Abstract

The grating eddy current displacement sensor (GECDS) for displacement or position measurement used in watertight electronic digital caliper was described. The parameters optimization of the sensor is essential for economic and efficient production. The purpose of this study is to determine the optimal combination of the sensor parameters and analyze the effects of these parameters on the nonlinearity of the sensor. The effects of the sensor parameters on nonlinearity are studied by finite element method (FEM). Multi parameter optimization is realized through orthogonal experimental design (OED) method combined with FEM.
