Title
(EN) CALIBRATION OF WEAR DETECTION SYSTEM
(FR) ÉTALONNAGE POUR SYSTÈME DE DÉTECTION D'USURE
Abstract
(EN)
A method of wear detection of a coated belt or rope includes measuring an initial electrical resistance of one or more cords, strands or wires of the coated belt or rope. The initial electrical resistance is calibrated by repeating the measuring of initial electrical resistance and populating a database with the measured initial electrical resistance values. A true initial resistance is determined from the population of initial electrical resistances and subsequent measured values of electrical resistance of the one or more cords, strands or wires of the coated belt or rope.
(FR)
La présente invention porte sur un procédé de détection d'usure d'une courroie ou d'une corde revêtue, qui comprend la mesure d'une résistance électrique initiale d'une ou plusieurs cordes, d'un ou plusieurs brins ou fils de la courroie ou corde revêtue. La résistance électrique initiale est étalonnée par répétition de la mesure de résistance électrique initiale et remplissage d'une base de données avec les valeurs de résistance électrique initiale mesurées. Une résistance initiale vraie est déterminée à partir de la population de résistances électriques initiales et de valeurs mesurées subséquentes de résistance électrique d'une ou plusieurs cordes, d'un ou plusieurs brins ou fils de la courroie ou corde revêtue.
