Abstract: A system and method for magnetizing a ferromagnetic element is disclosed. Electrodes are positioned on opposite surfaces of the ferromagnetic element and a current is applied to the electrodes, resulting in the formation of a magnetically conditioned region on the ferromagnetic element. Magnetic field sensors may be placed proximate the magnetically conditioned region. Output signals from the magnetic field sensors may be indicative of a load or torque applied to the ferromagnetic element.

Abstract: A magnetoelastic sensor. The magnetoelastic sensor uses strain-induced magnetic anisotropy to measure the tension or compression present in a plate. During construction, an annular region of the plate is magnetized with a circumferential magnetization. Magnetic field sensors are placed near this magnetized band at locations where the magnetization direction is non-parallel and non-perpendicular to the axis of tension. The strain-induced magnetic anisotropy caused by tension or compression then produces a shift in the magnetization direction in the plate regions near the field sensors, thereby causing magnetic field changes which are detected by the magnetic field sensors. The magnetic field sensors are connected to an electronic circuit which outputs a voltage signal which indicates the tension or compression in the plate.

Abstract: A system and method for creating one or more magnetically conditioned regions on a rotatable shaft or disk-shaped torque sensing element, wherein rotation noise produced by the element due to magnetic field variations is substantially negated. Upon magnetization of the torque sensing element, rotation noise produced by the magnetically conditioned region is measured. Adjustment factors are calculated based on the measured rotation noise, and the adjustment factors are used to adjust a magnetic field source during subsequent magnetization of the torque sensing element.
