Actuator basic structure
Types of
In the process control system, the actuator is composed of two parts: the actuator and the automatic adjustment mechanism. The automatic adjustment mechanism directly changes the parameters of the production process through the execution element, so that the production process meets the predetermined requirements. The actuator receives 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, and sometimes the working conditions are severe. Whether it can maintain normal work 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 applies a control function to the controlled object. Actuators are divided into pneumatic, electric and hydraulic actuators according to the driving energy used.
