Abstract
Densimètre (10) comprenant un caisson (40) contenant un échantillon de gaz et relié à un conduit d'alimentation en gaz (26) par l'intermédiaire d'une canalisation d'entrée (42) étranglée afin de limiter l'écoulement, de manière à partiellement isoler le caisson (40) et à l'amortir contre des chocs, du bruit, des turbulences ou des variations brutales de pression d'alimentation en gaz. Une pale (110) en porte-à-faux est placée dans le caisson (40) afin de déterminer la densité du gaz selon le principe que la fréquence résonante de la pale (110) est fonction de la densité du gaz dans le caisson (40). On détermine la fréquence résonante de la pale (110) par application d'un champ magnétique généré par un ensemble circuit d'attaque (120) contre la pale (110) et par détection de la fréquence résonante au moyen d'un détecteur de vibrations (117) relié à l'ensemble circuit d'attaque (120) dans une boucle à phase asservie.
