摘要
Abstract
A measurement system of magnetic azimuth is developed based on biaxial MI effect. Magneto-impedance effect driven by sharp pulse current is analyzed. A sensitive,stable and low power consumption magnetic sensor is constructed using a CMOS multivibrator circuit,in which a sharp pulse current is applied to the amorphous wire. It can realize calculation of magnetic azimuth and digital output through LabVIEW software. Experiments show that the system has good interface,easy operation,high precision and can store,analyze measurement data easily.关键词
