Textbook on ‘Pneumatic Systems and Circuits -Basic Level in the SI Units’
By Joji Parambath
The book describes the topics on compressed air generation and contamination control, pneumatic actuators, and control valves, in detail. Many single-actuator control circuits are presented. Further, the book presents the maintenance, troubleshooting, and safety aspects of pneumatic systems. The book uses units in the SI system.

[Continuation of an earlier post Comparison of Power Transmission Systems (Part 1)]
Choosing the right and efficient form of energy for the drive system in the industry is not an easy task. Its selection depends on various factors. Table 1.1 gives a comparison of different forms of energy medium based on some essential criteria, as mentioned.
Table | Comparison of different power transmission systems
| Criteria / Power system | Electrical | Hydraulics | Pneumatics |
| Linear force | Using rotary to linear conversion devices | Using cylinders – Large forces due to high pressure | Using cylinders – Limited forces due to low pressure |
| Rotary force (Torque) | Using electric motors | Using hydraulic motors | Using air motors |
| Overloading | A severe problem | loadable until standstill with relief valves | Loadable until standstill |
| Sensitivity to temperature variations | Insensitive | Sensitive | Relatively insensitive |
| Leakage | Lethal accident risk at high voltages | Loss of energy and environmental fouling | Loss of energy |
