Measurements

Metrology systems (quantities, international system of units SI, definitions and realization of etalons of physical quantities, dissemination, traceability, calibration, conformity assessment).

Fundamental principles of measurement and information content of signals, mathematical model of the measurement system measurement scales, measurement strategies.

Measuring accuracy and uncertainty (absolute and relative errors, measurement result, true value, statistic analysis, measurement uncertainty), signal conditioning.

Measurement of electrical quantities (voltage, current, power, resistance, capacitance, inductance, frequency, phase, power factor, frequency spectrum, …).

Application of basic measuring instrumentation (ammeter, voltmeter, wattmeter, oscilosscope, vector analyser).

Measurement of non-electrical quantities (temperature, humidity, preasure, force, lenght, noise, …).

The course introduce basic knowledge of metrology and measurements of technical quantities. Objectives of the course are:

a) to study the fundamentals of metrology and metrological systems, Si units, connections with other fields of science;

b) to introduce the basic principles of measurement of most important quantities in engineering, properties of measurement signals;

c) to learn the approaches and methods of measurement of basic electric quantities and caracteristics of measurement transducers;

d) to extend the concepts of measurement and comprehension and interpretation of the measurement results;

e) to study the meaning of statistic and analysis of measurement uncertainty;

f) to prepare for laboratory practices and work;

g) to learn the security requirements and protection when using measurement instrumentation in connection with power supply.

Lectures, laboratory tutorials, solving practical tasks (problems).
