Abstract
(EN) A system for monitoring the stresses in a pipeline for conducting fluid materials, comprising sets of stress-sensing elements (Q1, ...., Qn) electrically connected together at spaced locations along the pipeline, groups of the sets being electrically connected together to form zones (1, ....., N), the respective zones being electrically connected to accumulation centers (3) where data from the sets of sensors is accumulated and reduced, and a central control (7) electrically connected to the accumulation centers (3) for receiving, interpreting and displaying information from the sensing elements.
(FR) Un système de contrôle des contraintes d'un pipeline de transport de matériaux fluides comprend des ensembles d'éléments de détection de contrainte (Q1,...Qn), lesquels sont électriquement connectés ensemble en des points espacés le long du pipeline, des groupes de ces ensembles étant électriquement connectés ensemble pour former des zones (1,...,N), les zones respectives étant connectées électriquement à des centres d'accumulation (3) où les données provenant des ensembles de détecteurs sont accumulées et réduites, et une commande centrale (7) électriquement connectée aux centres d'accumulation (3) pour recevoir, interpréter et afficher les informations provenant des éléments de détection.
