Abstract

L'invention concerne un dispositif pour le diagnostic d'état et la commande d'un composant (12) hydraulique, en particulier d'un cylindre hydraulique (13), qui est relié à une source de fluide (10) par l'intermédiaire d'un canal de fluide (11). Un module de diagnostic (23) électronique sert à diagnostiquer l'état du composant hydraulique (12), au moins grâce la détection de l'écoulement du fluide, réalisée au moyen d'un dispositif de mesure (29) de l'écoulement. Ledit module de diagnostic (23) comprend au moins une conduite directe (22) fluidique, qui permet le diagnostic à l'aide du dispositif de mesure (29) de l'écoulement, et qui forme, avec au moins une conduite de fluide (21, 24) disposée à la suite, le canal de fluide (11). Au moins une des conduites de fluide (21, 24) est dotée d'au moins deux conduites intégrées, électriques ou optiques destinées à transmettre les données et/ou l'énergie. Le module de diagnostic (23) est en relation électrique ou optique avec une centrale (23) de commande et/ou de surveillance recevant les données de diagnostic. On peut produire les relations fluidiques et électriques ou optiques simultanément grâce à un enfichage simple de la source de fluide (10) dans le module de diagnostic (23) et dans le composant hydraulique (12), au moyen des conduites de fluide (21, 24), ce qui permet de simplifier le montage et de diminuer les frais de pose de câbles.
