利用Hall效应制成的Hall电流传感器,其主体由两部分组成,其一为Hall片,其二为束磁芯,为高μi合金切口磁芯。切口磁芯的导磁率μr=1(1/μi+1g/1c),式中,μr为切口磁芯导磁率,μi为封闭环导磁率,Ic为磁路长度(cm),Ig为气隙长度(cm)。当μi>>1时则有μr≈Ic/Ig,开气隙磁芯的剩磁Br∝Ic/Ig·Hc,即Br∝μr·Hc。为准确无误
Hall effect sensor made of Hall effect, the main body consists of two parts, one for the Hall piece, and the second for the beam core, a high-μi alloy notch core. The permeability of the cut core μr = 1 (1 / μi + 1g / 1c), where μr is the permeability of the cut core, μi is the closed loop permeability, Ic is the length of the magnetic circuit (cm), Ig is the air gap Length (cm). When μi >> 1 then there μr ≈ Ic / Ig, open air gap magnetic core BrαIc / Ig · Hc, that is Brαμr · Hc. To be accurate
