在多變的溫度環境中先進的加強的溫度穩定性可提供過程穩定性 賓夕法尼亞HATFIELD（2007年11月16日）消息，艾默生過程管理有限公司推出具有新特征的Brooks® SLA系列質量流量計和控制器. SLA和智能連接優勢是艾默生杰出的智能數字化熱質量流量平臺應用于Brooks的產品. 這些產品與高級的服務工具相連接，提供S-系列RS-485協議和相似的I/O. SLA還提供了數字總線協議和高級特征的優勢. 新特征可從SLA投資組合中得到. 共面閥選擇項 由于具備新的Brooks共面閥，活塞和孔口被完美的機械化了，以達到合適的預載. 這就允許每一個閥門應以同樣的方法安裝，能夠在很大程度上提改進設備到設備的可重復性，并延伸了質量流量控制器（MFC）量程. 共面閥能提供一些額外的技術優勢. 例如，其提供的典型控制閥可以進行三次控制，可以出現較大的量程，此閥門還能利用較低的斷路電壓來展示低斷路電壓變化所帶來的更好的設備到設備間的可重復性. 高溫度穩定性 由于具備溫度穩定性加強選項，艾默生的每一個Brooks設備在溫度范圍之上都各具特點. 數據在隨后被程序編入設備中，軟件則對由于溫度引起的偏移進行補償. 此結果能顯著改善溫度穩定性規格. 此特征僅SLA系列能夠提供. 零位偏移診斷 艾默生的Brooks產品由于其電阻能達到零位偏移而受到了很長時間的推崇. 艾默生是第一個MFC提供商，并能證明其Brooks設備的穩定性，且具有高級零位偏移診斷選擇的介紹. 此選項介紹性高級的零位偏移診斷選擇項. 此選擇項可以在流量傳感器零位偏移超過用戶指定的限度時，幫助用戶探測并警告用戶. 此獨特的特征在沒有流量的情況下 艾默生的Brooks SLA熱質量流量計，流量控制器和壓力控制器包括： 1 SLA5800系列標準彈性體密封設備. 2 SLAMf系列IP65/NEMA4X耐候性設備 3 SLA7000系列1.125”緊湊的金屬密封和超高純度設備 4 SLA6000系列1.5”金屬密封和UHP設備 關于艾默生過程管理 作為艾默生集團的業務之一，艾默生過程管理為工業生產、加工、分銷提供自動化服務，應用在化工、石油天然氣、精煉、紙漿和造紙、能源、食品飲料、醫藥等領域. 艾默生過程管理將先進的產品和技術結合在為不同工業而設計的工程、咨詢、項目管理和維護服務中. 艾默生過程管理旗下的品牌有：PlantWeb, Micro Motion, Fisher, Rosemount, Mobrey, Daniel, Bristol, DeltaV, Ovation, 以及 AMS 套件. 關于艾默生 總部位于圣路易斯市的艾默生是一家全球領先的公司，該公司將技術與工程相結合，在網絡能源、過程管理、工業自動化、環境優化技術及家電和工具等領域為客戶提供創新性的解決方案. 公司在2006 財年的銷售額達201 億美元. 更多信息：www.Emerson.com. [FONT=times] original text [/FONT] [font=times] Emerson introduces new features on the Brooks® SLA series mass flow meters and controllers [/font] [font=times][Color=#708090]Exclusive enhanced temperature stability option offers process stability in environments with variable temperatures HATFIELD, Pennsylvania （November 16, 2007） – Emerson Process Management has introduced new features on the Brooks® SLA series mass flow meters and controllers. SLA or Smart Link Advantage is Emerson’s premiere smart digital thermal mass flow platform which is featured on Brooks products. These products link to advanced service tools and offer the legacy S-Series RS-485 protocol and analog I/O. SLA also offers the advantage of digital bus protocols and advanced features. Some of the new features available within the SLA portfolio are: Coplanar Valve Option With the new Brooks coplanar valve, the plunger and orifice are machined perfectly to achieve the proper preload. This allows every valve to be assembled the same way which greatly improves device-to-device repeatability and extends the mass flow controller （MFC） turndown. The coplanar valve offers several additional technical advantages. For instance, it provides three times the control range of typical control valves, resulting in larger turndown. The valve also uses less opening voltage and exhibits less opening voltage variation for better device-to-device repeatability. Finally, because there are fewer orifice/restrictor combinations, it reduces spares inventory. Enhanced Temperature Stability With the enhanced temperature stability option, Emerson characterizes every Brooks device over a range of temperatures. The data is then programmed into the device and the software compensates for any drift due to temperature. The result is a dramatically improved temperature stability specification. This feature, offered exclusively on the SLA Series, is critical for ensuring process stability in environments with variable temperatures. Zero Drift Diagnostic Emerson’s Brooks products have long been revered for their resistance to zero drift over long periods of time. Now Emerson is the first MFC supplier to prove the stability of its Brooks devices with the introduction of the exclusive zero drift diagnostic option. This option detects and alerts the user when the flow sensor zero-drifts by more than user specified limits. This unique feature monitors the flow signal during no-flow conditions and then utilizes the device alarms to notify the user when an out of limits condition has been detected. This diagnostic gives the user a higher level of confidence that the process has not shifted. Emerson’s family of Brooks SLA thermal mass flow meters, flow controllers and pressure controllers includes: • SLA5800 Series standard elastomer sealed devices • SLAMf Series IP65 / NEMA4X weatherproof devices • SLA7000 Series 1.125” compact metal sealed and Ultra-High Purity devices • SLA6000 Series 1.5” metal sealed and UHP devices About Emerson Process Management Emerson Process Management （www.emersonprocess.com）, an Emerson business, is a leader in helping businesses automate their production, processing and distribution in the chemical, oil and gas, refining, pulp and paper, power, water and wastewater treatment, food and beverage, life sciences and other industries.
