Abstract

PURPOSE:To realize the measurement for the emissivity of the subject, by sticking the plural number of the emissivity measuring elements with known emissivity epsilon onto the emissivity measuring subject, keeping the same temperature for both to measure radiation temperature TR of the radiation measuring element and radiation temperature Ts of the measuring subject, and then using the calibration curves obtained from epsilon and TR. CONSTITUTION:The stainless steel (SUS) is used for the measuring subject, and the alumite plate is used for the emissivity measuring element each. And four units of this element 1 are stuck onto surface 2 of the SUS plate equidistantly to be held until the same temperature is obtained between the element and the SUS plate. After the balance is obtained for the temperature of the both, radiation temperature TR of the element is measured by the infrared radiation thermometer. Then the calibration curves are obtained based on radiation temperature TR1-TR4 of four elements No.1-No.4 each and their known emissivity epsilon. If the measurements of the radiation temperature of SUS is TRO, its emissivity can be known as epsilon0 from the calibration curve.
