Design of Intelligent Measurement System for Dynamic Magnetic Properties in a Single Sheet Sample
Single sheet sample is manufactured according to related national standards for measuring material dynamic magnetic properties conveniently and rapidly. A intelligent measurement system is built in LabWindows/CVI platform based on the technology of virtual instrument after theoretical analysis of magnetic field strength and magnetic flux density. And the acquisition and processing equipments are selected via experimental debugging. In addition, the software interface is set between LabWindows/CVI and Matlab for updating the system and increasing functions later such as harmonic analysis. Finally, the analysis of acquired signals,measurement results and K-value calibration demonstrates availability and stability of the system that provides theoretical guidance and practical experience for measuring other sheet samples and static magnetic properties.
