Simulation Analysis of Output Characteristic of the Inductive Displacement Transducer

Abstract:

Aiming at the structure and electromagnetic induction characteristics of inductive displacement transducers, it is inevitable to appear the problem between nonlinearity output and temperature drift, by which it’s testing accuracy is affected, on the basis of analysis of structural characteristics and working principle of the inductive displacement sensor, mathematical model of the relationship between input and output has been constructed, which can be simulated and analyzed by MATLAB software. The results indicate that the inductive displacement transducer has an proximately linear extent ( ) and the linearity errors are influenced by the coils number and the semidiameter;In the case of relatively constant of other parameters, when the coil of radius and the number of coil turns are fixed ,there will be the core displacement x and , the sensor output characteristic has an favorable linearity under the circumstances of changing the coil radius and the number of turns in proper sequence; When ,the output property of the sensor appears worse linearity.
