Abstract

The present application shows a sensor (1, 25) for measuring a heat flux comprising: a body (2, 26) adapted to act as a heat sink for conducting and absorbing heat, with a thermal conductivity largerthan 10 W/(m-K) and a heat capacity largerthan 18 J / K with on a measurement side (3, 27) an absorptive heat flux sensor (9, 33) operable to absorb thermal radiation and a reflective heat flux sensor (10, 34) operable to reflect thermal radiation, characterised in that both sensors substantially equally sensitive to convective heat flux, and characterized in that the sensor (1, 25) comprises a heating member (12, 47) in heat conducing contact with the body (2, 26) for heating the body to a predetermined temperature or at a predetermined power, and a temperature sensor (11, 45) that is thermally coupled with the body for measuring the body temperature, wherein the heat flux sensors have a substantially similar field of view between 1.511 sr and 311 sr.
