Abstract: The master’s thesis is dedicated to investigating the influence of thermocouple placement on temperature measurement accuracy in industrial processes. The thesis analyzes existing methods of thermocouple placement and their limitations in temperature measurement under variable thermal environments. Based on experimental research and modeling, optimal methods for determining thermocouple placement in protective tubes have been developed to enhance measurement accuracy and stability. The research results demonstrate that the location of the thermocouple in the protective tube depends on specific characteristics of the industrial process, such as flow velocity, thermal conductivity of the medium, and its geometry. The proposed optimization methods for thermocouple placement enable improved measurement accuracy and ensure result stability regardless of changes in the environment. These findings are of significant importance to engineers and scientists working in the field of metrology and temperature control in industrial processes. They can be utilized to enhance the efficiency and reliability of measurement systems in SC reactors. Keywords: sheathed thermocouple, time constant, measurement accuracy, placement optimization.
