The invention concerns a device (10) for measuring exchanges of amounts of heat in non-stationary operational conditions comprising an elongated housing (11) having one measuring end (12) closed and one connecting end (13) and a central cavity (14). The central cavity (14) contains a measuring cell (15) and electrical connection members (15). The housing (11) is extended by a hollow finger (17) which contains partly at least the measuring cell (15) which consists of a sensitive heat flux measuring element (18) sandwiched between a first heat conducting component (19) and a second heat conducting component (20). The contact surfaces of the heat conducting component (19, 20) are each coated with a gold film, so as to produce an intimate heat conducting bond with the sensitive heat flux measuring element (18).
Le dispositif (10) pour la mesure des échanges de quantités de chaleur en régime non stationnaire comporte un boîtier (11) de forme allongée ayant une extrémité de mesure (12) fermée et une extrémité de raccordement (13) ainsi qu'une cavité centrale (14). La cavité centrale (14) contient une cellule de mesure (15) et des organes de raccordement électrique (16). Le boîtier (11) se prolonge par un doigt creux (17) qui contient en partie au moins le cellule de mesure (15) qui se compose d'un élément sensible thermofluxmétrique (18) pris en sandwich entre une première pièce thermiquement conductrice (20). Les surfaces de contact des pièes thermiquement conductrices (19, 20) sont revêtues chacune d'une couche d'or, de manière à réaliser une liaison thermique intime avec l'élément sensible thermofluxmétrique (18).
