High-Accuracy Conductivity Measurements in Nonferrous Metals

Source

An eddy-current instrument has been built that measures electrical conductivity with a high degree of accuracy and precision. The instrument measures the electrical conductivity of nonferrous metals at a constant skin depth. By keeping the product ωσ constant in all measurements, a linear relationship between conductivity and frequency can be established. Due to this linear relationship, only one conductivity standard is necessary to calibrate the instrument over the full range of 1 to 100 percent international annealed copper standard (IACS).
