          Infrared measurements<\/strong><\/p>\n<\/div>\n

          \n

          Infrared temperature meters are used to determine the surface temperature of the tested object. The optical system of the instrument detects the radiation that is emitted, reflected and transmitted, then gathers them and focuses it in the detector. The electronic system converts the optical data into a temperature value. To increase the precision of measurement and facilitate targeting, the device is equipped with a laser pointer.<\/p>\n

          Infrared radiation<\/strong><\/p>\n

          Infrared radiation is generated by the movement of electrons inside the atoms of a given material. It is electromagnetic radiation with a wavelength in the range of 780 nm\u20261 mm. It is emitted by any material with temperature above 0\u00b0K (-273.15\u00b0C). The emission increases with increasing temperature, whereas the wavelength decreases.<\/p>\n

          Emissivity factor<\/strong><\/p>\n

          It is a parameter that determines the ability of a material to emit infrared radiation. Its values are in the range 0\u20261.<\/p>\n

            \n
          • A value equal to 1 is the emissivity of a black body that absorbs all radiation.<\/li>\n
          • A value equal to 0 is the emissivity of a white body (reflecting 100% of radiation).<\/li>\n<\/ul>\n

            Each object has its own emissivity factor, depending on the type of material, surface roughness, viewing angle, wavelength and temperature.<\/p>\n

            The D:S<\/strong>\u00a0ratio<\/strong><\/p>\n

            The D:S ratio (distance to spot) determines the relationship between\u00a0the distance of the pyrometer<\/strong>\u00a0from the tested object and\u00a0the diameter of its circular<\/strong>\u00a0field of view<\/strong>, from where it collects the radiation. The tested area becomes larger as the meter moves away from it, i.e. the share of the tested object\u2019s area in this field decreases. Hence, the smaller is the measured target, the smaller should be the distance to it. Therefore, the D:S ratio has a significant influence on the accuracy and precision of the temperature reading.<\/p>\n
