Abstract

L'invention porte sur un ensemble capteur de température à fibre optique qui comporte un capuchon avec une cavité interne. Un élément capteur est reçu dans la cavité interne du capuchon. L'élément capteur présente des propriétés de transmission de lumière conçues pour changer avec des variations de température. Une fibre optique possède une première extrémité reçue dans la cavité interne du capuchon, et une seconde extrémité de la fibre optique conçue pour être reliée à une unité de traitement pour transmettre des signaux lumineux entre l'élément capteur et l'unité de traitement. Un dispositif de pression est reçu dans le capuchon et appuie contre l'élément capteur de telle sorte que ce dernier est en contact fonctionnel avec la première extrémité de la fibre optique pour une transmission de lumière entre eux durant le fonctionnement de l'ensemble capteur de température à fibre optique.
