Abstract

L'INVENTION CONCERNE LES JAUGES D'EPAISSEUR. ELLE SE RAPPORTE A UNE JAUGE D'EPAISSEUR COMPRENANT UN TRANSDUCTEUR AYANT UN ELEMENT EMETTEUR 22 ET UN ELEMENT EMETTEUR ET RECEPTEUR 26. LES BLOCS 24 ET 28 DE MATIERE QUI PORTENT LES ELEMENTS TRANSDUCTEURS N'ONT PAS LA MEME LONGUEUR, LA DIFFERENCE DE LONGUEURS CORRESPONDANT A UNE DIFFERENCE DE TEMPS DE PARCOURS QUI EST EGALE AU RETARD GEOMETRIQUE INTRODUIT LORSQUE LE TRANSDUCTEUR EST UTILISE AVEC LES DEUX ELEMENTS 22 ET 26. LA JAUGE PEUT ALORS ETRE ETALONNEE SANS AUCUN BLOC D'EPREUVE. APPLICATION A LA SURVEILLANCE DE LA CORROSION PAR MESURE ULTRASONORE D'EPAISSEUR DE PAROIS.
