Automatic instrumental platform for the measurement of the characteristics of ferromagnetic materials based on LabVIEW

Authors: MONIA FERJANI JAAFAR

Abstract: In this paper, we propose a complete automation of the different measurements of ferromagnetic materials dynamic characterization according to the CEI60404-6 standard. The measurement bench consists of two major parts: hardware and software. The hardware part comprises a programmable function generator MTX-3240, an electronic card for the magnetic induction's waveform control, and an NI PCI-6225 acquisition card. The software part is developed in the LabVIEW environment to enable the generator and the acquisition card control. It also allows for the processing of obtained experimental records and the correction of static errors. The identified characteristics are mainly the first magnetization curve, the static and the differential permeability, the hysteresis loop characteristics, and the core loss measurements.
