Learning outcomes
|
The aim of the course is to introduce students to the basic principles of measuring non-electrical quantities. Students will gain an overview of the basic concepts in the field of metrology, i.e. the measurement chain and its most important components, measurement uncertainties and errors and the measurement methods used. They will also learn in more detail about the principles of selected types of sensors used in industrial automation practice, their static and dynamic characteristics and method of use. Measurements of temperature, pressure, position, velocity and acceleration, level, flow will be carried out at the technological workplaces of the industrial automation laboratory.
After completing the course, the student demonstrates knowledge in the field of measurement of selected non-electrical quantities, basic concepts in metrology and principles of selected types of sensors. The student is able to orientate himself/herself in the technologies used for measuring non-electrical quantities, to choose the appropriate method of their measurement and to select a suitable sensor.

Assessment methods and criteria
|
Oral examination, Written examination, Home assignment evaluation
During the semester and in the final exam, the student must demonstrate an understanding of the solved problems. The specific requirements will be communicated to the students by the teacher in the first week of the semester. Active participation in the exercises is required, including the development of all assigned tasks and the submission of the semester work.
