More Information
Summary: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.
