THE IMPORTANCE OF UNCERTAINTY DETERMINATION DURING TECHNOLOGICAL TEMPERATURE MEASUREMENTS

Abstract

As we know, one of the trends in the development of metrological control activities of enterprises and organizations is the calibration of measuring instruments through the assessment of measurement uncertainty. This process is an important factor to increase the accuracy of measurements, ensuring product quality, minimize the amount of waste products and increase the competitiveness of the organization. Such a parameter can be, for example, the standard deviation (mean squared error of the measurement results) or a number that is exactly divisible by it, or the width of the confidence interval. Measurement uncertainty combines several components. Some of these components can be estimated based on the statistical distribution of the results of a series of observations and characterized by their standard deviations. Considering that more than 50% of the measurements performed during technological processes are covered by temperature measurements, then we can say that the errors occurring during temperature measurements directly affect the quality of the product significantly. In the conducted research, the uncertainty in the temperature measurements performed during the technological processes was determined and the importance of determining this uncertainty was analyzed.
