德州奥斯汀（2007年7月16日消息）——艾默生过程管理公司已经扩展其测量仪器，推出Rosemount 3100系列超声变送器。新系列所涉及的范围在简易安装和配置包装方面可提供Rosemount可靠性和智能预测性。3100系列变送器是液位槽和露天应用中用于监测液位的理想选择。
在3100中的非接触传感器是由惯性气体制造的，提供高级抗腐蚀性和低维修需求。完整的或遥远的嵌入式传感器在槽体中的温度改变可以自动修正，否则会导致不准确的信息。
可得到的图案或是法兰连接使其适合于化学，油气，电力，水力和水处理工业。变送器安装简易，由于其一些预排序规律和计量表，所以很容易配置。来自3100的诊断信息可以通过使用艾默生的AMS™ Suite软件获取，或使用任意HART®通讯工具如375现场交流器。这些工具或是本地操作界面都可以配置变送器。
变送器可以与墙板嵌入控制装置中的3490系列连接，提供动力和全面的控制选项。变送器可从两个完整的断电器上获得，增加本地控制功能还可以提供高低级警报。
三个新变送器包括3101，3102和3105，3101是设计用于需要4-20 mA输出的节约性液面测量，3102包括HART通讯和完整继电器，3105是经鉴定的安全的可以在露天通道中用于测量距离，水位或计算体积和流速的变送器。
艾默生新 Rosemount3100系列超声变送器
增加在艾默生仪器组合包中的新Rosemount超声变送器，包括基于五种不同测量技术不同压力的非接触雷达，波位导向雷达，超声波和振动叉。
Rosemount 3100系列超声变送器是艾默生智能化，数字化现场设备中的一部分，其增强了PlantWeb®数字化工厂架构，使工厂效率提高2％，更多地传送资产优化，过程自动化和执行管理信息。 original text
Emerson introduces new Rosemount® ultrasonic level transmitters
Non-contacting transmitters provide a fit-and-forget solution for a wide range of continuous level monitoring applications
AUSTIN, TEXAS （July 16, 2007） – Emerson Process Management has expanded its extensive range of level measurement instrumentation with the introduction of the Rosemount 3100 Series Ultrasonic level transmitters. The new range offers Rosemount reliability and predictive intelligence in an easy to install and configure package. The 3100 Series transmitters are ideally suited for monitoring liquid level in tanks and open air applications where long maintenance intervals are a key requisite.
The non-contact sensor in the 3100 is made from an inert material offering superior corrosion resistance and low maintenance requirements. The integral or remote mounted temperature sensor enables automatic corrections where temperature changes in the tank free space could otherwise result in an inaccurate reading.
Available with threaded or flanged connections and suitable for the chemical, oil and gas, power, water and wastewater industries, the transmitters are easy to install and also, thanks to several pre-programmed laws and strapping tables, easy to configure. Diagnostic information from the 3100 can be captured by using Emerson‘s AMS™ Suite software, or by using any other HART® communications tool such as the 375 Field Communicator. These tools, or the local operator interface, can also be used to configure the transmitter.
The transmitters can be combined with the Rosemount 3490 Series of wall and panel mounted control units, providing power and comprehensive control options. The transmitter is available with two integral relays, adding to the local control functionality and can also provide both high and low level alarms.
The three new transmitters include the 3101, designed for use where an economical liquid level measurement is required with a 4-20 mA output; the 3102 which includes HART communications and integral relays; and the 3105 which is certified intrinsically safe and can be used to measure distance, level, or calculate volume or flow in an open channel.
These new Rosemount ultrasonic transmitters add to the Emerson portfolio of level instrumentation that includes transmitters based on five different measurement technologies - differential pressure, non-contacting radar, guided wave radar, ultrasonics, and vibrating fork.
Rosemount 3100 Series Ultrasonic transmitters are part of Emerson‘s broad range of intelligent, digital field devices that power the PlantWeb® digital plant architecture to improve plant efficiency by 2% and more through delivering asset optimisation, process automation, and management execution.
