Abstract

As a part of the studies on practical surface temperature measurement by infrared radiometer, some basic characteristics of an infrared radiometer were studied by using three kinds of sensors with different detectable wave lengths. Specimens allowable for gray body approximation such as mortar, graphite and carbon fiber composite material were tested at a practical ambient temperature of 293 K. As a result, the difference between a radiation temperature in consideration of reflection and that derived from an emissivity increased with a decrease in emissivity, and the deviation of an emissivity derived from a radiosity coefficient increased at 20 K or less in difference between a specimen surface temperature and ambient one. Each radiosity coefficient measured by each sensor also fairly agreed with each other. The deviation of a radiosity coefficient was relatively small indicating a good agreement between theoretical and experimental data, while the difference between emissivity and radiosity coefficient deviations decreased with an increase in specimen surface temperature. 3 refs., 10 figs., 1 tab.
