Credits 9
Hours 72
Period I
Language ENG

The student should know basic cocepts of mathematics and physics as wello as elements of mechanics, fluid dynamics, thermodynamics and electromagnetism.

Learning outcomes
The course provides the students with the skills necessary for the selection and use of measuring systems for mechanical and thermal quantities used in quality control and process . In particular it provides the elements for an understanding of the measurement process , the interaction between measuring and metering system , static and dynamic characteristics of measuring systems , uncertainty . These elements are presented in the context of measuring operations aimed to determine consequent decisions . They then illustrate the principles of operation of sensors and transducers , and describes their use in the industrial context . The concepts of quality and the practical problems of control and management will be an integral part of the course .
The student at the end of the course will know the functioning of measuring systems for mechanical and thermal quantities . He will also be able to choose the measuring instrument suitable for the process of interest , considering both the uncertainty , the static and dynamic response . Finally he will incorporate measurement systems in an industrial process and perform measurements interpreting the results critically .
The student will be able to apply the lessons learned on measuring instruments in various industrial contexts , both for the quality control of products , as well as for the control of processes , wit application to multiple sectors.

The course provides knowledge on the principles of operation and the choice and use of sensors and transducers for industrial measurement of mechanical and thermal quantities, with particular reference to their application for quality. The following main parts will be developed. Classroom lessons (62 hours) 1) The concept of measurement. Functional representation of measurement instruments. Examples. 2) Static characteristics of measurement instruments. Precision, bias, sensitivity, resolution, impedance, threshold, hysteresis. Uncertainty budget according to GUM. Static calibration. Dynamic characteristics. Generalized mathematical model of an instrument. Instruments of 1st and 2nd order; response to standard inputs, periodic inputs, transients and random inputs. Frequency response functions. 3) Sensors and transducers for measurement of: displacement, deformation and strani, velocità, acceleration, force, torque, mechanical power, flow velocità, flow rate, pressare, temperature. 4) Digital acquisition systems: main architecture and analog and digital electronic components of a multichannel data acquisition system. Amplifiers, filters, AD and DA converters. All instruments are discussed highlighting: basic operation principles, static and dynamic performance, field of application, choice criteria, use of data output. Exercises/training sessions in classroom and in laboratory (10 hours) The following training sessions will be organized: 1) static calibration of a transducer in classroom; 2) one training session of measurement of dynamic quantities in classroom; 3) one training session in laboratory of informatics on the programming language Labview; 4) one training session on DAQ systems; 5) one guieded visit to the laboratories of DIISM.

Development of the examination
Oral exam composed by three questions, respectively on a) static and dynamic characteristics of instruments, b) description of a specific transducer and c) digital acquisition systems.

Knowledge of the topics, demonstrated through a clear, correct and complete oral presentation.

During the oral exam it will be evaluated the capacity to present the topic and to describe it correctly also with the support of graphics and schemes.

The maximu mark is obtained by those students who demonstrate complete mastering of the three topics, exposing them clearly, in depth and correctly by producing also schemes and graphics. The minimum mark is attributed to those students who demonstrate a sufficient knowledge of at least two of the three topics and at least a partial knowledge of the third.
