  • Abstract
    THE instrumentation described in this paper is based upon the variation of mutual inductance between two coils when brought near a metal surface. A type of thickness gauge employing this principle was first publicized by M. L. Greenough1¿4; he stated that the signal obtained from a mutual inductance was ¿greater and more linear¿ than from self-inductance. Since then applications of the principle have been extended to the measurement of distance and vibration.
