Qu'est-ce qu'un capteur de temp\u00e9rature ?<\/b><\/h2>\r\n<span style=\"font-weight: 400\">Un capteur de temp\u00e9rature est un dispositif qui mesure la temp\u00e9rature d'un objet.<\/span>\r\n\r\n<span style=\"font-weight: 400\">Le capteur de temp\u00e9rature lui-m\u00eame n'a pas la capacit\u00e9 d'indiquer la valeur de la temp\u00e9rature. Si vous souhaitez indiquer cette valeur, vous pouvez utiliser notre <span style=\"color: #ff0000\"><a style=\"color: #ff0000\" href=\"https:\/\/lorentzzi.com\/fr\/categorie-produit\/temperature-controller\/pid-temperature-controller\/\">indicateurs de temp\u00e9rature ou r\u00e9gulateurs de temp\u00e9rature<\/a><\/span>qui peut convertir le signal \u00e9lectrique du capteur de temp\u00e9rature en une valeur num\u00e9rique visible et mesurable et l'afficher sur l'\u00e9cran de l'indicateur.<\/span>\r\n<h2 style=\"font-size: 20px\"><b>2.

Il existe deux principaux types de thermistances : les thermistances \u00e0 coefficient de temp\u00e9rature n\u00e9gatif (CTN) et les thermistances \u00e0 coefficient de temp\u00e9rature positif (CTP). Parmi eux, la valeur de r\u00e9sistance des thermistances NTC diminue lorsque la temp\u00e9rature augmente, tandis que la valeur de r\u00e9sistance des thermistances PTC augmente lorsque la temp\u00e9rature augmente ;<\/span><\/li>\r\n \t<li style=\"font-weight: 400\"><b>D\u00e9tecteur de temp\u00e9rature \u00e0 r\u00e9sistance (RTD)<\/b><span style=\"font-weight: 400\"> d\u00e9tecte la temp\u00e9rature par le biais des variations de la r\u00e9sistance du m\u00e9tal. La pr\u00e9cision de mesure de la temp\u00e9rature du RTD est plus \u00e9lev\u00e9e que celle des deux pr\u00e9c\u00e9dents, mais son prix est \u00e9galement plus \u00e9lev\u00e9.<\/span><\/li>\r\n<\/ol>\r\n<h2 style=\"font-size: 20px\"><b>3. Comment fonctionne un capteur de temp\u00e9rature ?<\/b><\/h2>\r\n<span style=\"font-weight: 400\">Les diff\u00e9rents types de capteurs de temp\u00e9rature fonctionnent diff\u00e9remment, mais leur principe de base est le m\u00eame : mesurer la chaleur et la convertir en un signal \u00e9lectrique.<\/span>\r\n\r\n<span style=\"font-weight: 400\">Pour plus d'informations sur le fonctionnement des thermocouples, consultez notre article : <\/span><span style=\"color: #ff0000\"><a style=\"color: #ff0000\" href=\"https:\/\/lorentzzi.com\/fr\/thermocouple-types-everything-you-need-to-know\/\"><span style=\"font-weight: 400\">Types de thermocouples : Tout ce qu'il faut savoir<\/span><\/a><\/span><span style=\"font-weight: 400\">.<\/span>\r\n\r\n<span style=\"font-weight: 400\">Les thermistances et les r\u00e9sistances thermiques (RTD) fonctionnent sur le m\u00eame principe et, comme indiqu\u00e9 ci-dessus, lorsque la temp\u00e9rature change, la r\u00e9sistance change. En mesurant la r\u00e9sistance et en observant sa courbe en fonction de la temp\u00e9rature, nous pouvons facilement obtenir la valeur de la temp\u00e9rature.<\/span>\r\n<h2 style=\"font-size: 20px\"><b>4.
