Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)
Learning and skills development in the following fields of industrial instrumentation:
1. Principles of temperature, flow, pH, conductivity and turbidity measurement. Applications of these measurement principles in the industrial area and identification of the advantages and disadvantages of different measurement solutions.
2. Operation and main types of control and position valves: their characteristics, sizing and selection according to the applications.
3. Introduction to field networks.

Demonstration of the syllabus coherence with the UC intended learning outcomes
Theoretical classes:
It consists in exposing the syllabus of the course.
Practical classes:
In practical classes students will solve problems that will accompany the course of theoretical classes.
Laboratory classes:
Students will perform measurements, calibrations and other essays related to the theoretical and practical content of the course unit and this activity is complemented with problem solving
Teaching methodologies
Distributed assessment with final exam
Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes
Frequency in the subject in terms of the laboratory component is ensured by the execution and delivery of reports of laboratory work, within 1 week after completion of work (except exceptional situations defined by the laboratory teacher). The evaluation of the theoretical-practical component is ensured by the final written assessment of the course or by the continuous assessment, formative and / or summative, carried out in the classroom context. In order to pass the continuous assessment by tests, in addition to the average grade of the 2 tests must be greater than or equal to 10, the grade in any of them must be greater than 6 values.
The final written exam of the course takes place on the dates set by the Pedagogical Council. This exam is without consultation and students can only use a scientific calculation machine, without programming skills and without graphic skills, being the use of mobile phones a condition of cancellation of the test.
Assessment methodologies and evidences
The written evaluation of the theoretical-practical component has a weight of 60% in the final grade and is carried out in continuous assessment mode (2 tests) or by final exam. The laboratory evaluation (L) has a weight of 30% in the final grade. The minimum grade in any of the evaluation components, written or laboratory, is 10 points.
The classification of the laboratory component is individual, depending on the preparation that the student makes before the laboratory work and the classification of reports delivered within the stipulated time. Student performance (AD) in the classroom also contributes a 10% weight in the final grade.
In situations where the faculty deems it necessary, final grades higher than 16 may have to be defended in oral tests. If the student does not attend these oral exams their final grade will be 16 points. This may have exceptions for students on mobility (Erasmus).
The final grade is calculated according to the following formula:
NF = 0.6% EF + 0.3% L + 0.1% DA
EF- average of 2 tests or final exam
L- laboratory classification
DA- student performance rating
It is expected to perform problems and presentation of assignments where student performance is also evaluated, and this performance is quantified with a maximum of 10% of the final grade.
Rules for taking tests:
• Upon request, it is mandatory to present an identification document during the tests.
• Only written tests are accepted in EST Setúbal test / exam notebooks.
• Leaving the room can only take place 30 minutes after the start of the test / examination and implies the definitive delivery of the test, and the entry delay may under no circumstances exceed 15 minutes.
• During the tests, calculating machines with graphic or alphanumeric capacities can only be used if the teacher authorizes it.
• During the tests is not allowed the handling or display of mobile phones (which should be turned off) and other electronic equipment, being the use of any such equipment reason for the cancellation of the test.
Students who pass continuous assessment will only be able to earn a grade in the FEED EXAM.
NOTE: Upon the consent of the RUC, a student's continuous or written examination may, in exceptional situations, be based on the development of an instrumentation project, followed by discussion, and oral student evaluation.
Attendance system
In accordance with the rules in force at the institution.
