Raising the Curtain on STEM Education

STEM education is becoming more important in today’s fast-paced technical world. But some kids may have a difficult time with traditional STEM classes especially when a student doesn’t think they’re a “math or science type.” One way to encourage an awareness of STEM (Science, Technology, Engineering, Math) is to look for activities that already attract…

A Quick View of SCADA in Oil and Gas

For quick and secure access to production and process data, a PC-based supervisory control and data acquisition (SCADA) system is often the best solution. Whether upstream, midstream or downstream in the process, data can be collected by the SCADA system using a variety of built-in tools. Once collected from controllers and smart devices, the data…

Pneumatic Circuit Symbols Explained

Directional air control valves are the building blocks of pneumatic control. Pneumatic circuit symbols representing these valves provide detailed information about the valve they represent. Symbols show the methods of actuation, the number of positions, the flow paths and the number of ports. Here is a brief breakdown of how to read a symbol.

Understanding Pneumatic Air Preparation

A steady supply of clean and dry air is required to protect all the pneumatic components in machines, equipment and processes and to ensure their proper operation. While controlling mechanical motion with pneumatics—such as clamping, positioning, pushing and lifting—is often the focus, clean and dry air with enough flow to provide the required pressure must…
