在Rosemount X-STREAM®過程氣體分析儀中，靈敏度、檢測范圍、穩定性及校準間隔都有所提高。 艾默生過程管理公司在推出X-STREAM®過程氣體分析儀時，推出了其新IntrinzX™內在的光測技術。光測技術提供了高靈敏度、大動態范圍和長跨 度穩定性。 加強的X-STREAM分析儀與對環境安全的硬化包裝相結合，可方便使用、安裝和維護，附加的性能使得在單個外殼中可放置四個測試部件，并與新 IntrinzX技術更好的相結合使用。 艾默生過程管理Rosemount分析部門過程分析儀營銷經理Mike Fersky說：“新過程氣體分析儀將為用戶提供加強的功能。最小化要求的測量信道，可強長跨度穩定性，擴展的校準間隔可節省維護時間和昂貴的校準費 用。” 該具有專利的IntrinzX技術利用分散的電池、雙光束光測和參考信號及測量信號的常量對照，實現內在地線性響應。這可以使靈敏度感測范圍實現在0 - 10 ppm。跨度漂移每周少于0.5％，動力范圍可從0 -200達到50,000 ppm。 艾默生過程分析儀營銷經理（歐洲）Bernd Thalmann說：“X-STREAM分析儀擴展的溫度適應范圍可適用于所有世界區域，還具備清晰的語言信息顯示功能。此增強的產品線已投入施工，為高 要求的應用提供優化的性能，并減小安裝維護成本。” X-STREAM分析儀利用Rosemount的紅外線、紫外線和可視光測，順磁和電化學氧氣及熱連接傳導性傳感器技術進行探測分析。分析儀已經通過驗 證，幫助用戶調節好過程，用于改善生產率和可靠性。 新X-STREAM分析儀現有四種配置 [font=Arial]• Compact general purpose X-STREAM – half 19-inch rack mountable or tabletop version • General purpose X-STREAM – 19-inch rack mountable or tabletop version • Field housing X-STREAM – NEMA 4X / IP66 version that can be purged/pressurized or non-incendive for installation in hazardous areas • Flameproof X-STREAM – flameproof version that can be installed in Class I, Zone 1, Group IIB + H2 hazardous areas [/font] 由于安裝X-STREAM分析儀可受益的行業有：精煉、石化和化學處理、冶金生產、硬化熱處理、天然氣生產和分配，易燃混合氣體的測量、生物技術、垃圾填 埋處理、鍋爐煙道氣體分析、電廠、過程熔爐和焚化爐。 更多信息請登錄：www.emersonprocess.com/raihome [font=times]original text [/font] [font=times]Emerson‘s new IntrinzX™ photometric technology among enhancements to process gas analyzers [/font] [font=times][color=#708090]Sensitivity, range, stability, and calibration intervals enhanced in Rosemount Analytical X-STREAM® Process Gas Analyzers SOLON, OHIO （June 23, 2008） — Emerson Process Management has unveiled its new IntrinzX™ intrinsically linear photometric technology in the company‘s latest release of X-STREAM® Process Gas Analyzers. The photometric technology provides high-sensitivity, large dynamic ranges, and long-term span stability. The enhanced X-STREAM analyzers combine the environmentally hardened packaging and ease of use, installation and maintenance of the previous version, with the added capability for up to four measurements in a single enclosure along with the benefits of the new IntrinzX technology. "The new process gas analyzers will offer customers heightened performance and functionality," said Mike Fersky, process analyzers marketing manager for the Rosemount Analytical division of Emerson Process Management. "The large dynamic ranges minimize the number of measurement channels required and the long-term span stability will enable extended calibration intervals to save maintenance time and expensive calibration gases." The patent-pending IntrinzX technology uses split cell dual beam photometry and constant comparison of the reference signal and measurement signal to achieve an intrinsically linear response to changes in concentration. This enables sensitivity as low as 0 - 10 ppm, span drift less than 0.5% per week, and dynamic ranges as large as 0 -200 to 50,000 ppm. "X-STREAM analyzers feature extended ambient temperature ranges for all world areas and an alphanumeric display with clear text messages available in multiple languages," said Bernd Thalmann, European process analyzers marketing manager for Emerson. "This enhanced product line is engineered to provide optimal performance in demanding applications, with minimal installation and maintenance costs." X-STREAM analyzers utilize Rosemount Analytical infrared, ultraviolet and visible （NDIR/UV/UVS） photometry, paramagnetic and electrochemical oxygen, and thermal conductivity sensor technologies. The analyzers are field proven to help users fine-tune their processes for increased productivity and profitability. The new X-STREAM analyzers are now available in four configurations: • Compact general purpose X-STREAM – half 19-inch rack mountable or tabletop version • General purpose X-STREAM – 19-inch rack mountable or tabletop version • Field housing X-STREAM – NEMA 4X / IP66 version that can be purged/pressurized or non-incendive for installation in hazardous areas • Flameproof X-STREAM – flameproof version that can be installed in Class I, Zone 1, Group IIB + H2 hazardous areas Industries that can benefit from X-STREAM analyzers include refining, petrochemical and chemical processing, metallurgical production, hardening and heat treatment, natural gas production and distribution, safety measurement for flammable mixtures, biotechnology, landfill applications, and flue gas analysis of boilers, power plants, process furnaces and incinerators.
