Sensor and actuator systems II

Abstract

Design and application of physical sensors, actuators and telemetry.

Objective

The student will learn about the market availability, technology, specifications, constructive design and application areas of passive sensors for physical measurements. An overview of sensor and actuator systems as well as remote-control and telemetry systems is provided. With this knowledge the student will be able to select the appropriate sensors and actuators for mechatronics problems.
