Accuracy Advancement of Non-Contact Temperature Measurement with Differential Technology

摘要：

Generally, accuracy of non-contact temperature measurement is not high because of the effects of ambient temperature and surface thermal emissivity of measured target. Differential measurement technology is measuring both temperature of a reference target and a measured target with the same temperature measurement device. As ambient temperature, rays and surface thermal emissivity of heating unit have nearly the same effects on two targets,actual measurement error of reference temperature actual value can be used to correct temperature error of measured target. When working environment of reference target and measured target are basically the same, differential measurement can eliminate most measurement error caused by environmental factors. This method is mainly used in noncontact temperature measurement requiring high accuracy.
