ABSTRACT:
A sensor for measurement of an energy flux and in particular a sensor for measurement of a heat flux or measurement of visible or infrared radiation. The energy flux sensor includes deposits of a first metal in the shape of plates on each of the faces of a substrate, metal-coated holes of the same first metal through the substrate joining one face to the other and surface elements of another metal having thermoelectric properties in relation to the first metal, placed in the thickness of the substrate. This sensor, alone or associated in series with other sensors, makes it possible to measure the thermal properties of certain construction materials, insulating materials in particular. It also makes it possible, when covered with an absorbing coating, to measure visible or infrared radiation.
