NDIR SENSORS FOR Sulfr hexafluoride MEASUREMENT - smartGAS Mikrosensorik

gaz sf6 (sulphur hexafluoride) is a non-com- bustible and non-toxic gas. Throughout the world it is used primarily for insulating electrical high-voltage switching systems, transformers and cables. It is also used as an etching gas in semiconductor produc- tion and as a tracer gas in environmental simulations. The sensors measure either the purity and quality of the insulating gas in the systems or reliably detect minute gaz sf6 quantities in indoor air.Get price

Decomposition of sf6 gas in an RF Plasma Environment

Sulfr hexafluoride clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η Sulfr hexafluoride exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η sf 6 was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W). The addition of oxygen to the reactor re-Get price

New insulating gas sensors for even more precise gas measurement | smartGAS

Jun 14, 2019 · 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 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 leak detectors, but they can also be used in stationary gas detectors.Get price

Plasma etching of Si and SiO2 in gaz sf6–O2 mixtures: Journal of

Jun 04, 1998 · The products of reaction and etch rates of Si and SiO 2 in SF 6 ‐O 2 plasmas have been studied as a function of feed composition in an alumina tube reactor at 27 mHz, 45 W, and 1 Torr. There is a broad chemical analogy with CF 4 ‐0 2 plasmas. As in CF 4 ‐0 2 mixtures, the rate of Si etching and 703.7‐nm emission from electronically excited F atoms each exhibit distinct maxima as a function of feed gas composition; these data support a model in which fluorine atoms, the etchingGet price
