Variation of spatially heterogeneous radiation by coordinate-sensitive receiver

Abstract

The developed device is intended to analyze the state of thermal insulation of underground pipelines. The proposed heat flow meter uses current heating of the sensor element in the process of temperature measurement. This will improve the accuracy of temperature measurement and maintain the reference temperature measured previously using current heating. The developed device has several identical plates, each of which can receive radiation. Formulas for determining energy parameters based on calibration of a coordinate-sensitive receiver by a spatially uniform heat flow generated by an electric current are obtained.
