Pneumatics Chart

Well, I finally finished all of the pictures and tables for my book and I thought I’d share one of them here. I must make a confession: I use pneumatics a lot, specify components for systems, troubleshoot machines with air cylinders etc. but I really never understood the diagrams completely until doing the research for this book.

This chart doesn’t have every symbol on it but I was limited by having to put everything on one page. Hopefully some of you will find this useful.

The biggest thing I learned when making this chart was that every little symbol has a meaning (duh!) and what the 4/2, 5/3 designation really meant. As I mention in the book formal training by vendors has been very helpful to me in my career. I learned a lot about sensors, intrinsic safety, vision, PLCs, motor and motion control from sales training before actually designing with them. I worked for distributors and manufacturer’s representatives in the early 1990s before embarking on my integration career and the training was very helpful. Unfortunately pneumatics was never part of my training so I had to pick it up on my own.

Hope everyone has a great holiday!
