Abstract

In general, measurement error, including a precision error and a bias error, is defined as the difference between the true and measured values. Moreover, measurement error is also necessarily included in the temperature measurement using IR radiometer; however error estimation for IR radiometer has not been investigated yet. In the present study we discussed several primary factors on a measurement error and estimate a qualitative error pertaining to IR radiometer using the uncertainty analysis method based on ANSI/ASME PTC 19.1 - 1985. Detailed clarification of measurement error is important to develop a practical temperature measurement using IR radiometer. It was newly revealed from the uncertainty analysis utilized here that the measurement using IR radiometer is available in obtaining several radiative quantities. In addition, from a series of thermal visualization using IR radiometer, the relation between friction energy and a surface temperature is clarified to tribology behavior of the surface.
