Conception and Realisation of a Sensor Electromagnetic Force-Displacement

Abstract

The experimental device that we propose is an electromagnetic sensor permits the measures of force and displacement. her principle of working rests on the phenomenon of influence by magnetic induction between two flat spools, in the same way diameter and including the same number of spires, situated to a certain distance, x, one of the other, on a same axis passing by their centers. The sensor is constituted of two converters, the first is the spring (converter force-displacement), and the second is a magnetic circuit permitting the conversion of the displacement in tension (converter displacement-tension) via the electronic circuit of conditioning.
