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 insulating gas quantities in indoor air.Get price

Rapid field measurement of ventilation rate using a quartz

May 25, 2020 · The sf6 gassensor was developed by detecting the gas-absorption induced acoustic wave using a tiny quartz tuning fork that is enclosed in a gas cell with a sample volume of 2.5 ml. By locking the QCL wavelength at the absorption peak of Sulfr hexafluoride, we obtained a recording time interval of 0.4 s and a detection limit of 4.6 ppb.Get price
