Functional principle
The voltage induced in the measurement coils (field probe) is evaluated in
order to measure the magnetic flux density. The signal voltages are digitized
and evaluated by a digital signal processor (DSP). The DSP calculates the
measurement result from the voltages. The orthogonal configuration of the
three measurement coils allows the field to be measured isotropically (i.e.
independent of spatial direction).
