Ces PRT ont une pr\u00e9cision de &lt;0,012\u00b0C et une stabilit\u00e9 \u00e0 court terme de &lt;0,007\u00b0C.<\/p>\n<p>Pour obtenir les meilleures performances en mati\u00e8re de stabilit\u00e9 et de r\u00e9p\u00e9tabilit\u00e9, l'\u00e9l\u00e9ment de d\u00e9tection est sp\u00e9cialement con\u00e7u pour prot\u00e9ger le fil de d\u00e9tection en platine de la contamination \u00e0 haute temp\u00e9rature.

Cette sonde de haute qualit\u00e9 est enti\u00e8rement conforme aux crit\u00e8res ITS-90 pour les thermom\u00e8tres de r\u00e9f\u00e9rence.

Bien que moins pr\u00e9cis qu'un PRT de r\u00e9f\u00e9rence primaire, il offre n\u00e9anmoins une pr\u00e9cision et une fiabilit\u00e9 consid\u00e9rables pour de nombreux usages scientifiques et industriels.<\/em><\/p>\n<p><em>Le principe de fonctionnement d'un PRT de r\u00e9f\u00e9rence secondaire est bas\u00e9 sur la propri\u00e9t\u00e9 que la r\u00e9sistance \u00e9lectrique du platine change avec la temp\u00e9rature. Ces thermom\u00e8tres utilisent une bobine de fil de platine pur, mesurant avec pr\u00e9cision les changements de r\u00e9sistance \u00e0 diff\u00e9rentes temp\u00e9ratures. Ces mesures sont ensuite converties en valeurs de temp\u00e9rature \u00e0 l'aide de formules normalis\u00e9es.<\/em><\/p>\n<p><em>Les PRT de r\u00e9f\u00e9rence secondaire sont \u00e9talonn\u00e9s par rapport aux thermom\u00e8tres de r\u00e9f\u00e9rence primaire. Cet \u00e9talonnage garantit un degr\u00e9 \u00e9lev\u00e9 de pr\u00e9cision et de reproductibilit\u00e9. Ils sont souvent utilis\u00e9s dans les laboratoires, les processus industriels et les applications m\u00e9t\u00e9orologiques o\u00f9 des mesures de temp\u00e9rature fiables sont essentielles, mais o\u00f9 la pr\u00e9cision extr\u00eamement \u00e9lev\u00e9e des thermom\u00e8tres de r\u00e9f\u00e9rence primaires n'est pas requise.<\/em><\/p>\n<p><em>L'une des principales caract\u00e9ristiques de ces thermom\u00e8tres est leur stabilit\u00e9 et leur fiabilit\u00e9 sur une large gamme de temp\u00e9ratures. Ils sont robustes et durables, ce qui permet de les utiliser dans des environnements exigeants. En outre, les outillages de r\u00e9f\u00e9rence secondaires sont plus \u00e9conomiques que leurs homologues primaires, ce qui en fait une option int\u00e9ressante pour de nombreuses organisations qui ont besoin de mesures de temp\u00e9rature pr\u00e9cises sans avoir \u00e0 supporter le co\u00fbt d'un outillage de r\u00e9f\u00e9rence primaire.<\/em><\/p>","protected":false},"excerpt":{"rendered":"<p><strong>Caract\u00e9ristiques :<\/strong><\/p>\n<ul>\n<li>Sonde de r\u00e9f\u00e9rence abordable<\/li>\n<li>Plage de temp\u00e9rature : -200\u00b0C \u00e0 670\u00b0C<\/li>\n<li>Pr\u00e9cision : &lt;0,012\u00b0C \u00e0 0,01\u00b0C<\/li>\n<li>Stabilit\u00e9 \u00e0 court terme : &lt;0,007\u00b0C<\/li>\n<li>Coefficient de temp\u00e9rature 0,003925 \u03a9\/\u03a9\/\u00b0C<\/li>\n<li>Enti\u00e8rement conforme aux crit\u00e8res ITS-90 pour les thermom\u00e8tres de r\u00e9f\u00e9rence<\/li>\n<li>Bo\u00eetier en Inconel\u2122 r\u00e9sistant aux environnements difficiles<\/li>\n<\/ul>","protected":false},"featured_media":5383,"template":"","meta":[],"product_brand":[],"product_cat":[129,69,115],"product_tag":[312],"class_list":["post-5382","product","type-product","status-publish","has-post-thumbnail","product_cat-handvoelers","product_cat-kalibratoren","product_cat-referentie-thermometers-en-sondes","product_tag-temperatuur","first","instock","shipping-taxable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Secundaire Referentie PRT: Additel AM1751<\/title>\n<meta name=\"description\" content=\"Additel AM1751 Secundaire Referentie PRT: nauwkeurige en betrouwbare temperatuurmetingen.
