Abstract
The derived formula of ring-plate capacitor in homogeneous medium is introduced
the measurement thickness range is analyzed
and the theoretical curve is drawm.Also
the thickness of nonmetal medium is tested using the capacitance sensor.The experimental curve are drawn.The theoretical curve with the experimental one is compared
and that nonmetal medium tested by this method is practical.The measurement range for this method is 0
