摘要
本文利用霍尔器件线性度的特点,构成高精度磁通计,通过测量流过电流的导体周围的磁场的磁通密度,从而测定电流。是一种非接触测量,既安全又简便。
In this paper, we introduce the constructure of high precise magnetic flux meter based on the principle of linearity feature of Hall device. By measuring the magnetic flux density of the megnetic field surrounding the wire with the Hall device, we can achieve the electric current through the wire. As it is noncontact measurent, the method is easy and safe.
