Symbols of Electronic Sensors, Transducers, Detectors ...

The transducers, sensors and electrical and electronic detectors are elements 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 of physical, chemical or biological origin.
