Instrumentation and Sensors

Automation and Computer Systems
  • ApresentaçãoPresentation
    The scope of this course includes the study of sensors, technologies and test and measurement equipment. The fundamental concepts of Metrology are also taught, with corresponding practical application, through a strong laboratory component. The need to use Metrology then arises naturally throughout the developed work. Topics of signal analysis in time and frequency are also taught, which allow to understand the characteristics of the quantities to be measured, the difficulties of the process, and measures that can be adopted to mitigate these difficulties. Hence, it allows the student to approach measurement systems in an integrated way.

  • ObjectivosObjectives
    This unit aims to provide an introduction to sensors, technologies and equipment for testing and measuring of the field. The fundamental concepts of Metrology are also taught, with corresponding practical application, through a strong laboratory component. The key skills to be developed are:   1. Familiarization with sensors, technologies and equipment; 2. Familiarization with the concepts of Metrology, and its application to data acquisition processes; 3. Familiarization with the typical test equipment of the area: multimeters, signal generators, Oscilloscopes; 4. Knowledge of time and frequency signal analysis techniques 5. Familiarization with power factor compensation and circuit resonance 6. Ability to analyze the frequency of elementary circuits, and to apply filters to measurement processes
