Test and analysis of fluxgate sensor probe

In this paper,the performance parameters of fluxgate sensor are analyzed,and the method to improve the performance of magnetic probe is proposed.In fact,cobalt based amorphous alloy is selected as the core material,and the probe is made by using the approximate formula.The experimental results show that the optimized magnetic probe has lower noise,higher sensitivity and better temperature performance,and the performance of fluxgate sensor meets the design requirements.
