Abstract
Thermomètre de point chaud. Il comprend un corps de matière céramique, un tube rempli d'un fluide relié par chacune de ses extrémités à un soufflet et un bras oscillant qui agit alternativement sur un premier soufflet, puis sur l'autre. Le corps de matière céramique destiné à détecter les variations de température peut se dilater et, dans ce cas, son extrémité effilée comprime une boucle formée sur le tube et provoque, en conséquence, une élévation de pression du fluide qu'il contient et impose une charge au bras oscillant qui indique la variation de température detectée par l'élément de détection. Application au contrôle de la température des spires de l'enroulement d'un transformateur refroidi à l'huile.
