Anisotropic magnetoresistive sensor – the detector of constant magnetic field

Bondarenko Valeriy Gavrilovich, Markina Irina Sergeevna

This article describes the detector of constant magnetic field on the basis of anisotropic magnetoresistive (AMR) sensor. Features of design and characteristics of the chosen detector are resulted. The block diagram apparatus for measuring the main parameters of detector is presented. The measurements of the output voltage for 16 AMR sensors are resulted.
