Content of the lectures is devoted to measurement methods and principles used in modern sensors for measurement of temperature, pressure, flow and total volume, level and for measuring of the composition of liquids and gaseous mixtures. Students will also learn about the signal processing. Laboratory exercises are focused on thermography, pressure transducers, heat measurement, gas and vapor concentration measurement in the atmosphere, including measurement of combustion emissions, sensor signal processing and wireless sensors. According to individual assignments, the students process a technological measurement project. Last update: Kopecký Dušan (10.08.2018)
