Title:
MAGNETORESISTIVE LINEAR POSITION SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/196835
Kind Code:
A1
Abstract:
A magnetoresistive linear position sensor, comprising a permanent magnet (1) and a magnetoresistive sensor chip (2); one of the permanent magnet (1) and the magnetoresistive sensor chip (2) is fixed; the permanent magnet (1) and the magnetoresistive sensor chip (2) are in relative motion along a fixed motion path; the sensitive direction of the magnetoresistive sensor chip (2) is a direction perpendicular to the fixed motion path; the magnetoresistive sensor chip (2) senses the change in the magnetic field caused by the change in the relative positions of the magnetoresistive sensor chip (2) and the permanent magnet (1), outputs a voltage signal changing with the position, and converts same into position information by means of signal processing.
