Abstract

At least two magnetoresistors laid out perpendicularly are used. These magnetoresistors are installed in a bridge, the measurement signal being taken from the mid-point of the bridge. This signal is linear over a very wide range. Application to measurement of the orientation of a magnetic field or the angular position of an object.
