Application Aluminium Optical temperature measurement during extrusion, forging and rolling of aluminium

Application note Aluminium Optical temperature measurement of aluminium The acquisition of thermal radiation for measuring the temperature of aluminium is one of the most difficult measuring tasks in radiation thermometry. On the one hand, aluminium is a very poor source of radiant heat, so that infrared radiation is extremely low, especially at low temperatures. On the other hand, the surface properties and thus the emissivity of aluminium can vary considerably. Ordinary pyrometers react extremely to such influences, so that no reliable temperature measurement is possible. Therefore, suitable...
