Structure This unit is split into three distinct sections: Section 1 Pneumatic systems Section 2 Electronic control Section 3 Programmable control. When the students have completed this unit of work they should be able to: interpret pneumatic systems and circuit diagrams describe the operation of pneumatic systems pipe-up/construct pneumatic systems have an appreciation of safety requirements when operating pneumatic systems perform calculations to determine cylinder pressure, piston force and area evaluate pneumatic systems. It is important therefore that students gain an understanding of the benefits of pneumatics as well as the obvious limitations. As a method of completing tasks it has many distinct advantages in terms of energy consumption, cost and safety. Teachers’ Introduction Pneumatics is used extensively in industry as well as in many everyday applications.
