Abstract

The temperature of media surrounding the heat source can be done by a non-contact measurement. Since it is a non-contact measurement, there will be a distance between the measuring instrument and the surface of the object measured in temperature. It is necessary to identify the relationship between measurement distances to measurable temperature readings, both theoretically and experimentally. The main problem that will be solved through this study is how much temperature changes occur due to the difference in position between the temperature gauge against the heat source object so that a model of temperature distribution is obtained in the medium around a heat source, as a function from distance to source. The purpose of this study was to determine the relationship between temperature and distance from the heat source. Research methods included library studies, physics-mathematical analysis of radiation heat transfer processes, experimental tests in the form of media temperature measurements around heat source objects for various distances. The experimental data was then processed by regression analysis, namely Least Square Method, to have the best model for temperature distribution. The result of this study revealed that the model based on radiation heat transfer state that the fourth power of temperatures at any point is inversely proportional to the square of the distance of that point to the heat source. The model obtained from this study turned out to be in accordance with the actual circumstances at a considerable distance from a heat source that is between 4 cm and 10 cm.
