Abstract
Two methods are proposed for determining the procedural error ΔT based on a comparison of the ratio and difference of the radiation signals picked up by a sensor from a primary standard and an object. Those methods, theoretical and experimental, require knowledge of the sensor conversion parameter. Both methods are shown to be correct and to give the same results. Tungsten and platinum are used as samples to show the relations the principal quantities that define the photoemission temperature measurements. These relations allow the optimum conditions to be chosen for measurement in a given temperature interval, taking into account the object and the sensor parameters.
