The invention relates to a sensor capable of measuring the flow of heat that hits the surface 1, being in particular capable of quantifying not only the total heat flow but also its radiative and convective components. The operating principle of the sensor in reference is based on the possibility of relating the temperature difference between points 2 and 3 with the total incident flow of heat. It is further based on the possibility of cancelling out the convective component of the total heat flow by the destruction of the limit layer that forms naturally on the surface 1, by making a specified discharge of air (or another gas) pass through the disc 4, of necessity made of a porous material. The possibility of cancelling out the convective portion of the total incident flow enables, with two successive measurements, the total flows, convective and radiative, to be quantified, since the first is equal to the sum of the last two. <IMAGE>
