method and device for contactless determination of the electrical conductivity of an electrically conductive substance

摘要

method and device for contactless determination of the electrical conductivity of an electrically conductive substance.they are suitable for single - and dauermessungen to aggressive and hot substances.the substance is by a transversal magnetic field, eddy currents generated in the substance which is electrical.the interaction between the magnetic field produces a force systems have and the magnet is evident.the specific electrical conductivity is the measurement of the force and the simultaneous measurement of the cumulative mass of the substance.using the cumulative volume of the electric conductivity.
