Ce capteur First Class Advanced offre des performances exceptionnelles. Il est class\u00e9 selon la norme CEI 61400-12-1 \u00c9dition 2.0. Il offre des performances dynamiques optimales et pr\u00e9sente les caract\u00e9ristiques suivantes\u00a0:<\/p>\n

Haute pr\u00e9cision
\n\u00c9cart minimal par rapport \u00e0 la ligne cosinus
\nExcellent comportement aux turbulences
\nSurvitesse minimale
\nConstante de distance faible
\nFaible valeur de d\u00e9marrage
\nFaible consommation d’\u00e9nergie
\nSortie num\u00e9rique<\/p>\n

Ce capteur est con\u00e7u pour mesurer la vitesse horizontale du vent en m\u00e9t\u00e9orologie, en climatologie, en \u00e9valuation de site et pour mesurer les caract\u00e9ristiques de puissance des \u00e9oliennes (courbes de puissance). Sa conception brevet\u00e9e est le fruit de longs essais en soufflerie. Ce capteur pr\u00e9sente un comportement dynamique m\u00eame en cas de forte intensit\u00e9 de turbulence, de survitesse minimale et de faibles valeurs de d\u00e9marrage. Gr\u00e2ce \u00e0 sa faible inertie et \u00e0 son \u00e9toile \u00e0 roulement \u00e0 billes, il ne n\u00e9cessite qu’une maintenance r\u00e9duite. L’an\u00e9mom\u00e8tre est \u00e9quip\u00e9 d’un chauffage \u00e0 r\u00e9gulation \u00e9lectronique pour garantir le bon fonctionnement des roulements \u00e0 billes et \u00e9viter le givrage de l’arbre et de la rainure en fonctionnement hivernal.<\/p>\n
