CONTINUOUS TEST DEVICE FOR DETERMINING THE MAGNETIC PROPERTIES OF A STRIP OF A MOVING MATERIAL, INCLUDING A METHOD FOR OBTAINING AN AVERAGE, THE NOW LOW, NOW, NOW, NOW, NOW, NOW, AND NOW, OVERALLLY AND NOWALLLY
Continuous testing apparatus for determining the magnetic characteristics of a strip of moving material including a flux inducing and pick-up device to induce a quantity of flux into the material and dual voltage output producing coils for producing different voltages from material having the same magnetic permeability, and circuit means coupled with the dual coils to produce an output voltage which is a characteristic of the ratio of the voltage produced by one of the coils and the difference between the voltages produced by both of the coils. The invention also includes the method of obtaining a profile of the coil of the material throughout the entire length thereof.
