Title
(EN) SENSOR CONSTRUCTION AND METHOD FOR MANUFACTURING AN ARTICLE WITH AN EMBEDDED SENSOR
(FR) CONSTRUCTION DE CAPTEUR ET PROCÉDÉ DE FABRICATION D'UN ARTICLE AYANT UN CAPTEUR INTÉGRÉ
Abstract
(EN)
Sensor construction (1), which construction comprises a sensor (2), wherein the sensor construction (1) comprises a heat insulating material cover (3) for embedding the sensor construction inside metal material of a component (10), inside which heat insulating material cover the sensor is located, and which heat insulating material cover comprises a level surface section for correct positioning of the sensor construction inside the component during powder bed fusion additive manufacturing process of the component, and a hole (4) extending as a substantially straight channel from the outer surface of the heat insulating material cover to the sensor inside the heat insulating material cover. The invention also relates to a method for manufacturing an article with such a sensor construction (1) embedded.
(FR)
L'invention concerne une construction de capteur (1), laquelle construction comprend un capteur (2), la construction de capteur (1) comprenant un couvercle de matériau d'isolation thermique (3) pour incorporer la construction de capteur à l'intérieur d'un matériau métallique d'un composant (10), le capteur étant situé à l'intérieur dudit couvercle de matériau d'isolation thermique et lequel couvercle de matériau d'isolation thermique comprenant une section de surface de niveau pour un positionnement correct de la construction de capteur à l'intérieur du composant pendant le processus de fabrication additive par fusion de lit de poudre du composant, et un trou (4) s'étendant sous la forme d'un canal sensiblement droit depuis la surface externe du couvercle de matériau d'isolation thermique vers le capteur à l'intérieur du couvercle de matériau d'isolation thermique. L'invention porte aussi sur un procédé pour fabriquer un article ayant une telle construction de capteur (1) intégrée.
