The classification of measuring errors and classes of the measuring accuracy. The calculation of measuring errors. The classification of measuring devices and their parameters. Electromechanical meters. Electron meters. Digital meters. Electrotechnical calibration and verification of measuring instruments, an overview of the supervisory requirements. Measurement of electrical and non electrical values. Overview of measuring systems working with computers. Measurements of Automation Systems: temperature, pressure, flow, level, density, moisture and viscosity measurements. Proximity sensors, contact sensors.

General aim

The graduate of the course has knowledge about the most important measurement units of electrical and non-electrical values, about different electrical measuring devices and their fields of usage, meter’s parameters and classification, basic measuring principles of electrical values, symbols used in meter’s scales, the classification of measuring errors and accuracy classes, the verification and calibration requirements for electro-technical measuring instruments. The student is familiar with the constructure, operating principle, characteristics and fields of usage of automation sensors and measuring devices.

Aim

1. Student describes different measuring instruments and their fields of usage.
2. Selects suitable measuring instruments guided by measured electrical values.
3. Student selects suitable sensors guided by measured non-electrical values.
4. Evaluates accuracy parameters for the results of measurements.
