Abstract

Based on the Kirchhoff´s law, an experimental apparatus was configured and fabricated to facilitate accurate emissivity and temperature measurements at medium-high temperature. The apparatus consists of four parts: the sample heating system, optical receiving system, signal amplifying and controlling system, and display system. In order to validate the experimental device, the temperature and emissivity of SUS 201 is measured between 823K and 1373K at 1.5μm. The estimated uncertainty of temperature measurement is better than 0.3%. An instrument for practical temperature measurement can be developed according to the measuring principle.
