Ml. Kruchinin, EFFECTS OF ENGINEERING TOLERANCES ON THE ERROR OF A PLANAR CAPACITANCE DISPLACEMENT SENSOR, Measurement techniques, 38(4), 1995, pp. 407-410
The paper discusses the effects of manufacturing tolerances on the lin
earity errors of a planar capacitative displacement sensor. A numerica
l evaluation is given together with working formulas for the effects o
f gap taper in the working electrodes, the curvature of the inner edge
s of these electrons, and taper in the outer edges.
