在Rosemount X-STREAM®过程气体分析仪中，灵敏度、检测范围、稳定性及校准间隔都有所提高。 艾默生过程管理公司在推出X-STREAM®过程气体分析仪时，推出了其新IntrinzX™内在的光测技术。光测技术提供了高灵敏度、大动态范围和长跨 度稳定性。 加强的X-STREAM分析仪与对环境安全的硬化包装相结合，可方便使用、安装和维护，附加的性能使得在单个外壳中可放置四个测试部件，并与新 IntrinzX技术更好的相结合使用。 艾默生过程管理Rosemount分析部门过程分析仪营销经理Mike Fersky说：“新过程气体分析仪将为用户提供加强的功能。最小化要求的测量信道，可强长跨度稳定性，扩展的校准间隔可节省维护时间和昂贵的校准费 用。” 该具有专利的IntrinzX技术利用分散的电池、双光束光测和参考信号及测量信号的常量对照，实现内在地线性响应。这可以使灵敏度感测范围实现在0 - 10 ppm。跨度漂移每周少于0.5％，动力范围可从0 -200达到50,000 ppm。 艾默生过程分析仪营销经理（欧洲）Bernd Thalmann说：“X-STREAM分析仪扩展的温度适应范围可适用于所有世界区域，还具备清晰的语言信息显示功能。此增强的产品线已投入施工，为高 要求的应用提供优化的性能，并减小安装维护成本。” X-STREAM分析仪利用Rosemount的红外线、紫外线和可视光测，顺磁和电化学氧气及热连接传导性传感器技术进行探测分析。分析仪已经通过验 证，帮助用户调节好过程，用于改善生产率和可靠性。 新X-STREAM分析仪现有四种配置 [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] 由于安装X-STREAM分析仪可受益的行业有：精炼、石化和化学处理、冶金生产、硬化热处理、天然气生产和分配，易燃混合气体的测量、生物技术、垃圾填 埋处理、锅炉烟道气体分析、电厂、过程熔炉和焚化炉。 更多信息请登录：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.
