Method of contactless measuring the surface temperature and/or emissivity of objects

摘要

The method of contactless measuring the surface temperature and/or the emissivity of objects on the principle of scanning the infrared radiation coming out of the measured object (1) by means of, at least, two infrared radiation detectors (3,5). The particular infrared radiation detectors (3,5) are maintained at the different mean temperatures (T1, T2) by the supply of heat, while the different and independent output signals (U1, U2) of these detectors are obtained for the determination of surface temperature (To) and/or the emissivity of measurd object (1).
