Why Simplified Symbols

Category: 

 

The components needed to manufacture and construct pneumatic logic control circuits are readily available, reliable and have been proven in countless applications. The symbols needed to design a pneumatic circuit are few, yet until now no practical rapid symbology for the control designer existed. Most of the symbols available to the designer are too complex to facilitate clear, creative thinking, take too long to record, leave room for significant errors, and generally slow down the design process. In an effort to improve both the speed and accuracy of creative design, we offer for your consideration and use this simplified system of symbols for designing pneumatic control circuitry.
 
Basic Requirements
Before a circuit can be designed, one needs a basic understanding of the various components available and how they function. This understanding is a requirement for the successful use of any symbol. To  depict these functional concepts, graphic symbols are used.
 
Historically, pneumatic symbols have been overly detailed and cumbersome. Symbols (such as ANSI) are often used to tell a complete narrative story. The symbols of this type are difficult to use because of their complexity. The writing and the reading of them is always lengthy, robbing time from creative efforts. As a finished product they are useful, and tell a great deal about the component, pertinent or otherwise, but they were never intended for air logic control designs. To a circuit designer such symbols are a burden that can slow or derail the thought process.
 
Time-saving
What is needed is a group of pneumatic component symbols that will provide the circuit designer, both novice and professional, with a viable shorthand that will save time, yet clearly record and communicate ideas. They should be open-ended and expandable to truly represent the variety of pneumatic controls available to the designer now, as well as in the future.
 
Fast and Functional
They must be fast and easy to draw. They should be both pictorial and functional in nature to help the designer visualize the circuit, and to provide the necessary pertinent information about how components work (inputs, output, actuators, etc.). What follows is a basic set of symbols designed to meet these criteria. They have proven to be fast and informative in years of daily use. These symbols are recommended for anyone with a basic understanding of pneumatic control components’ functions, and who seeks to design in a useful and productive manner.
