【摘要】 使用 Keithley公司生产的 A/ D转换卡 (DAS- 80 1)及自带的开发应用程序接口 Driver L INX,开发出一个适用于不同温度及不同电压测量范围的电阻 -温度 (R- T)关系的计算机自动测量系统。该系统可以实现对 A/ D卡进行实时控制 ,自动采集数据和处理数据 ,并可以根据不同的测量对象对测量结果进行实时显示。系统具有较好的稳定性、较高的准确度和精度 ,适用于从几 μV到 10 V以内不同范围的电信号的测量更多还原

【Abstract】 A Keithley DAS 801 A/D board and the DriverLINX,a industry standard,high performance,real time data acquisition engine were successfully used to construct a data acquisition system for a Resistance Temperature measurement,which can automatically acquire,process and save real time data,and draw graphs. The stability and veracity of the system are good enough for measuring the voltage signal from several μV to 10V.更多还原
