Practical Applications of Pyrometers When describing different types of pyrometers in Chapters 9 and 10 it was assumed that they operate in ideal conditions . Pyrometer readings, which are measurements of the true target temperature, Tt , are strongly influenced by real, practical, industrial operating conditions as shown in a simplified way in Figure 11 .1 . These measurements, which must account for target emissivity, E (Tt) or E,L (T), in the environment of the surrounding walls of temperature, Tom with emissivity, cw(TW), or, sxw(TW ), are taken in the presence of polluted atmosphere of temperature, Ta , having the equivalent...
