Basic Structure Of Actuator

type
In the process control system, the actuator is composed of two parts: an executive mechanism and an automatic adjustment mechanism. The automatic adjustment mechanism directly changes the parameters of the production process through the actuators, so that the production process meets the predetermined requirements. The actuator accepts the control signal from the controller and converts it into the output of the drive adjustment mechanism (such as angular displacement or linear displacement output). It also uses appropriate actuators, but the requirements are different from the adjustment mechanism. The actuator is installed directly on the production site, sometimes the working conditions are harsh. Whether it can maintain normal operation directly affects the safety and reliability of the automatic adjustment system.
structure
A device in an automated control technology tool that accepts control signals and controls the operation of the controlled object. According to the driving energy used, the actuators are divided into three categories: pneumatic, electric and hydraulic actuators.
