Objectives

This course aims to provide students with a basic knowledge base of Industrial Automation. In particular, it is the objective of this UC to present and develop knowledge in the area of sensors and actuators (electrical, pneumatic and hydraulic) as well as the components necessary for its use. It is intended that students acquire the ability to: dialogue with specialists in each area, to understand the associated symbology, to make choices, technically and scientifically grounded among the various solutions that may be prefigured in the face of a given problem.

Learning outcomes and competences

By the end of this course, the student will be able to:

• Identify sensors, control equipment, and actuators used in automation systems;
• Specify and select the different automation components;
• Know the international symbology associated with automation components;
• Describe the mode of operation and applicability of the various equipment used in automation systems;
• Design solutions using pneumatic, hydraulic and electromechanical drive technologies;
• Interpret pneumatic and hydraulic circuits.

Teaching methods and learning activities

This course has theoretical classes in amphitheatre and theoretical-practical classes in the laboratory. The lectures are based on the presentation of the subjects of the program, supported by audio visual means and should be apprehended by students through complementary study activities and conceptualization. The theoretical-practical classes, taught in different laboratories are intended to give students an insight into the sensors and actuators used in industry.
In the Instrumentation Laboratory, students will have the opportunity to assemble and test different types of sensors, as well as to read them through computer-based data acquisition systems.
They will also be able to see different types of electric motors as well as the associated protection and control components.
In the pneumatic laboratory they will proceed to the simulation, assembly, and testing of pneumatic and electro-pneumatic circuits.
Finally, the Hydrostatic Transmissions Laboratory will also have the opportunity to test hydraulic systems.
In addition to these activities, and outside of school hours, students will perform a research and selection of sensors and actuators for a specific application.
There will be a visit to a company to get in touch with real industrial environement.

Eligibility for exams

To be admitted to exams, students have to be enrolled in the course and not exceed the absence limit allowed in the General Evaluation Rules of FEUP.
It will also be considered the frequency of the students who have attended the UC during the last 2 years.

Calculation formula of final grade

The final classification of ordinary students is based on two written tests (PE1 and PE2) with equal weight and a research paper (TRB). ">These components are evaluated from 0 to 20, having the tests a weight of 80% and the work 20%.
">PE1 - Individual written test, without consultation, to be carried out in the middle of the semester, on the matter of sensors;
PE2 - Individual written test, without consultation, at the time of examinations, focused essentially on the matter of actuators; ">NOTE that although this test does not include theoretical part of sensors, you can include calculations associated with this matter.

">TRB - Work on selection of sensors and actuators for a given application in a group (maximum of 4 students), to be presented in the practical class of the week from April 30 to May 4.


">Final classification = 0.4 * PE1 + 0.4 * PE2 + 0.2 * TRB

">IMPORTANT NOTES:
">- Failure to complete the work corresponds to a grade of 0 for the purpose of calculating the final grade.
">- Access to PE assessment tests as well as completion of the work requires the attendance of the course unit (except for students who, according to the FEUP rules, enjoy special status that exempts them from class attendance).
- The passing of the course requires a minimum grade of 8.0 values ​​in the average of the two tests, PE1 and PE2. ">Thus, students whose tests result in scores equal to or higher than 9.5 values ​​but do not meet this minimum grade, will be assigned the final classification of 9.0 values.
">- Students who have been attending but have not obtained approval after the normal time can take a PE written test at the time of appeal corresponding to the overall subject, which will replace the components PE1 and PE2, maintaining the classification obtained at work.
Final classification (resource) = 0.8 * PE + 0.2 * TRB

Examinations or Special Assignments

Not applicable.

Internship work/project

Not applicable.

Special assessment (TE, DA, ...)

Students with special status may choose to attend the Course as if they were ordinary students, by submitting themselves to the norms of their evaluation.
Alternatively, students with special status must complete a global test consisting of a written test (80%) and an oral test (20%). However, in order to have access to the oral test, they must have a written exam grade of 8 or higher.

Classification improvement

Students wishing to obtain an improvement in grading may, at the time of appeal, submit a written test (PE) on the overall subject of the UC, which will replace the components PE1 and PE2. The final grade is obtained according to:

Final grade (improvement) = 0.8 * PE + 0.2 * TRB

The classification of the TRB work performed is maintained.
