As an outcome from the subject, the students should be able to understand, design and organize the experimental activities which are usually carried out regularly in the University laboratories, in the Industry as well as in the Research Institutes.

The students attending this subject should be acquainted with basic knowledge of: mathematics and physics; basic analysis of electrical circuit and fluid-dynamics; mechanics, thermodynamics and heat-transfer. In more details, the student must review the following topics (with reference to the Three-year Degree in "Energy Engineering" of the "Politecnico di Torino"): - Fourier series (Analisi II - 22ACIMK, 22ACILX); - Electrical Potential. Condensers. Resistors. Inductors. Ohm's law. RC and RL electrical circuits. Joule effect. Time dependent Electromagnetic field. (FISICA II - 20AXPMK, 20AXPLX, 20AXPMQ) - Mass conservation and Energy conservation laws. Bernoulli's Theorem. (Termodinamica applicata e trasmissione del calore - 05IHQMK, 10IHQMO) - Heat transfer mechanisms and laws: Conduction, Convection and Radiation. (Termodinamica applicata e trasmissione del calore - 05IHQMK, 10IHQMO) - Electrical components and electrical connections. C.C. Electrical circuits. Dynamic electrical net. A.C. Electrical net. ( Elettrotecnica/Macchine Elettriche -17AULMK, 17AULLS)

The main subject topics of the theoretical and applied lectures are: 1. International System of Measurements (SI) (L 1h ) 2. Measurement Methods and Experimental Errors (L 2h) 3. Statistical data analysis (L 6h - AL 3h) 3. System Dynamic Models (zero, first and second order) and Fourier analysis (L 2h - LAB 1h) 4. Basic Electrical Principles (Bode Plot, Analogical and Numerical Filters) (L 3h - LAB 1h) 5. Data Acquisition Systems (DAQ) (L 7h - AL 2h -LAB 14h) 6. Instrument connections and Noise protection (L 1h - LAB 1h) 7. Temperature measurement (L 5h - LAB 1h) 8. Pressure measurement (L 5h - LAB 1h) 9. Flow measurement (L 3h - LAB 1h)

L’insegnamento rientra nell’a.a. 2025/26 nella sperimentazione didattica per l’attivazione di un Nuovo Modello Formativo; gli studenti riceveranno informazioni dettagliate nella prima lezione dell’insegnamento

Lectures (L 35 h): they regard the course topics, the student is kindly invited to review the topics listed in the pre-requirement section Applied lectures (AL 5h): During the applied lectures the student solves practical exercises concerning the design of an experimental layout, the choice of a sensor, the design of a measuring chain and the setup of a Digital Acquisition System. Laboratory Lectures (LAB 20h): The students will work with virtual laboratory based on a notebook, Arduino Uno board and shields. Virtual instruments like Oscilloscope, Wave Generator, Spectrum Analyzer and Digital Filters will be simulated by means of software that are based on the netbook sound-card. The Arduino Uno Board will be used like a DAQ to perform simple experiments.

Exam: Computer-based written test in class using POLITO platform;

Attended results. The exam want to check the capability of the student to design a measuring chain by selecting suitable transducers and properly setting a DAQ, and to post-process the measured quantities. Therefore, it checks the student knowledges about the following topics: - capability to select of a proper transducer in accordance to the characteristics of the physical quantity under investigation; - capability to configure the acquisition chain and set the acquisition parameters (sampling frequency, trigger type, Anti-aliasing filter); - capability to critically analyze and post-process the measured data (uncertainty estimation). The exam consists of: written test Written exam - Part 1 (1h) (30 points) The student must answer 30 multiple choice questions regarding all the topics covered in class. For each correct answer 1 point is awarded. No penalty is applied for the wrong answer. Students must be connected to the Politecnico Platform from the Politecnico classroom via their notebook. Allowed material: Calculator, pens and a clean sheet of A4 paper. Written Exam - Part 2 (40 min) (36 points) The student must provide: - an open answer regarding Temperature, Pressure and Flow measurement (16 points); - an exercise focused on DAQ setting (20 points) Evaluation Criteria: The Written test - Part 1, is passed when the students provided at least 50% of the correct answers in the multiple choices test (equal to a mark of 15/30). Otherwise the exam is failed. Written test - Part 2 will be corrected if the Written test - Part 1 has been passed. The Written test - Part 2 is passed when a mark higher or equal to 18/30 is obtained. The final mark of the exam is the algebraic mean between the mark of the written tests part 1 and 2. The exam is passed when the final mark is higher or equal to 18/30. Mark equal to 33/30 will be registered as 30/30 with honors.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
