Abstract
Pour protéger le fonctionnement d'un thermocouple (2) contre le rayonnement d'un élément (20, 44) radiatif d'un environnement dans lequel il est placé, la présente invention a pour but de proposer un système de protection du thermocouple (14) comportant une plaque (18) disposée entre le thermocouple (14) et l'élément (20, 20', 44) radiatif, la plaque présentant un état de surface global de sa face (22) interne orientée vers le thermocouple (14) tel que la face (22) absorbe plus qu'elle ne réfléchit le rayonnement provenant de l'élément (20, 20', 44).
