基于 LabVIEW 的热敏电阻自动测试系统是由热敏电阻和555定时器构成的多谐振荡电路,其关键是将热敏电阻阻值变化转换为频率变化,结合 LabVIEW采集电路实现电阻对频率的测量,使其自动完成电阻值测量。该系统在仿真、软件控制、跨平台操作等方面有广泛的应用。
Thermistor automatic testing system based on LabVIEW is a multivibrator circuit composed of a thermistor and the timer 555. It can make the thermistor resistance to frequency. With LabVIEW acquisition circuit, it can automatically convert the measured value into a resistance value and display a fully automatic test system. The system could be used in the field of the simulation, the software controlling and the cross-platform operation.
