Abstract:
Device for the measuring of exchanges of amounts of heat in non-stationary operational conditions, these conditions being a low level dynamic buried in an environment highly disturbed by considerable thermal fields, the said device comprising an extended housing (11) provided with a central cavity (14), a measuring end (12) and a connection end (13), the measuring end (12) being closed and the central cavity (14) containing, on the one hand, a measuring cell (15) and, on the other hand, electrical connection members (16), the said measuring cell comprising at least one thermal flux sensitive element (18) sandwiched between a first heat conducting component (19) and a second heat conducting component (20), characterized in that the said first heat conducting component (19) is in contact with at the least one surface of the said housing (11), and in that the said second heat conducting component (20) is insulated from the said housing and constitutes a constant heat capacity.
