Abstract

Dc-operated radiation thermometers, due to their high-speed response, simple and rigid optical and electrical systems are widely used in industry and science. Practically, in all metrology laboratories the realization and dissemination of the temperature scale (by means of radiation temperature) is carried out using the dc-operated transfer standard radiation thermometers. Therefore, the actuality of the accurate characterization of all aspects of the pyrometer system is evidently clear.<br /> This paper describes the systematic error contribution of the gain non-linearity of well-designed preamplifiers in the signal processing of the dc-operated radiation thermometers.
