Training objectives
- The teaching target of the course "SENSORS FOR INDUSTRIAL APPLICATIONS" is to provide to the students the knowledge of the physical phenomena behind the operation of a wide variety of sensors and transducers with electrical output. The principles of operation and transduction, their physical model and metrological characteristics will be illustrated. The terminal part of the course will deal with digital communication protocols, typically used in SMART SENSORS (Control Area Network (CAN), Modbus®, PROFIBUS®).
The main knowledge acquired will be:
- Physical phenomena at the base of the transduction of the physical quantities under measurement.
- Operational limits and fields of application of the various types of sensors.
- Mechanisms for management and transmission of sensor outputs.
- Main digital protocols for the transmission of sensor output.
The main skills (ie the ability to apply the acquired knowledge) will be:
- Ability to analyze which type of sensor to use for a specific application.
- Ability to identify operational, documentary limits and communicate them clearly.
- Ability to select the most suitable digital communication protocol for a specific function. Prerequisites
- Basic knowledge of electricity and magnetism, current, potential difference, electrical resistance, HALL effect, Seebeck effect, and induced current. Basic concepts of physics of electronic devices (diodes, LEDs and MOSFETs) and serial digital communications.
Course programme
- Proximity sensors (mechanical, optical, inductive and capacitive)
Position and speed sensors (potentiometers, LVDTs, encoders, tachometer sensors, Hall effect sensors)
Force and pressure sensors (piezoresistive and capacitive)
Temperature and humidity sensors (PTC, NTC, thermocouples, diodes, capacitive and resistive hygrometers)
Irradiance and heat flux sensors (thermopiles and heat-flux sensors based on Seebeck effect)
Magnetic sensors and magnetometers (induction, HALL effect, magnetoresistive, MEMS, SQUID)
Chemical sensors (chemFET, chemoresistive sensors) Didactic methods
- Lectures on the blackboard with the aid of a video projector
Learning assessment procedures
- Oral exam including 4 general questions (plus any questions for clarification). For each general question a maximum score of 8 points is awarded. The exam is considered passed if the student scores more than 18/30.
