Industry’s best total performance,a a flexible Coplanar platform,and installed five-year stability,has made the Rosemount 3051 the standard in pressure measurement.
 
Inustry’s best-in-class total performance of ?0.15%
Total performance is the true measure of “real-world”transmitter performance. Using superior sensor technology and engineered for optimal performance,the 3051 delivers unprecedented ?0.04% reference accuracy,resulting in total operating performance of ?0.15%. Superior total performance equates to reduced variability and improved plant safety.
 
带HART协议的罗斯蒙特248温度变送器特点与优势
安装方便。 拆箱后即可安装到过程中为您节省大量成本 
无与伦比的温度监控点性能 
行业标准 DIN B 型 尺寸适合安装在任何连接头上 
可靠的 EMC 性能，符合 NAMUR NE 21 
采用开放的 HART / 4-20 mA 协议进行通信
 
电力行业传统的温度测量方法是采用将热电阻或热电偶通过温度补偿导线直接将电阻和电压信号通过温度卡件连接到控制室.采用这种传统温度测量方法带来的问题:
1． 系统的IO板需要特殊定购
2． 无法通过智能数字信号对仪表进行远程的监视和调整
3． 精度差，输出信号弱，抗干扰能力差
4． 特殊的配线导致安装和检修的困难
 
发电厂2X300MW机组项目中,温度测点参照国外的先进设计,改变了传统直线连接式温度测量方法,温度测点全部采用了罗斯蒙特温度变送器, 共使用了244，248，644共120多台,获得了很大收益:
1.采用标准的4～20mA IO板，节省了采购费用
2.通过HART通讯器，对远方的变送器进行调整和监视，充分发挥了变送器和通讯器的作用，物有所值
3.变送器的高精度，强信号充分的得到了发挥, 解决了干扰的困扰
4.标准的配线减少了采购费，使安装更加方便灵活
 
Features of the Model 248 include:
l Accepts inputs from a wide variety of RTD and thermocouple sensors
l Configuration using HART protocol
l Electronics that are completely encapsulated in epoxy and enclosed in a plastic housing, making the transmitter extremely durable and ensuring long-term reliability
l A compact size and three housing options allowing mounting flexibility in the field
l Assembly including the transmitter,sensor, housing, thermowell, and extension accessories that can be ordered in one model number
