What is your main concern/task to be solved?

The SENIS Magnetic Field Mapper measures the magnetic field around permanent magnets and electromagnets. By means of a 3-axis Hall Probe, it generates a 3D map of the magnetic field, measures the dipole moment, counts number of poles, calculates pole width and pole distribution for multipole magnets and rotors, measures magnetic angle, angle error, field homogeneity, etc. The integrated touch sensor accurately combines coordinate measurement with very accurate magnetic field mapping. Our innovative smart connection technology allows an easy interchange of Hall and AMR probes, touch stylus and other specialized probes, such as eddy-current probes for crack detection, sliding probes for in-contact measurements, probe arrays, etc.
