The work is directed on accuracy increasing of the thermodynamic temperature measurement of heated objects by their own thermal radiation, utilizing no more than two monochromatic channels for the spectral density of radiance measurement.
A method for measuring wind speed by the trajectory of an acoustic package under the influence of air flows in the boundary atmospheric layer is developed. Model equations for measurement components of wind speed evaluation are ob- tained. For each of the components, an equation for the combined standard uncertainty is written, sensitivity coefficients are calcu- lated for input quantities, and uncertainty budgets are constructed. The last can serve as the basis for creating a software tool for measurement uncertainty evaluation.
Conductivity measurement is a universal method of process control. Measurement is fast and straightforward, and most modern sensors only require little maintenance. The measured conductivity value is applied to obtain different assumptions about what happens in the substance, so such measurements are relevant when controlling technological processes and products in various industries (e.g., food, pharmaceutical). The main metrological characteristics of sensors for measuring conductivity LDL100, LDL200 are analyzed in the article.
