Abstract

L’invention concerne un dispositif (1) de mesure et de surveillance de la température d’un objet, le dispositif (1) comprenant : un capteur de température (2) à bilame (3, 8) comprenant une partie mobile (3b, 8b) configuré pour se déplacer lors d’un changement de température, un moyen d’affichage permanent (5a, 9, 26, 27) d’au moins une valeur prédéfinie de température lorsque l’objet a atteint l’au moins une valeur prédéfinie, dans lequel la partie mobile (3b, 8b) est configurée pour initier l’affichage par le moyen d’affichage permanent (5a), l’affichage étant irréversible. Figure pour abrégé : [Fig. 1 ]The invention relates to a device (1) for measuring and monitoring the temperature of an object, the device (1) comprising: a temperature sensor (2) with a bimetallic strip (3, 8) comprising a movable part (3b, 8b) configured to move during a temperature change, a permanent display means (5a, 9, 26, 27) of at least one predefined temperature value when the object has reached the at least one value predefined, in which the mobile part (3b, 8b) is configured to initiate the display by the permanent display means (5a), the display being irreversible.
