Paper Abstract

This paper gives an outline of the self-calibrated capacitive instrument for measuring the thickness of coating on metal. Based on the improved method about reducing the influence of fringing effect, stray capacity etc., a 3-parameters model is proposed, by which the nonlinear calibration is very convenient in measuring different materials,
