Σύνοψη

Pneumatics has for some considerable time been used for carrying out the simplest mechanical tasks, but in more recent times has played a more important role in the development of pneumatic technology for automation.
In the majority of applications compressed air is used for one or more of the following functions:
• The use of sensors to determine status of processes
• Information processing
• Switching of actuators by means of fmal control elements
• Canying out work
Before the 1950s pneumatics was most commonly working as a medium in the form of stored energy. During the 1950s the sensing and processing roles developed in parallel with working requirements. This development enabled working operations to be controlled using sensors for the measurement of machine states and conditions. The development of sensors, processors and actuators has led to the introduction of pneumatic systems.
In parallel with the introduction of total systems, the individual elements have further developed with changes in material, manufacturing and design process.
