Abstract

In this paper we present results on load sensors based on the magnetostrictive delay technique. The sensors translate the displacement of soft magnetic plate, hard magnetic disk and aluminium disk into force with respect to three different magnetostrictive delay line set-ups. The range of displacement determines the range of measurable load. Stainless steel springs have been used as active core supports. The best results both in sensitivity and repeatability have been obtained using soft magnetic plate as active core.
