SF 6 sensors for gas-insulated switchgears (GIS) . The main area of application for the non-flammable gas sulphur hexafluoride (SF 6) is insulation of electrical high-voltage switchgears, transformers and cables.Although sulphur hexafluoride is non-toxic and non-flammable, its global warming potential is about 24,000 times

SF 6 Air Sensor For monitoring the air of SF 6 indoor plant in permanent operation. 3-026-R115. The device even detects smallest SF 6 concentrations and displays the current measuring values permanently. For the operating personnel it is absolutely necessary to know that no radioactive source is used.

The two new SF 6 sensors of the FLOW EVO series have been specially designed for analysis, leak detection and ambient air monitoring. They are suitable for SF6 gas measurement in the 1000 ppm and 2000 ppm ranges and have been significantly improved in terms of detection limits and linearity compared to earlier versions. smartGAS has optimized the NDIR sensors for use in portable SF 6

Mixtures of SF 6 -N 2 for GIS have several advantages over pure SF 6, primarily the reduced environmental impact [2] but also the lower operational temperatures achievable due to the reduced

Aluminum Oxide sensors usually perform better on very dry gas. Unfortunately the sensor is known for trapping SF6 on its surface, leading to false dry readings. AL203 sensors need to be calibrated more often than others, and should be acclimated to ambient humidity and temperature for a few hours if the sensor hasn’t been used
