Type: article
Abstract: In the article the results of temperature measurements performed by five one-channel radiation thermometers with different spectral sensitivity characteristics under dusty environment conditions are presented. The dust influence on the random and the systematic measurement error is estimated. We examined the efficiency of two approaches of evaluating and inputting the external correction coefficients into the radiation thermometers for the purpose of minimizing the effect of the non-stationary dust cloud. It is established that the correction coefficient value used to compensate the effect of dust presence should be estimated fairly accurately (±0.04) for the specific environmental conditions. It is proved that the calculated short-time standard deviation of measurement results can be considered as an indicator of dust cloud presence in an active phase.
