Summary
The aim of the subject is to deepen knowledge of measurement methods in the field of thermo-technical quantities. The student will get acquainted with the whole measuring chain from the sensor to the evaluation device, with the principles of analog and digital measurements, including evaluation of measurement uncertainty. In more detail, the subject deals with temperature, pressure, humidity, volume and mass flow measurement and gas analysis, both in laboratory and operating conditions.
Learning Outcomes of the Course Unit
Student will be able:
- to characterize the elements of the measurement chain and understand their function,
- to know methods and sensors for measuring temperature, pressure, velocity, flow rate, humidity, gas analyzes,
- select the appropriate sensor and signal processing method for the measured quantity,
- to design the measurement method and determine uncertainty of the measurement.
