智能温度变送器的研制

Development of an intelligent temperature transmitter

介绍了一种新型温度变送器，它可接收各种常用热电偶输入信号，具有信号调理、线性化、冷端温度自动补偿、模拟、数字输出及远程通讯功能。文章提出了优化系统设计的两种新方法，并对其进行了较详细的分析，最后讨论了系统的抗干扰问题。

This paper introduces a new-typed temperature transmitter,which can receive the input signals from various kinds of common-used thermocouples,and has the functions of signal rectifying,linearizing,cold-end temperature compensation.digital output and remote communication.At the meanwhile,it also presents two new methods to optimize system design,together with a detail analysis.
