摘要

Method for the galvanically separate, non-contacted measurement of the absolute value of impedances, essentially characterized by comprising an oscillating step containing a feedback transformer, a demodulator step and a current source, with the feedback transformer carrying a third winding that is closed by the impedance to be measured and is so shaped and moves, in relation to the other two windings of the feedback transformer only in such a way, that the concatenations of magnetic fluxes in the feedback transformer do not suffer variation.
