In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

I recently surveyed the on-site development of the control system for a large concentrated solar power station. This “first of a kind” facility offered many control challenges, such as balancing heat ...

If you have a process that needs to be performed -- but with variations -- then implementing the Template Method pattern will give you simpler, more extensible code. You’ll also recognize this pattern ...

The CS Series of process-control modules provides PID loop control of any process without using a PLC. Modules offer control of temperature, flow, and pressure. Single and dualloop temperature modules ...
