Abstract
L'INVENTION CONCERNE UN DISPOSITIF POUR PRODUIRE UN SIGNAL NUMERIQUE A LA SORTIE D'UN TRANSDUCTEUR DE DEPLACEMENT. SELON L'INVENTION, IL COMPREND UN CONVERTISSEUR 32 POUR CONVERTIR UN SIGNAL ANALOGIQUE D'UN CYCLE D'OPERATION DU TRANSDUCTEUR COMPRENANT UNE POSITION INITIALE ET UNE POSITION DE MESURE EN UN SIGNAL NUMERIQUE, UN MOYEN 38, 40 POUR ENREGISTRER LES VALEURS DUSIGNAL NUMERIQUE REPRESENTANT LA POSITION INITIALE ET LA POSITION DE MESURE, ET UN MOYEN 42, 50, 54 POUR DERIVER LE SIGNAL NUMERIQUE SELON LA DIFFERENCE ENTRE LES VALEURS ENREGISTREES. L'INVENTION S'APPLIQUE NOTAMMENT AUX ENREGISTREURS DE DEPLACEMENT POUR MESURER LES DEFORMATIONS DES ROUTES.
