Abstract

In this paper the magnetic field distribution of solenoid is analyzed when the core moves along with the displacement of the object and an important substantial nonlinear error source is found. Based on the analysis, a new structural LVDT is designed which generates an even segment in its magnetic field distribution. This even segment doesn't change when the core moves along with the displacement of the object and thus the nonlinear error can be theoretically avoided. The basic experiments have proved that the nonlinear error of this new structure transformer is much smaller than the traditional one with same dimensions. In the second part of this paper, characteristic models of this new structure LVDT have been given which are the basis of further designing its parameters.
