    Advantages of sulphur hexafluoride in gas-insulated switchgears. SF 6 insulation allows safe operation of high- and medium-voltage systems in close areas, since insulation with sulphur hexafluoride requires much smaller safety clearances. Non-dispersive infrared gas sensors (NDIR sensors) from smartGAS are ideal for measuring the SF 6 gas quality and for detecting even very small quantities of the harmful gas.

  • NDIR SENSORS FOR SF6 MEASUREMENT

    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 SF6 quantities in indoor air.

    Audio sensors. Audio Sensors are a component of Transformer anatomy that allows them to hear sounds in their environment. Some are more acute than others, allowing recording of normally inaudible frequencies. Photocells. Photocells are either a component of, or a synonym for optical sensors. They can be shattered in battle, though this appear to be more of an annoyance than a serious injury. Back shoulder sensors. Megatron (in his G2 body) has "back shoulder senses" that allowed him to detect the approaching Starscream. Itunknown how common these sensors are amongst other Transformers. Equilibrium sensors. Equilibrium sensors help a Transformer keep their sense of balance. Isaac Sumdac used this weakness to damage Megatron, calling it his Achilles Heel.
