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
a、变送器按照传感器的实际曲线微调其内部的温度曲线，可极大地降低传感器互换性误差（达75%）；644H和644R型智能温度变送器-变送器与传感器比对功能、匹配功能3144和3244MV型智能温度变送器-变送器与传感器匹配功能
b、热电偶测量时，变送器将毫伏信号转换为对噪声较不敏感的4-20mA信号，提高抗干扰的能力，并大大缩短补偿导线的长度；
c、消除热电偶的冷端补偿误差；
 
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
