The method of estimation of influence of uneven distribution of heat flow and uneven sensitivity of sensor on the error of determination of heat flow is proposed. Experimental studies of flat semiconductor and bimetal sensors have been carried out, which can be used both as infrared receivers and as heat flux sensors. A new method of measuring the emissivity is proposed, which is a combination of the relative radiation and calorimetric methods and allows to compensate the influence of the convective component of heat exchange in the measuring cell Product Description popup.authors Vorobiov Leonid Yo.
