MAGNETIC FIELD MONITORING OF AREAS

1. 12-CHANNEL MAGNETIC FIELDS ANALYZER Suitable space arrangement of independent magnetic sensors allows contactless detection of moving objects containing hard or soft ferromagnetic as well as processes accompanied by changes of magnetic fields generated by electric currents. For the entire analysis of magnetic processes in the certain area it is necessary to know vectors of magnetic induction in four points (3 points within a plane and 1 outside of it) and basic x-y-z combinations of gradients. This can be obtained with appropriate arrangement of 12 independent sensors working in synchronous mode.
