Abstract

EN UN PROCEDIMIENTO Y UNA DISPOSICION DE CONEXION PARA EL CONTROL DE LAS RESISTENCIAS DE PASO EN UN POTENCIOMETRO QUE PERTENECE A UN DISPOSITIVO CONTROLADOR Y/O REGULADOR DE UN VEHICULO Y QUE SE UTILIZA COMO TRANSMISOR DE MANDO. EL POTENCIOMETRO SE IMPULSA CON UNA TENSION CONSTANTE; LA TENSION AL RECTIFICADOR DEL POTENCIOMETRO SE SUMINISTRA POR UN DISPOSITIVO ANALIZADOR. LA TENSION EN EL RECTIFICADOR SE CARGA CON UNA RESISTENCIA Y SE ANALIZA LA DIFERENCIA ENTRE LA TENSION CARGADA Y NO CARGADA.
