Application of a multichannel radiation thermometer for increase in adequacy of non-contact temperature measurement results

In this article, the main destabilizing factors causing a method error in radiation thermometry are represented and examined. The operating algorithm of a new five-channel radiation thermometer is suggested. The numerical values of the thermometer method error for four different conditions of the radiometric chain were imitated. It is shown that this algorithm makes it possible to eliminate the influence of the background temperature and radiation coefficients automatically.
