<p>PURPOSE:To securely measure the distribution of the surface temperature of a material to be measured, which has a longitudinal shape and which is always continuously fed in the eccentric condition, by selecting a radiation thermometer, which measures the relatively accurate temperature, and accurately obtaining the surface temperature of a material to be measured opposite to the radiation thermometer lines on the basis of the temperature measurement data. CONSTITUTION:Radiation thermometers 11a-14e are arranged in the periphery of materials 30, 32 to be measured so as to form radiation thermometer lines 11-14, and a position detecting means 19 for detecting the relative position alpha, beta of the eccentric materials 30, 32 to be measured is arranged so as to detect the radiation thermometer, which is positioned nearest the center alpha, beta of the materials 30, 32 to be measured, and temperature distribution of the materials 30, 32 to be measured is, obtained by using the measurement data by radiation thermometers 11b, 12c, 13c and 14b.</p> |
