The Microsense SF6 Gas Detector

The Microsense IR is a single gas safe area detector for detection of Sulphur Hexafluoride (SF6) that meets the requirements for economic and reliable monitoring of gas levels in applications involving gas-insulated substations (GIS) and high voltage electrical equipment.

The instrument utilises an optical NDIR dual beam Infrared gas sensor technology consisting out of a measurement and reference channel. It’s integrated algorithm compensates for drift and temperature variations.

The unit offers easy access for installation of field wiring and allows for installation close to floor levels, this as SF6 is over 5 times heavier than air. Conclusion: The Microsense IR offers Infrared Technology for an affordable price.
