Abstract

Dispositif de contrôle de la densité d'un gaz à l'intérieur d'un récipient sous pression. Un élément de compensation 24 est placé entre l'élément extensible 14 entraînant l'aiguille et ladite aiguille d'un manomètre commercial connu en soi; il est dimensionné de façon à compenser la variation de position de l'élément extensible provenant de la variation de pression due à la température du gaz. Installations de commutation et aux appareils de coupure isolés au SF6 .
