【Abstract】 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.更多还原
