In pneumatics, what does the term 'actuator' refer to?

The term 'actuator' in pneumatics specifically refers to a device that converts air pressure into mechanical motion. This process typically involves using compressed air to produce movement in a pneumatic system, allowing for the operation of machinery or other devices. Actuators can take various forms, such as cylinders or diaphragm systems, each designed to transform the energy from compressed air into linear or rotational movement.

In pneumatic systems, actuators play a crucial role in tasks such as lifting, pushing, or controlling other components of the system. Their ability to efficiently transform pressurized air into motion is fundamental to the effectiveness of pneumatic applications in industries like manufacturing and automation. This makes the role of an actuator essential in any context where pneumatic power is utilized.

Other terms mentioned, like devices that store compressed air, measure pressure, or regulate airflow, refer to different functions and components within a pneumatic system, but they do not perform the essential function of converting air pressure into motion, which is the defining characteristic of an actuator.
