF6 is Non Dispersive Infrared (NDIR) gas sensor for ambient air monitoring using dual wavelength technology. Especially designed for the analysis of SF6 leakage, quality and purity inside gas insulated switchgears (GIS).
- RSS-SF6 sensor has long term stability, repeatability and reliable performance and high-precision and easy to calibrate
- Modbus ASCII or RTU data communication offer a variety of options to connect the RSS-SF6 sensor to a controller.
