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.
 
罗斯蒙特248温度监测装配件设计符合温度监测应用要求。采用HART?协议的该顶部安装变送器可与多种传感器、顶部接线盒和热电偶套管配套订购。所有这些产品均采用能够提供、可靠读数的罗斯蒙特产品设计。
1、提高温度测量的精度/总体性能
2、安装更方便
3、灵活性更大
4、减少安装、维护和运行等的总体费用
 
 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
