Le MS-57 de premi\u00e8re classe est un capteur d&rsquo;irradiance solaire \u00e0 incidence normale directe (DNI). \u00c9galement appel\u00e9 pyrh\u00e9liom\u00e8tre, il sert de capteur de r\u00e9f\u00e9rence pour les op\u00e9rations de routine sur un suiveur solaire. Le MS-57, r\u00e9sistant aux intemp\u00e9ries, est sensible au rayonnement solaire dans la gamme spectrale de 200 \u00e0 4\u00a0000 nm et fonctionne dans les conditions les plus extr\u00eames, \u00e0 des temp\u00e9ratures comprises entre -40 et 80 \u00b0C.

La p\u00e9riode de r\u00e9\u00e9talonnage recommand\u00e9e peut \u00eatre \u00e9tendue \u00e0 5 ans, contre 2 ans g\u00e9n\u00e9ralement pour les autres mod\u00e8les de capteurs du march\u00e9. La stabilit\u00e9 \u00e0 long terme de la r\u00e9activit\u00e9 du capteur est inf\u00e9rieure \u00e0 0,5 % sur une p\u00e9riode de 5 ans, ce qui le rend unique.<\/p>\n<p>Les pyrh\u00e9liom\u00e8tres MS-57 sont fabriqu\u00e9s de mani\u00e8re uniforme, avec un contr\u00f4le qualit\u00e9 et une \u00e9valuation des performances rigoureux. Pour chaque capteur, la variation de temp\u00e9rature est mesur\u00e9e et valid\u00e9e par un rapport de mesure fourni avec le capteur.
