Abstract
A device is provided for measuring the intensity of a radiative flux and optionally also a convective flux, including a thin support made from an insulating material; a thin continuous strip of meandering shape made from a first conducting material; a series of discontinuous deposits made from a second conducting material having a thermoelectric power different from that of the first material and a high electric conductivity, the whole of the deposits and of the associated underlying strip portion forming an elementary thermocouple and having, in the transverse direction with respect to the direction of extension of the strip, a width which varies between its two ends, the variation in width being in the same direction for the successive deposits along the strip; and a coating with high emissivity intimately covering at least the successive deposits. The device may also include a heat conducting layer.
