This module will build on previous topics by presenting an introduction to transducers used in both analog and digital applications. It also covers temperature, pressure, and flow transducers as well as other detection devices such as optical encoders and Hall-effect sensors. Capacitive, ultrasonic, and thickness sensors are also presented using practical and theoretical examples of industrial applications of these devices.
