利用虚拟仪器技术实现变温电阻阻值与温度同步传输

Transfer Thermistor's Resistance and Temperature In-phase by Visual Instrument

为解决热惯性滞后效应引起的变温电阻阻值与温度无法同步传输的问题,利用虚拟仪器软件Lab-VIEW开发了变温电阻测量系统,并结合电阻分压法,实现了阻值与温度的同步传输,有效提高了测量精度.此方法新颖、独特,是虚拟仪器技术在大学物理实验中得到应用的一个成功实例.

In order to solve the influence of heat-inertia that results in the thermistor＇s resistance and temperature doesn＇t transfer in-phase, a measurement system was designed by LabVIEW. By this system and a voltage-divided circuit, we can transfer thermistor＇s resistance and temperature in-phase and improve the accuracy of measurement. It＇s a new idea of measurement and it is a typical example of applying virtual technology into physics experiment.
