Method and apparatus for measuring the surface temperature and emissivity of a heated material

METHOD AND APPARATUS FOR MEASURING THE SURFACE TEMPERATURE AND emissivity MATERIAL HEATER. SAID UNIT INCLUDES RADIOMETER 1 AND BLACK BODY HEATER 2 arranged symmetrically A NORMAL SURFACE MATERIAL 3. HEATER IS ISSUED TWO DIFFERENT QUANTITIES OF RADIATION AND ENERGY emissivity MATERIAL IS DETERMINED FROM THE VALUES DETECTED BY rADIOMETER, THE TWO VALUES TEMPERATURE COOLER AND RATIO OF REFLECTION FOR DISTRIBUTION PARTNERS AUDIT MATERIAL, FOR AND THE TEMPERATURE MEASUREMENT OF SURFACE MATERIAL. APPLICATION TO MEASURE THE TEMPERATURE OF STEEL PLATE PLACED IN AN INDUSTRIAL FURNACE.
