Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

•Describe methods and standards adopted in primary, secondary and working Metrology laboratories, for the
realization and materialization of physical quantities.
•Describe methods and perform calibration of measuring instruments.
•Develop calibration procedures, quantify errors and calculate the measurement uncertainty in calibration.
•Develop and implement automated measuring instruments calibration projects.

Syllabus

•Fundamentals of Metrology: International national and regional organizations; units and standards of
measurement, International Vocabulary of Metrology.
Measuring Instruments: characteristics and specifications;
•Traceability, calibration certificate, comparability and inter-comparability of measures.
•Statistics for metrology: statistical distributions applied in metrology; methods of regression.
•Calibration and uncertainty: components of uncertainty calculation of expanded uncertainty in calibration;
application to instruments measuring electrical quantities, pressure and temperature.
•Metrological aspects in quality systems: metrology in quality systems; certification; metrology laboratory in the
industry; accreditation of testing / calibration laboratories; considerations NP ISO / IEC 17025 and ISO 9000.
Procedures of calibration of measuring instruments.
•Automation of measurement calibration and its uncertainty calculation.

Demonstration of the syllabus coherence with the UC intended learning outcomes

The curricular unit´s contents are structured, regarding its suitability for the intended learning outcomes. Therefore, each subject approaches fundamentals concepts and required tools in the field of measurement instrumentation in order to provide the theoretical knowledge and practical procedures that will give the students the ability to specify measuring instruments, select the appropriate standard in specific measuring instruments calibrations, set conditions to perform calibration tests and calculate the calibration uncertainty. Also will provide the expertise to interpret and issue calibration certificates. As a complement, the approach to documents in the quality area will allow students to recognize the role of metrology in companies, particularly in industry. Using the techniques of signal acquisition and use of software learned in other courses students will have the ability to develop and implement automatized calibration and uncertainty calculation projects.

Teaching methodologies

Lectures including
• Exposure of contents and critical reflection through discussion with the students;
• Case study and practical application exercises.
Laboratory classes including
•Experimental work;
•Use of real measurement instrumentation devices.
Assessment includes
•Two individual tests or exam carried out at the end of the course (70%).
•Experimental works and reports (20%).
•Realization of a Metrology project: automating the calibration of a measuring instrument and respective
uncertainty calculation (30%)

Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes

Regarding the intended learning outcomes, the curricular unit is structured in lectures approaching fundamentals and practical procedures that will provide the student knowledge and understanding of subjects and apply them in exercises designing calibration procedures with specific applications to different physical quantities. The laboratory classes provide practical skills development through the implementation of real experimental assembly and data analysis for the uncertainty calculation. The written tests or final exam carried out by the students will allow them to demonstrate their ability to solve problems and their knowledge and description of standards and calibration methods.
