AIMS AND CONTENT

LEARNING OUTCOMES

The course provides an operational understanding of the fundamentals of measurement, including methods of static and dynamic analysis, uncertainty assessment, calibrations, components, signal conditioning and the measurement of mechanical and thermal quantities. The necessary notions of probability and statistics are provided

AIMS AND LEARNING OUTCOMES

The students will learn the general measurement principles and the physical working principles of the main measurement instruments. The students will be able to choose appropriate instrumentation technology based on the description of process properties and performance requirements. The students will be able to select the proper circuits for conditioning and conversion of analogue measurement signals, to communicate about industrial instrumentation with specialists as well as system users. Furthermore, the students will be able to evaluate the reliability of a measurement result and analyse the uncertainty associated to a given measurement chain. Finally, the students will be able to deepen their knowledge about measurement systems and instrumentation by autonomous bibliography research on books, papers or specific periodicals.

TEACHING METHODS

The module mainly structured in frontal lectures where the course topics are treated using slides and the blackboard. During the lessons, exercises and examples will be presented to facilitate the understanding of the topics. If possible, the students will carry out simple laboratory experiences.

All the course material will be uploaded on the course website using Aulaweb. Notes, slides, tables, spreadsheets and all the material available on the website is part of the course. Those students who do not attend the lectures are recommended to look at the website to check the communications and the course material.

Students with certifications of Specific Learning Disorders, disabilities or other special educational needs are advised to contact the lecturer at the beginning of the lessons to agree on teaching and examination arrangements that, while respecting the teaching objectives, take into account individual learning patterns.

EXAMS

EXAM DESCRIPTION

The examination consists of an oral test.

The questions cover both the fundamentals of measurement and the operating principles of transducers. Students will be required to answer open-ended questions concerning the methodological aspects addressed in the first part of the course, the components of measurement chains, and selected types of measurements of particular relevance to industrial engineering. Students are expected to support their explanations with equations and graphs, providing a concise and comprehensive presentation.

Students with certification of specific learning disorders, disabilities, or other special educational needs are advised to contact the instructor at the beginning of the course in order to agree on teaching and examination arrangements that, while respecting the learning objectives of the course, take individual learning needs into account.

ASSESSMENT METHODS

The oral examination is intended to verify that students are able to carry out practical engineering tasks, such as evaluating the uncertainty to be assigned to a measurement, given the technical specifications of the instrumentation used.

In addition, the questions are designed to assess students’ knowledge of the fundamental concepts of measurement engineering, their acquisition of appropriate technical terminology, and their knowledge of the basic instrumentation used in industrial contexts.

The open-ended questions will also make it possible to evaluate students’ understanding of the topics covered during the module, the clarity of their presentation, their ability to communicate results using appropriate technical language, and the critical awareness they have developed regarding the main measurement applications in the field of industrial engineering.
