摘要

基于 NI USB-6210 数据采集卡，采用 LabVIEW 设计了铂电阻温度系数测量系统。该系统可定量、实时记录并直观显示非平衡电桥输出电压随温度的变化过程，在同一坐标界面中显示不同参量的多条实验曲线，并实现曲线斜率拟合计算等数据处理功能。实验结果表明，系统操作方便，测量精度高，能够更好的满足科研测试和教学实验的要求。

Abstract:

An experimental system for the measurement of the temperature coefficient of Platinum resistance was designed base on NI USB-6210 data acquisition card and LabVIEW．The system could record and display the change of temperature vs output voltage of unbalanced bridge in real-time． Multi experimental curves of different parameters could be displayed simultaneously，which could help us to slope of the calibration curve．The experimental results show that the proposed system makes the process of measurement intuitive and accurate，and it can better meet the requirements of scientific research test and teaching experiment．

Key words: platinum resistor coefficient of resistance temperature unbalanced bridge data acquisition card LabVIEW
