Course contents:

The course is divided into three main parts. The first is dedicated to common types of sensing instruments and their principles of operation. Students will get acquainted with electric signals, characteristics of sensors, temperature sensors, pressure sensors, measurement of mechanics and physical properties of fluids, RC circuits, noise filters, and discrete input elements of automated systems. The second part is dedicated to actuators and drives. Students will learn about construction and operation principles of motors (DC and AC), motor control via power modulation, selection of motor for specific applications, and also about motorized actuators such as valves and pumps. The third part is dedicated to the basics of work with programmable logic controllers.
