We present the results of the comparative analysis of the characteristics of the domestic-made heat flux sensor PTP-1B with widely used foreign-made area sensor FOA-020. The conditions are typical to the ground-based thermovacuum research and testing of space technology products, conducted in the absence of validated converter-sensors of the aggregated heat flux within the density range of up to 2000 W/sq. m and a spectral range of 0.2 - 20 µm.
Experimental studies were performed in a thermal vacuum chamber of the experimental stand TEC-2.5 at the temperature of its internal surfaces of 20 0C. Recommendations regarding the possible use of the PTP-1B sensor as a working instrument of measurements in monitoring and diagnostic systems during the processes of ground testing of space technology objects are given
