Title
(EN) ROTATION ANGLE POTENTIOMETER
(FR) POTENTIOMETRE DE MESURE DE L'ANGLE DE ROTATION
Abstract
(EN) A potentiometer for the redundant measurement of the rotation angle of a shaft (2) with respect to a stationary part has two concentric arc-shaped resistance tracks (4, 5) on a stationary disc (1). Two concentric circular collector tracks (14, 15) are arranged on a disc (3) which is parallel to the stationary disc and rotates with the shaft (2). Two collector brush grinders (17, 18) are in contact with the two resistance tracks (4, 5). Two redundant measurements are made at two terminal lugs (10, 11) attached to the stationary disc (1), which are connected to the collector tracks (14, 15) through two collector brush grinders (12, 13).
(FR) Un potentiomètre de mesure redondante de l'angle de rotation d'un arbre (2) par rapport à une partie statique comprend deux bandes concentriques de résistance (4, 5) en arc de cercle agencées sur un disque statique (1). Deux bandes collectrices (14, 15) concentriques circulaires sont agencées sur un disque (3) parallèle au disque statique et qui tourne avec l'arbre (2). Deux balais conducteurs (17, 18) connectés aux bandes collectrices (14, 15) sont en contact avec les deux bandes de résistance (4, 5). Deux valeurs redondantes de mesure sont saisies par deux barrettes (10, 11) fixées sur le disque statique (1) et en contact avec les bandes collectrices (14, 15) par l'intermédiaire de deux balais conducteurs (12, 13).
