Abstract
A magnetic torque sensing device having a disk-shaped member with a magnetoelastically active region. The magnetoelastically active region has a magnetically conditioned region with an initial direction of magnetization that is perpendicular to the sensitive directions of magnetic field sensor pairs placed proximate to the magnetically active region. Magnetic field sensors are specially positioned in relation to the disk-shaped member to accurately measure torque while providing improved RSU performance and reducing the detrimental effects of compassing.
