Measurement process

The calculation routine of the m-axis-system is based on the determination of the dipole parameters of permanently magnetic materials using an integrated AMR sensor set-up. That way the three-dimensional position (x, y, z) of the magnet as well as its magnetic moment (m) and the angular direction (ϕ, θ) of the magnetization are determined simultaneously.

Because of the universally applicable approach the evaluation of axially as well as diametrically magnetized dipole permanent magnets regarding their quality and strength. By implementation of various user defined magnet types and measurement processes in the comprehensive user software the system delivers a real time classification of numerous dipole possibilities. All relevant settings and measurement results can be saved to a single report file.
