news.thomasnet.comLa compagnie FLIR Systems avait annoncé la mise en marché d'une caméra qui pouvait détecter en temps réel les fuites de beaucoup de GES. Voici une brève traduction d'une partie du communiqué de presse de la compagnie. La merveille porte le nom de GasFindIR-LW et est en vérité une caméra sophistiquée qui détecte les infra-rouges. Elle est utile à l'EPA et à l'industrie qui veut mieux maîtriser les fuites.
Elle détecte le gaz appelé SF6 (hexafluorure de soufre) à une distance de plusieurs centaines de pieds et fournit des images thermiques à haute résolution qui peuvent être visionnées sur un appareil télé ordinaire ou enregistrées numériquement. En plus du SF6, elle détecte les fuites de chlorure d'acétyle, de bromure d'allyle, de chlorure allylique, de fluorure allylique, de buta-1,3-diène, d'éthylène, de fréon 11, fréon 12, fréon 112, fréon 113, fréon 114, du méthylsilane, du méthylvinylcétone, du méthyl vinyl éther, l'acroléine, du propylène, du styrène, de trichloréthylène, de chlorure de vinyle, du vinyl ether et du fluorure de vinylidène.

Photo: EPABased on a unique, patent-pending technology, FLIR's GasFindIR-LW is a one-of-a-kind infrared camera designed to help the U.S. Environmental Agency and utility companies to better control Sulfur Hexafluoride (SF6) emissions in order to preserve the environment now and for future generations. In addition to the "greenhouse gas" SF6, the versatile GasFindIR-LW can also detect more than 20 other gases floating in the atmosphere.
BOSTON, Massachusetts (April 3, 2007) - FLIR Systems, the global leader in infrared cameras, has announced its latest in ground-breaking infrared technology - the ThermaCAM® GasFindIR-LW infrared camera. Based on a first-of-its-kind, patent-pending technology, the GasFindIR-LW can detect Sulfur Hexafluoride (SF6), the colorless, odorless, nontoxic, and nonflammable "greenhouse gas" that is used as an insulator in high voltage equipment by the electric utility industry. SF6, although considered to be an excellent dielectric gas, has been targeted for emissions reductions by the U.S. Environmental Protection Agency because pound for pound, Sulfur Hexafluoride contributes more to the greenhouse effect than any other gas.
In fact, one pound of SF6 has the same global warming impact of 11 tons of CO2. It has 23,900 times the global warming potential of CO2 and has an atmospheric lifetime of 3,200 years. Together, the EPA and many of the major utilities companies are working to find ways to better control SF6 emissions to help to preserve the earth.
FLIR's revolutionary GasFindIR-LW is lightweight, ergonomic, and easy to operate. It weighs only 4.6 pounds and is powered by a camcorder battery. The GasFindIR-LW enables thermographers to find SF6 gas leaks up to hundreds of feet away quickly and easily. Capable of scanning large areas, the GasFindIR-LW delivers real-time, high resolution thermal images of gas leaks that can be displayed on a standard TV or recorded digitally using the latest real time digital recording technology.
"I believe electric utilities are just as anxious to find these problems as the environmental enforcement community. Until now, they have not had the right tool to quickly localize leaks and assess their severity," said Tom Scanlon, Vice President for FLIR Systems. "Utilities now have that tool and can take the corrective actions necessary to quickly decrease their SF6 emissions."
The unique GasFindIR-LW camera can detect more than 20 other gases in addition to SF6 - making it ideal for not only the utility industry, but for other manufacturing companies as well. These gases include: Acetylchloride, Allyl Bromide, Allyl Chloride, Allyl Fluoride, 1,3-Butadiene, Ethylene, Freon 11, Freon 12, Freon 112, Freon 113, Freon 114, Methylsilane, Methyl Vinyl Ketone, Methyl Vinyl Ether, Propenal, Propene, Styrene, Trichloroethylene, Vinyl Chloride, Vinyl Ether, and Vinylidene Fluoride.
FLIR's GasFindIR-LW camera is expected to be in full production by Summer 2007.
