Execution agencies are used in every industrial sector. In the field of process automation, they are responsible for locating blades and valves to control the flow of materials, mass and energy.
The trend as an actuator for "smart field devices" is now considered part of the prior art. ^In recent times, increased functional requirements in devices, as well as connectivity to bus systems and increased visualization of process and device data; researchers in intelligent electric actuators have been developed to meet these needs and are based on word control The compound terminology with the actuator is a "smart" compact actuator.
Its functions include: continuous positioning; overload protection in the final position, no need to rely on torque closure; high protection level; long maintenance interval.
The combination of proven mechanical components and microprocessor electronics has been used to develop intelligent series actuators: compatible with fieldbus and more traditional control methods; diagnostics support and parameter setting via graphical user interface; Self-monitoring facility; fail-safe storage with technical data enabled.
