Description :
The Modular System for the Study of Sensors includes a wide range of units that
include different electronic components designed to control the signal produced by the transducers (Sensors and Actuators) on the one hand, and to evaluate and quantify it on the other hand. Therefore, the following units have been developed to show the fundamental principles of the different sensors and actuators and to understand in a practical way how to process the signals which they produce.
This unit is common for the different test modules type and can work with one or several modules. All elements are included in a metallic box.
