ge SF6 Air Sensor detection system for transformers

The infrared sensor measures SF6 in the ppm range so the transmitter can detect a leak in time. It also makes it easier for you to comply with occupational exposure limits. Connect the SF6 transmitter via an analogue or digital interface with a Dräger control unit to a gas warning system. This warns you early on exceeding the preset alarm values.

  • SF6 Monitoring System for GIS – GE Grid Solutions

    SF 6 Monitoring System for GIS. With worldwide scrutiny on SF 6 gas usage, increased environmental reporting requirements and even possible penalties, precise early detection of small gas leaks in Gas Insulated Substations that use so much SF 6 is essential. The B Watch uses the latest generation of EMC resistant digital gas sensors to continuously measure gas pressure and temperatures in order to track changes in density and detect gas leaks down to 0.1% per year.

  • SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS

    The compact NDIR type Flow EVO SF 6 sensor (2000 ppm) is typically used in portable gas metres or stationary SF 6 leak detectors for checking compliance with the SF 6 concentration in the ambient air (MAC = 1000 ppm) of gas-insulated switchgears. Other areas of application are gas reservoirs, power plants and transformer stations, as well as systems for the manufacture of semiconductors.

  • 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.
