Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)
The students will be able to:
1) to have the basic knowledge of metrology concepts, namely, accuracy, sensitivity, resolution and uncertainty and their application in the instrumentation and measurement areas;
2) to use analog and digital measuring instruments and to understand their operating principles;
3) to identify the mains specifications and limitations of the measuring instruments;
4) to know the working principle of measurement transducers and design electrical circuits to measure industrial quantities.

Demonstration of the syllabus coherence with the UC intended learning outcomes
The syllabus described above are consistent with the goals set for the course. Each content is working in three dimensions, theoretical, practical and laboratory so that students develop the skills of analysis, synthesis and practical implementation of circuits elementary signal conditioning interface for transducers. Apart from the above, students will have knowledge of circuits analog-to-digital and digital-to-analog used in the field of instrumentation and measurement, as well as on their selection according to specific real situations. Finally, students will be able to select techniques of signal transmission in industrial environment because of the knowledge acquired about communication networks.
Teaching methodologies
The lectures will serve to theoretical exposition of the course syllabus. The classes will have a component based on examples, in terms of applications of the contents taught in lectures, and on problem-solving and worksheets. In laboratory classes are scheduled 5 works. Approval of the theoretical and practical component is provided with the completion of course’s final written evaluation. The written evaluation has a weight of 50% in the final grade, and is constituted by a final exam. The lab evaluation has a weight of 20% of the final grade, with mandatory submission of reports. The minimum grade in any component of assessment is 10 points. Final scores above 16 points will be defended in oral examination if considered necessary. To stimulate the spirit of learning, a work group is due with 20% weight in final grade. Last 10% evaluation comes from 5 on-line mini-tests.
Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes
The course is organized in lectures, practical classes and laboratory classes. The lectures aim to prepare students to understand the content of the subjects taught, advising references and clarify doubts. Practical classes promote problem solving illustrative of the syllabus and prepare students for laboratory applications. Laboratory classes are intended to encourage students to work independently, in the sense that they will be able to organize their thinking in order to deal with new situations. The students also have the opportunity to practice the techniques associated with the measurement principles and methods, modes of operation and specifications of the equipment used, observing in experimental context the circuits studied.
Assessment methodologies and evidences
The approval in the discipline can be obtained by continuous evaluation or by final examination.
Continuous assessment and final assessment includes a mandatory laboratory component and theoretical component.
The laboratory component consists of:
1) Execution of the five lab assignments with delivery of the respective report on the Moodle platform until the last laboratory class.
2) Execution of laboratory mini-tests, one for each laboratory work, to be carried out in the Moodle platform until the 25th of January.
3) Execution of a mini-lab project with delivery of the respective report and software until the 9th laboratory class (6th or 7th of December, according to the laboratory shift), with oral discussion in that same class.
The laboratory component is exempt from students who have attended it, with approval, in the immediately preceding academic year.
The theoretical component consists of performing two interim tests (T1 and T2) on the following dates at 6:30 p.m.: T1 on December 5, and T2 on January 23.
The continuous assessment grade (N) is calculated according to the following formula:
N = 0.5 * T + 0.2 * L1 + 0.1 * L2 + 0.2 * L3, with T, L1, L2 and L3> = 10 values,
at where:
T: Mean of the scores of the two interim tests (T1 and T2) or grade of normal period exam;
L1: Note of the five laboratory works;
L2: Note of five laboratory mini-tests;
L3: Note from the lab mini-project.
The minimum mark of all continuous evaluation components (T1, T2, T, L1, L2 and L3) is 10 values.
The final exam evaluation consists of the normal period exam. Anyone who does not have the approval in the theoretical component of the continuous or final evaluation can recover in the examination of the time of appeal. Anyone who has passed the theoretical component of the continuous assessment may improve the grade in the examination of the resource period. The minimum grade of the resource exam is 10 points.
All exams and interim tests are written, individual and without consultation.
If the teacher responsible for the discipline deems it necessary, final classifications of more than 16 values will have to be defended in oral tests. If the student does not attend the oral test, his final grade will be 16 points.
