Sensors and Transducers

System

Many engineering applications and systems depend on accurate measurements and monitoring. Transducers are fundamental to the measurement process, consequently the study of different types of transducers, how they operate and how their output signals can be processed, is essential knowledge for engineers.

Features

The TK2942-001 Tranducers Kit introduces students to the concepts and understanding of common transducer devices and standard signal conditioning methods via 28 excellent practical assignments. It comprises the Measurements Package TK2941M, the Electro-mechanical Transducers Kit TK2941E, the Heat Transducers Kit TK2941H, the Light Transducers Kit TK2941L, the Power Supply 01-100 and includes all leads and accessories.

 Students carry out the experiments as specified in the printed manual. Hand-held multimeter and oscilloscopes are used to measure the characteristics of the sensors.

The target group is made up of commercial apprentices and students of automatization and control engineering. The course offers experiments at an intermediate level for vocational colleges and undergraduate level.
