Abstract
(EN)
A leak detection system comprising: an adapter configured to be coupled to a conduit and direct leakage from the conduit to a leakage sensor, wherein the adapter comprises a wick comprising: a hydrophilic material, a cationic polymer material, an anionic polymer material, a hydrophilic non-ionic material, or any combination thereof. A leak detection system comprising: a laminate adapted to transport leaked fluid from a conduit to a leakage sensor, wherein the laminate comprises: a wick adapted to transport the leaked fluid; and an adhesive adapted to secure the wick to the conduit. A leak detection system comprising: a wick disposed on a substrate and adapted to transport leaked fluid from a conduit to a leakage sensor, wherein the wick comprises a plurality of fluid channels in a matrix arrangement.

La présente invention concerne un système de détection de fuite comprenant : un adaptateur conçu pour être accouplé à un conduit et diriger une fuite du conduit à un capteur de fuite, l'adaptateur comportant une mèche comprenant : un matériau hydrophile, un matériau polymère cationique, un matériau polymère anionique, un matériau hydrophile non ionique ou toute combinaison de ceux-ci. L'invention concerne un système de détection de fuite comprenant : un stratifié conçu pour transporter un fluide qui a fui d'un conduit à un capteur de fuite, le stratifié comprenant : une mèche conçue pour transporter le fluide qui a fui ; et un adhésif conçu pour fixer la mèche au conduit. L'invention concerne un système de détection de fuite comprenant : une mèche disposée sur un substrat et conçue pour transporter un fluide qui a fui d'un conduit à un capteur de fuite, la mèche comprenant une pluralité de canaux de fluide dans un agencement matriciel.
