Abstract

Selon un mode de réalisation de la présente divulgation, il est décrit un thermocouple qui comprend une composante électrique, comme une résistance, au niveau ou à proximité immédiate dune jonction où la température devrait être mesurée. En surveillant les mesures de tension analogique, le système détermine, par exemple, si la température mesurée représente actuellement une lecture de température au niveau de la jonction ou si le thermocouple a été compromis en raison dun ou de plusieurs problèmes de santé, comme un court-circuit dans le thermocouple, ce qui cause une fausse jonction.
