The invention relates to a device for conveying a substance that comprises: a first duct (1) for containing the substance; an optical fibre (5) connected to the first duct (1) and extending along said duct, the optical fibre including several detection members (71, 75) spaced along its length, each detection member having a separate reflection spectrum that varies with the presence of the substance to be detected; a control device including a light source capable of emitting a light in the reflection spectrum of each detection member, a light receiver capable of detecting the light amplitude in the detection spectrum of each detection member, and an analysis module capable of determining the presence of a leak of the substance based on the light amplitude provided by the light receiver.

L'invention concerne un dispositif de transport d'une substance, comprenant : une première conduite (1) destinée à contenir la substance; une fibre optique (5) solidaire de la première conduite (5) et s'étendant le long de cette conduite, la fibre optique (5) présentant plusieurs organes de détection (71, 75) espacés sur sa longueur, chaque organe de détection présentant un spectre de réflexion distinct, variant en fonction de la présence de la substance à détecter; un dispositif de contrôle présentant une source lumineuse apte à émettre une lumière dans le spectre de réflexion de chaque organe de détection, un récepteur lumineux apte à détecter l'amplitude d'une lumière dans le spectre de réflexion de chaque organe de détection, et un module d'analyse apte à déterminer la présence d'une fuite de la substance en fonction de l'amplitude lumineuse fournie par le récepteur lumineux.
