Objectives

This Curricular Unit aims to develop fundamental skills in measuring quantities and signals of current interest in the various fields of engineering and in conceiving and designing electrical and electronic devices and equipment for measurement and instrumentation.

Thus faced with a problem of measuring an electric or non electric quantity, the student should be able to select, define and evaluate themeasurement method and the most appropriate components, equipments, procedures and programs, as well as to design the respective measurement chain or instrumentation system.

It is also intended that the activity performed by students under this course promotes knowledge of business and professional activity in Electrical Engineering in the field of Measurement, Instrumentation and Sensors.

Learning outcomes and competences

In order to achieve the above mentioned aim, students should develop the skills outlined below.
Specific technical skills:

• mastery of technical concepts of measurement, instrumentation and use of their technologies;
• development of reasoning in analyzing and solving measurement problems systematically and accurately;
• development of design, implementation and test skills of instrumentation for specific applications.

Other skills:

• development of skills for experimental team work by performing laboratory and project work;
• development of written, oral and multimedia technical communication skills.

Learning outcomes are assessed from the capabilities to:

• explain and analyze operating principles of electronic devices in typical situations of measurement and instrumentation
• properly use electronic and virtual instruments in experimental measurements of electrical quantities and signals and evaluate possible sources of error
• apply knowledge on sensors and instruments for measuring non-electrical quantities and signals of current interest
• interpret the specifications of the major components of the measuring chain, in particular conditioning circuitry, analog-digital converters and the most important non-electrical transducers
• characterize a measurement problem and prepare requirements and technical specifications
• conceive, design, implement and validate measurement systems and instrumentation for specific applications
• organize and prepare technical documentation related to a method or instrument and apply methods for evaluating the quality of measurement.

Lectures, in which the theoretical concepts are presented, and application problems are solved and discussed
Laboratory, in which several laboratory assignments will be given and executed in class with the instructors support.

Eligibility for exams

Laboratory classes are mandatory and subject to the regulations regarding the maximum number of allowable absences.

If students miss an assignment (even if the absence is adequately justified) they have to do it in another time duly authorized by the professor and supervised by the technician responsible for the laboratory.

Students have to attain a minimum grade of 9.5 in 20 marks in the laboratory work assessment for it to be considered completed.

Calculation formula of final grade

The final grade is the average of two grades, corresponding to the theorecital and laboratory components of the course.

There will be two written tests, with questions on both the theoretical material of the course, and other questions on the laboratory component.

The grades for each of the components are evaluated as follows:

1 -Theoretical component  (50%):

• Average of the grades of the theoretical parts of the two written tests (40%)
• Attendance bonus in preparation of class (5%)
• Attendance bonus in consolidation of knowledge from class (5%)

2 – Laboratory component (50%), divided into:

• Average of the grades of the laboratory reports (20%)
• Average of short final quizzes of practical work (10%)
• Average of the grades of the laboratory parts of the two written tests (15%)
• Teacher avaluation, including attendance bonus, for attendances above the mandatory 75% (5%)

Minimum passing grade: at least 9.5 marks in 20 at each of the two components mentioned above.

Examinations or Special Assignments

There will be two written tests, one in November and the other on the first week of January. The resit test wil be held in February.

Each test consists of two groups of questions, one on the theoretical part of the course, and the other on laboratorial part.

The laboratory part of the course will consist of five laboratory assignments and one laboratory project. The first sessions of the semester will be occupied with an introduction to the instrumentation on the workbench, and an introduction to the software that will be used in the course.

Internship work/project

A small project of a complete measurement chain will be assigned.

Special assessment (TE, DA, ...)

Laboratory work is compulsory to all students. Students with a special status will also have a chance to do the assignments (at an adequate time for them). Nevertheless, they will be assessed just like the other regular students.

Classification improvement

Of the theoretical component through the completion of evaluation tests at a later appropriate period for that purpose.

Of the laboratory component by performing all laboratory activities of this component in the following school year.
