Symbols of Electronic Sensors, Transducers, Detectors...

The transducers, sensors and electrical and electronic detectors are elements that are activated by the energy delivered by a system and that in turn deliver another type of energy to another different system. The transformed energy may be physical, chemical or biological origin.
