MAGNETORESISTIVE SENSOR FOR MEASURING THE MAGNITUDE (ABSOLUTE VALUE) OF MAGNETIC FIELD

摘要

The magnetoresistive sensor is designed for positioning of moving magnetic parts. The sensor according to the utility model comprises a basic sensitive element embodied in the form of a thin- or thick-film structure of magnetoresistive material with anisotropic magnetoresistive effect. The basic sensitive element is in the form of an arched bus with an arc angle of 180 degrees, with a length / width ratio greater than 10, and an anisotropy axis following the curvature of the arc. In an embodiment, a magnetoresistive sensor is described whose basic element of 180 degrees is divided into two complementary segments: an arch with an arc angle of 90 degrees and an arch with an arc angle of 90 degrees, which are turned at 90 degrees to one another.
