摘要
结合实验室虚拟仪器集成环境(LabVIEW)开发简单的虚拟传感器应用界面,实验制作电涡流传感器。依据工作原理及制作工艺设计了合理的电涡流传感器的结构及信号调理电路,制作出探头直径为10 mm、测量范围2～3 mm、分辨率0.1 mm的电涡流传感器,并利用多参数曲线拟合方法进行测试标定。实际实验过程及结果表明,研制的传感器性能稳定可靠。
To manufacture eddy current sensor in experiment,LabVIEW was used to build simple virtual interface for sensors.Based on the virtual instrument interface with Labview,spiral coils of sensor with 10 mm diameter,2-3 mm measuring range and 0.1 mm resolution were manufactured in experiment.And multi-parameter curve fit was used to calibrate the sensors.The experimental process and results show that the sensors made in experiment are of stability and reliability.It is helpful for students to understand the theory and application of eddy current sensor easily.
