Schematic Diagram Symbols Pneumatic Cylinders

By | June 28, 2022



Ah, schematic diagrams – the beacons of visual structure in our lives! For anyone working with a complex pneumatic system, a well-designed schematic diagram is an absolute must. And while many of the symbols we use in these diagrams may seem like hieroglyphs to the uninitiated, each has a specific purpose. Today we’re going to delve into the mysterious world of pneumatic cylinder symbols.

First, let’s start with the basics: a pneumatic cylinder is any device powered by pressurized gas (usually air) to move or actuate something. If your design includes a pneumatic cylinder, then you’re likely to see a symbol similar to this:

This symbol is typically found on schematics that involve cylinders, and is used to indicate the location of a power source connected to that particular cylinder. In some cases, the symbol may also include a secondary line indicating the port for exhaust gases.

In addition to a power source indicator, there are a few other symbols related to pneumatic cylinders. One such symbol looks like this:

This symbol typically appears on schematics involving the use of multiple cylinders, and generally indicates how the cylinders interact with the surrounding environment. For example, it may indicate the direction of airflow between the cylinders, or show where exhaust gases should be directed.

Another symbol that might appear is this one:

This symbol is sometimes referred to as a piston rod limit switch, and is generally used to indicate a switch or sensor which is used to monitor the position of the piston rod within the cylinder.

Finally, let’s take a look at this symbol:

This symbol, which is generally used in diagrams involving the operation of pneumatic machines, works to indicate the type of cylinder being used. Typically, this symbol will contain a number which corresponds to the type of cylinder in question.

To wrap things up, it’s important to remember that these schematic symbols serve an important purpose in helping us make sense of complex systems. By familiarizing yourself with the various symbols, you can ensure that your designs using pneumatic cylinders are correctly represented on a schematic diagram. Happy designing!
