De plus, cette \u00e9quation calcule la r\u00e9sistance en fonction de la temp\u00e9rature ; ce qui est l\u2019inverse des utilisations les plus courantes : temp\u00e9rature en fonction de la r\u00e9sistance.<\/p>\n

      Pour convertir la valeur de r\u00e9sistance du RTD en temp\u00e9rature, on est oblig\u00e9 d\u2019utiliser une \u00e9quation quadratique du 2e degr\u00e9, qui est, en quelque sorte, la r\u00e9ciproque de l\u2019\u00e9quation Callendar-Van Dusen, mais uniquement pour les temp\u00e9ratures sup\u00e9rieures \u00e0 0\u00b0C.[\/vc_column_text][mk_image src=\u00a0\u00bbhttps:\/\/legacy.rdccontrol.com\/wp-content\/uploads\/2014\/09\/tempurature-calculation-04.gif\u00a0\u00bb image_size=\u00a0\u00bbfull\u00a0\u00bb align=\u00a0\u00bbcenter\u00a0\u00bb margin_bottom=\u00a0\u00bb40″][vc_column_text css=\u00a0\u00bb.vc_custom_1512735388384{margin-bottom: 0px !important;}\u00a0\u00bb]Pour les temp\u00e9ratures inf\u00e9rieures \u00e0 0\u00b0C, l\u2019\u00e9quation Callendar-Van Dusen est trop complexe \u00e0 r\u00e9soudre, aussi l\u2019emploi des approximations successives s\u2019impose[\/vc_column_text][mk_image src=\u00a0\u00bbhttps:\/\/legacy.rdccontrol.com\/wp-content\/uploads\/2014\/09\/tempurature-calculation-05.gif\u00a0\u00bb image_size=\u00a0\u00bbfull\u00a0\u00bb align=\u00a0\u00bbcenter\u00a0\u00bb margin_bottom=\u00a0\u00bb40″][vc_column_text css=\u00a0\u00bb.vc_custom_1512735421246{margin-bottom: 0px !important;}\u00a0\u00bb]La table suivante nous propose des valeurs calcul\u00e9es avec l\u2019\u00e9quation de Callendar-Van Dusen[\/vc_column_text][mk_table el_class=\u00a0\u00bbrdc-metal-table\u00a0\u00bb]\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
