Course detail

Measurement Technique

FSI-XMT-KAcad. year: 2019/2020

The course introduces the students to the principles of computer-supported measurement systems. Possible errors in measurements performed by these systems, their corrections and methods of interpretation of the obtained data are explained.

Learning outcomes of the course unit

After the course, the students are able to design simple measurement systems made of standard components, for example for measurements of length, temperature, location etc., to evaluate the obtained data and to analyze the possible faults of the measurement chain.

Prerequisites

Students are expected to have basic knowledge of metrology, electrotechnics and PC skills.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
According to the possibility of teaching can be organized lectures for students by practitioners and excursions to companies focused on activities related to the course content.

Assesment methods and criteria linked to learning outcomes

Course-unit credit is conditioned by 100% attendance at laboratory practicals and approved reports. Examination has a written and an oral part and tests student’s knowledge and his/her ability to apply it in practice.

Language of instruction
