Item Study of the metrological characteristics of conductivity sensors(Lviv Politechnic Publishing House, 2022) Bubela Tetiana; Moiseieva ViktoriiaConductivity 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. Studies have been carried out for various objects: non-carbonated mineral water, fruit juice, and tap water.Item Study of the primary converter-object system for electrochemical devices(Lviv Politechnic Publishing House, 2021) Bubela Tetiana; Yatsuk Vasyl; Fedyshyn Tetiana; Ivakh Roman; Krachunov HristoТhe problem of creating electrochemical devices and the issues that arise in the system of the primary converter object of control are considered. Low-resistance (salt solutions) and high-resistance (sugar solutions) objects were selected as the subject of study. To solve the problem, we have applied the method of impedance spectrum analysis with EIS Spectrum Analyzer software, which performs modeling on the Levenberg–Marquardt algorithm. Substitution schemes in different frequency and concentration ranges of studied objects were synthesized. This enables appropriate corrective action to minimize the impact of adverse events in the system while monitoring the quality of solutions – non-electrical nature objects – by electrochemical devices.
