Abstract

This paper presents a prototype of Linear Variable Differential Transformer, which has been designed, simulated and produced in order to observe, study and characterize the effects on its working of an external interfering magnetic field. The LVDT prototype has been first simulated, both in standard conditions and in case of external interference, by using the FEM software FLUX. The design guidelines coming from the simulations have been used to develop the prototype and a complete set of measurements has been performed on it. A comparison between simulations and measurements is then proposed.
