What is a pneumatic schematic diagram?

A pneumatic schematic diagram serves as a visual representation of how various components in a pneumatic system are connected and how they function together. It includes symbols and lines that depict components such as valves, cylinders, actuators, and air supplies, outlining the flow of pneumatic fluid throughout the system. This type of diagram is essential for understanding the system's design, facilitating troubleshooting and maintenance by clearly illustrating the relationships between components and their operational roles.

The other options describe important aspects related to pneumatic systems but do not specifically capture the essence of what a pneumatic schematic diagram represents. Safety measures, troubleshooting steps, and component selection are all critical elements of working with pneumatic systems, but they pertain to different aspects of system operation and maintenance rather than the graphical representation of component integration and functionality that a schematic diagram provides.
