“…In the publications of the authiors of this chapter (Taymanov & Sapozhnikova, 2009, 2010a, 2010b, it is emphasized that the metrological self-check can be realized only on the basis of the redundancy that can be just of temporal, spatial, and informational type. The redundancy of the above types can be used separately as well as in any combination.…”

“…However, the ambient conditions of measuring instruments as well as those of living organisms are characterized by a significant level of unpredictability. Adaptive methods allow to take into account the variability of the environment (Taymanov & Sapozhnikova, 2010b). The adjustment of the insulating properties of an animal's pelt with the season increases the likelihood of survival under a changing environment, as does the active thermoregulation of measuring instruments.…”

Abstract. The paper deals with metrological tasks conditioned by the coming technological revolution that is connected with the application of cyber-physical systems (CPSs) and Internet of Things (IoT). The need for terminology standardization in this field is shown and definitions of the main terms are proposed. CPSs and IoT can be economically efficient only in case of the transition to a qualitatively new level of metrological maintenance in the course of operation. It is necessary to abandon conventional methods of periodic calibrations. Topical metrology problems with regard to multi-channel systems including the necessity to check the reliability of measurement results automatically, are formulated. A number of examples demonstrate that to solve such problems it is possible to rely on the experience gained in the development of measuring systems with the metrological self-check and on the first national documentary standards in this field.

“…The converters consist of two parts: a body (rod) and a replaceable thermocouple measuring package of one-time use. The advantages of the pyrometric method of temperature measurement include non-contactness and high speed of measurement, and the disadvantages are a high error associated primarily with the uncertainties of the blackness coefficients [6,7]. A large number of publications [2,13] devoted to solutions to reducing the uncertainties associated with the uncertainties in the blackness coefficients in pyrometric measurements.…”

Abstract. There is a scientific problem of non-contact measurement of the temperature of metal melts now. The problem is related to the need to achieve the specified measurement errors in conditions of uncertainty of the blackness coefficients of the radiating surfaces. The aim of this work is to substantiate the new method of measurement in which the influence of the blackness coefficient is eliminated. The task consisted in calculating the design and material of special crucible placed in the molten metal, which is an emitter in the form of blackbody (BB). The methods are based on the classical concepts of thermal radiation and calculations based on the Planck function. To solve the problem, the geometry of the crucible was calculated on the basis of the Goofy method which forms the emitter of a blackbody at the immersed in the melt. The paper describes the pyrometric device based on fiber optic pyrometer for temperature measurement of melts, which implements the proposed method of measurement using a special crucible. The emitter is formed by the melt in this crucible, the temperature within which is measured by means of fiber optic pyrometer. Based on the results of experimental studies, the radiation coefficient > 0.999, which confirms the theoretical and computational justification is given in the article.
