The basic composition of actuators

- Nov 29, 2017 -


In the Process control system, the actuator consists of two parts: the actuator and the automation regulator. The automatic adjusting mechanism can directly change the parameters of the production process by executing the components, so that the production process meets the predetermined requirements. The actuator accepts the control signal from the controller to convert it to the output of the drive regulator (such as angular displacement or linear displacement output). It also uses appropriate actuator components, but requires different regulatory mechanisms. Actuators are installed directly in the production site, sometimes with harsh working conditions. The ability to maintain normal work directly affects the safety and reliability of the automatic control system.


A device that accepts control signals in an automated control technology tool and exerts control over the controlled object. Actuators are divided into pneumatic, electric and hydraulic actuators according to the drive energy used in 3 categories.
