Course detail

Technical Measurement

FSI-VTM Acad. year: 2025/2026 Winter semester

The subject is first focused on basic facts from the field of metrology. Since metrology is a very large field, only elementary and introductory information is given in this subject. For a broader understanding of the context, it is necessary to start from the recommended literature. Subsequently, students are introduced to the basic properties of measuring devices and preparations that are used in the measurement of the technical quantities described below. An overview of these quantities follows from the list of lectures. The teaching of this subject is supplemented by laboratory exercises on selected topics, their list is given in the overview of laboratory exercises.

Entry knowledge

Basic knowledge of physics, mathematics, statistics, mechanics, electrical engineering and automation is assumed, at the level of completed subjects within the previous secondary school study, or previously completed university study subjects.

Rules for evaluation and completion of the course

The laboratory exercise is completed by a credit (it is awarded in the 13th teaching week). To obtain it, 100% participation in exercises, activity in exercises and elaboration, submission and teacher recognition of protocols (reports) from all prescribed laboratory exercises is required. Further details are communicated to students at the beginning of the semester. Obtaining a credit is a necessary condition for participation in the exam. The exam consists of a written part followed by an oral interview. In the written part, the student will process five assigned questions. In the oral part, the orientation in the studied issues is examined. The evaluation of the written part, the oral part and the overall evaluation of the exam is given by the classification scale according to ECTS.


Controlled participation in lessons: Controlled participation in lessons: 100% attendance at seminars is required. In case of absence, the student is obliged to compensate the lessons.

Aims

Students are introduced to modern issues of technical measurements. Some broader facts falling within the theory of metrology are also mentioned. An overview of the basics of technical measurements, basic terms, quantities, units, laws and standards is presented. The categories of metrology, the metric convention are mentioned, the national metrological system of the Czech Republic is analyzed and gauges are discussed in more detail. Special attention is paid to measurement errors and, above all, to uncertainties. Uncertainties are described in detail, including in terms of their calculation. Particular emphasis is placed on getting to know the methods of measuring individual technical quantities and measuring devices and preparations, which the student will encounter during classes at FSI and, above all, future technical practice. The above also refers to the acquisition of knowledge about data collection, their processing, also with the use of modern hardware and software technology.

The aim of the subject is to teach students to apply the knowledge gained from measurement and, in the context, from metrology in solving various technical problems in industrial practice.
