  • NDIR SENSORS FOR SF6 MEASUREMENT - smartGAS

    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 SF6File Size: 1MB

  • Rapid field measurement of ventilation rate using a quartz

    May 25, 2020The SF6sensor 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 SF6, we obtained a recording time interval of 0.4 s and a detection limit of 4.6 ppb.
