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精确、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
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
