Abstract

In this paper we present results on the response of linear variable differential transformers (LVDT) using FeSiB glass covered wires as active cores. First we demonstrate that the noise level of the sensor decreases with the magnetostriction coefficient of the magnetic core of the wire. Magnetic noise is further decreased after heat treatment, magnetic annealing and stress-current annealing. These results are in relatively acceptable agreement with results presented in the past by other research groups.
