The demands on the accuracy of magnetic measuring systems, consisting of magnetic sensors and permanent magnets as measuring scales, are constantly increasing. Rotary encoders or motor feedback systems must achieve ever greater precision in order to either position more accurately or achieve better efficiency and lower torque ripple. These requirements place new demands not only on the sensor technology, but also on the magnets used and therefore on the measurement technology used for incoming and outgoing goods inspections along the value chain. With cylindrical or cuboid dipole magnets, which are very often used for on- and off-axis angle measurement or for switching operations, material inhomogeneities or manufacturing defects can lead to asymmetrical magnetization or inhomogeneous magnetic field characteristics. With the ELSOMA C10 flux density measuring device, such errors are detected much faster than with previous solutions, such as Helmholtz coils.
