  • Number of hours

    • Lectures : 8.0
    ECTS : 0.5

Goals

This course aims at providing knowledge of the experimental measurement general principles. Active and passive sensors are presented according to underlying physics they involve. Special emphasis is given to sensors devoted to thermal measurements and velocimetry as well.

Content

1. Introduction

  • Definition of the following concepts: measurement, error, uncertainty
  • Passive sensors, active sensors
  • Linearity
  • Examples of well-known sensors (strain gauge, thermistor, thermocouples, Hall sensor, Rogowski sensor…) and physical laws associated

2. Temperature measurements and experimental evidence of one classical artefact

  • Hot/cold junctions
  • Seebeck effect
  • Full calculation of the analog signal delivered.
    A guiding visit is organized around an experimental set-up devoted to thermal transfers (Thermal platform of ENSE3). Artifact related to cold junction is demonstrated.

3. Pressure and velocity measurements

  • Optical methods (particle imaging, laser Doppler, tracers)
  • Thermal Anemometry (thermal balance, King law, emphasis on single hot wire, crossed hot wires, hot film wire)
  • Pressure-based velocimetry measurement: Euler equations and effect of compressibility, Prandtl or Pitot probes, examples of industrial sensors


Prerequisites

General background in classical physics
