This course aims to study the digital measurement chain, the associated electronics, and the different types of sensors.

Contents:

Chapter 1. The digital measurement chain and associated electronics.

• General information on measurement, the overall structure of a complete measurement chain: acquisition, processing, output. 
• Description of the components of a measurement chain and electronic circuits:

1.  Components of a chain, the sensor (types, characteristics), conditioning of the sensor (potentiometric assembly, push-pull assembly, bridge assembly), 
2. Circuits for conditioning the measured signal (isolation amplifier, instrumentation amplifier (notion of voltage in instrumentation mode), etc.). signal (isolation amplifier, instrumentation amplifier. filtering, linearisation, analog-to-digital conversion (ADC), digital-to-analog conversion (DAC), digital data processing (programmed logic, storage, and display), 

Chapter 2. Sensors: metrological characteristics

• Definitions and general information on sensors, electrical and non-electrical quantities,
• Different types of sensors (passive, active, digital, intelligent, composite), physical phenomena used in sensors (electromagnetic induction law, hall effect, thermoelectric effect, magneto-resistive effect magneto-resistive effect, photoelectric effect, piezoelectric effect, Doppler effect, etc.), 
• metrological characteristics (sensitivity, linearity, calibration curve, resolution, speed, response time and bandwidth, limits of use, calibration-measurement range, nominal field of use, non-deterioration of deterioration), criteria for choosing a sensor.

Chapter 3. Sensors in Industrial Instrumentation

• Classification of sensors, 

1. Temperature sensors, 
2. Position and displacement sensors, 
3. Speed and acceleration sensors, etc.
4. Force and deformation sensors, pressure, level, and flow sensors
