基于PXIe系列数据采集卡的热电偶接线检查方法分析

摘要

介绍了热工水力实验热电偶使用方式及原理，PXIe系列数据采集卡冷端补偿原理。着重对不同接线方式产生的测量结果进行了理论分析，并通过实验验证了理论分析结果。进而提出如何对安装完成的热电偶进行系统全面的接线检查。%The principle of thermocouples used and thermal-hydraulic experiment, cold junction compensation principle PXIe serial data acquisition card. Focuses on the different ways of measuring results of theoretical analysis and experimental verification of results of the analysis. Presented how to check the comprehensive wiring system of thermocouple installation is complete.
