The article presents the simulation results of noncontact temperature measurements uncertainty (in the measurement range of 350…750 °C), which were performed using dual-channel radiation thermometers through a cloud of clinker dust in the cases of different dust concentrations. It is shown that the use of dual-channel spectral ratio radiation thermometers is more efficient compared to single-channel measuring instruments. According to the simulation study the best results in terms of the uncertainty level of dual-channel radiation thermometer were obtained by the using in its design the couple of a wide-band and a narrow-band measuring sensors. It is proven that in order to cover the entire temperature range of 350…750°C with an acceptable level of uncertainty, it is advisable to utilize the dual-channel radiation thermometer in the combined single-channel and dual-channel mode of operation.
