Highly sensitive hexafluoride leak detection

Highly sensitive hexafluoride leak detection

Mass spectroscopy leak sensors employ helium as the gas target [ 5, 6 ]. These systems have proven to be extremely sensitive, reaching a leak flow detection range of 10 −11 mbar∙l/s, which is suitable for quality control of critical components such as, for example, vehicle airbags or cardiac pacemaker cases. Hydrogen gas can also be used.

  • SF6 Leak Detection Application Note - Advanced Energy

    Direct leak detection in enclosed GIS substation requires highly sensitive and reliable SF 6 gas detection. GIS insulated switchgear require specific operation maintenance procedures to prevent and limit the emissions of the insulating gas (SF 6 – sulfur hexafluoride), which is a very potent greenhouse gas. New regulatory frames like the F-Gas Directive (EC 517/2014) are mandating the use of leak detec-
