Abstract
Le dispositif suivant l'invention concerne une sonde pour la détermination des transformations de phase qui se produisent dans les métaux, généralement à des températures élevées, au cours du refroidissement ou du chauffage. Grâce à un circuit résonnant 6 approprié, opportunément protégé par une structure refroidie 5 résistante à la chaleur 2 mais perméable au flux électromagnétique, la sonde est sensible aux variations de certaines caractéristiques physiques liées aux transformations de phase qui se produisent dans les métaux. (CF DESSIN DANS BOPI)
