It is noted that for the efficiency enhancement of solar energy converters it becomes necessary to measure exactly the temperature and temperature difference. The requirements of normative documents exceed the metrological parameters of the standardized temperature sensors. Therefore, the challenge of thermometers and temperature difference meters accuracies can be solved by errors correction within simple and practically suitable procedure.
Cyber-physical systems as dispersed systems based on interacting networks of physical and computing components provide new functionalities for improving the quality of measurement processes. It is proposed to carry out automated operational setup of metrological parameters of these systems measuring channels during operation basing on the code-controlled measures-imitators.
The accuracy of temperature difference meters depends on technological parameters of controlled processes. The meters of temperature difference can be constructed for operation in a wider temperature range. Their accuracy is determined by the non-identity of the sensors transformation functions.
