Summary
The course is aimed at deepening of knowledge in the field of metrology of thermal-technical quantities. Students will become familiar with the entire measurement chain from the sensor to the evaluation unit, with the principles of analog and digital measurement including the evaluation of measurement uncertainties. For more detail, students are introduced to the measurement of temperature, pressure, humidity, volumetric and mass flow and analysis of gases, both in the laboratory and in the industry.
