Objetivos

Learning and skills development in the following industrial instrumentation domains:
1. Principles of temperature, level and flow measurement. Applications of these measurement principles in the industrial area and identification of the advantages and disadvantages of different measurement solutions;
2. Functioning and main types of control valves and positioners: their characteristics, dimensioning and selection according to the applications.

Métodos de ensino e atividades de aprendizagem

The teaching methodology is based on lectures and practical lessons that have expository nature and practice in the classroom, respectively. This methodology is complemented by a laboratory component (labs) that consists on the execution of 7 laboratory works.
The evaluation has a continuous component whose weighting in the final classification is 30% and a final examination component whose weighting in the final classification is 70%. The laboratory component includes an individual evaluation component with a weight of 10% and the remaining 10% results from the evaluation of laboratory works. There is also an ongoing assessment component associated with an individual research work supported by the tutorial guidance component of UC, which weighs 10% on the student's final grade.

Obtenção de frequência

The minimum grade in continuous assessment by tests is 8 values in any of the tests.
In situations where the faculty considers it necessary, final grades higher than 16 may be defended in oral exams. If the student does not attend these oral exams, his final classification will be 16 values.
In the evaluation by final exam or tests, questions related to the laboratory component of the UC are foreseen.
Once approved in continuous assessment, the student will only be able to improve the grade during the appeal period. Attendance and approval in the laboratory component (execution of all work, delivery of results and reports) is mandatory for approval in the UC.

Fórmula de cálculo da classificação final

The final grade is calculated according to the following formula:
NF=0.7*EF+0.2*LAB+0.1*DSA;
EF- average classification of the 2 tests or the classification in the final exam; LAB- laboratory classification (minimum 10 values); DSA- performance in the classroom (includes laboratory).
In the case of assessment by exam, the grade of the EF component corresponds to the classification obtained in this test, and, as mentioned, the attendance and approval in the laboratory component is mandatory for approval in the UC.

Melhoria de classificação

Once approved in continuous assessment, the student will only be able to improve the grade during the appeal period.
