The advancements in control engineering are increasingly determined by the further development of components such as controllers, amplifiers, or actuators. Among the continuous electrical amplification elements, the transductor holds an important position. Despite all its advantages, there is a certain reluctance regarding the use of transductors in control systems. This is likely due to the fact that the transductor, despite its simple construction, is exposed to a number of disturbances that need to be eliminated through appropriate sizing and special switching measures. Therefore, a more detailed understanding of the technology of this amplifying element is necessary for the designing engineer than is required when using machine amplifiers or electronic elements (with the exception of semiconductors). A properly executed control system.
