艾默生推出DL8000新一代预置控制器

2008年01月08日 13:56:00 中国传动网

德州奥斯汀(2008年1月7日)消息,艾默生过程管理有限公司推出基于批量传送控制器之上的DL8000微处理器,用于满足日益增长的高工业标准的精确性和完整性。作为艾默生一级解决方案应用于液体流量测量的成果,DL8000是预置控制器DanLoad生产线的新一代产品,设计用于解决液体输送保管应用的批量控制要求。 工业标准的改变,碳氢化合物产品的高成本,新技术的操作管理成本,就要求测量一定要精确。预置控制器可以将大量的液体精确地传送并装载到卡车、轨车或是船上,在监测关键路线保证安全装载的同时,控制阀门和泵来装载液体。这些过程必须全部满足由API规定的标准,艾默生不断地改进自己的产品以帮助用户保持与API不断更新的测量标准同样的步伐。
由于油价的上涨,其它液体碳氢化合物产品及化学制品在传输数量上的精确测量变得比以往更重要。DL8000的双倍精度数学估算精确性,由艾默生的高特性Fisher®ROC系列摇控操作控制器技术所支持。这不仅要满足API的要求还要提供极精确的测量和可靠本地和远程控制。 由于碳氢化合物的扩增及其在温度和压力方面的变化,将流量测量转化到标准条件下,就需要提供更加精确的测量。DL8000利用平均标准产品的流率,温度、压力和密度,以实现标准情况下的流率测量,这种变换能力节省了数百万美元。 DL8000利用ROCLINK™800软件可以很方便地应用于不同批量的装载应用,并且利用FST或任何由IEC61131-3标准定义的语言实现PLC编程,包括梯形逻辑、结构化文本、功能块图、指令表及顺序功能图语言。DL8000到带有ROConnect的艾默生DeltaV™过程控制系统的连通性可使用户得到最大化的受益,利用艾默生的AMS预测维护软件,可以提高生产力并降低维护成本。 更多关于DL8000和其它来自艾默生过程管理公司的远程自动化解决方案,请登录:www.EmersonProcess.com/Remote .

[font=times]Emerson announces next generation preset controller for batch measurement and control [/font]
[font=times][color=#708090]HOUSTON, TEXAS (January 7, 2008) – Emerson Process Management introduces the DL8000 microprocessor-based batch delivery controller to meet increasingly high industry standards for accuracy and integrity. A result of Emerson’s commitment to deliver best-in-class solutions for liquid flow measurement, DL8000 is the next generation of the DanLoad line of Preset Controllers, designed to resolve batch control requirements for liquid custody transfer applications. Changing industry standards , the high cost of hydrocarbon products, and the need to manage operation costs fuel the new technology. Preset controllers accurately set the amount of liquid to be delivered and loaded into a truck, railcar, or ship, and control the valves and pumps to load the liquid while monitoring critical circuits to ensure safe loading. These processes must all meet standards set by the American Petroleum Institute (API). The API continually updates its measurement standards and Emerson improves its products to help our customers keep in step. With the high price of oil, other liquid hydrocarbon products, and chemicals, precise measurement of delivered quantities for revenue metering is more critical than ever. The accuracy of the DL8000 is enhanced with the capability for double-precision math computations supplied by Emerson‘s high performing Fisher® ROC-Series remote operations controller technology. This not only satisfies API requirements, but also provides extremely accurate measurement and reliable control, local or remote. Because hydrocarbons expand and contract with changes in temperature and pressure, converting the flow measurement to standard conditions provides a more accurate measurement. The DL8000 calculates flow for custody transfer using average measured product flow rates, measured temperature, pressure, and density to achieve a measurement of flow at standard conditions. This conversion capability provides potential savings of million of dollars over time. The DL8000 is easy to configure for different batch loading applications using ROCLINK™ 800 software and is fully programmable for PLC tasks using FST (Function Sequence Tables) or any of the languages defined by IEC Standard 61131-3, including ladder logic, structured text, function block diagrams, instruction list, or sequential function chart language. Connectivity of the DL8000 to Emerson’s DeltaV™ Process Control Systems with ROConnect enables the customer to drive maximum benefit, performing remote device diagnostics using Emerson’s AMS™ Suite predictive maintenance software. This improves productivity and reduces maintenance cost.
