Credits 9
Hours 72
Period I
Language ENG

It is required that the student knows the fundamental concepts of mathematical analysis, physics, mechanics, fluid dynamics, thermodynamics and electromagnetism.

Learning outcomes
The course enables students to acquire basic knowledge on measuring instruments for mechanical and thermal quantities , providing the elements necessary to the understanding of the measurement process , the interaction between the object of measurement and the meqasuring system, static and dynamic characteristics of measuring systems, the uncertainty, the working principles of sensors and transducers, their use in the laboratory and in industry
The student will learn through examples and exercises in the classroom and the laboratory , how to apply this knowledge to experimental research , product development , testing of machines and systems , quality and process control , diagnosis and management and maintenance of products and production departments , as well as monitoring , evaluation and technical assistance
The discussion of application examples in various industries and of various components and products will provide the student with a clear awareness of the transversal nature of the science of measurement in the wider multidisciplinary context of engineering , through a constant reminder to cross-cutting aspects of measurement systems and technologies

Contents (lectures, 62 hours) The course presents the basic knowledge of mechanical and thermal measurements and testing methodologies. The measurement principles of the quantities of interest for industrial applications are shown through theoretical lectures and practical examples. General concepts on measurement systems and procedures. Instrument utilization in industrial application and on-line testing. Static and dynamic calibration. Elements of signal analysis and digital data processing, including basics concepts for analysis in the frequency domain. Traditional and innovative systems for the measurement of: dimension, displacement, strain, velocity of solids, velocity of fluids, acceleration, force, torque, power, pressure, flow rate, temperature. Basics on data acquisition systems and digital devices (sampling, quantizing, coding, main devices). Laboratory experiences (10 hours) Static Calbration, dynamic calibration, application of strain gages, signal acquisition and analysis using LabView.

Development of the examination
The examination consists in an oral discussion of the subjects of the course and of the laboratory exercises. 3 questions will be posed (maximum 4 in case of doubts in the evaluation): one on general metrological characteristics, one on the measuring principles of instruments and one on signal acquisition. The students may also prepare and discuss a report on the experiments performed during the lectures.

The student, during the oral examination, will have to demonstrate to have the fundamental knowledge of mechanical and thermal measurements, data acquisition and digitalization and testing methods. In order to pass the exam with positive results, the student will have to show an overall knowledge of the course contents, which will have to be exposed with sufficient and correct use of technical terms. The maximum score will be achieved by demonstrating a deep knowledge of the course contents presented with a fully appropriate technical approach.

Score in a scale with 30 levels (e.g. 27/30) based on knowledge and capacities demonstrated by the student and measured according to the Learning Evaluation Criteria.

For each question posed to the student, a score in the scale with 30 levels will be assigned. The final overall score will correspond to the average of the scores for each single question. The Laude will be assigned to the students that, having achieved the maximum score, will also demonstrate an outstanding knowledge in the discussed topics.
