According to process control experts, a detailed and specific set of control valve requirements is more than necessary when it comes to good control loop performance. Feb. 21, 2025 Control valve ...

Some wonder if AI will replace PID control loops. The reality is that, instead of replacing PID, AI is stepping in to help keep things running smoothly without upending regulatory trust. Think of AI ...

Spare a moment’s pity for the process engineer, whose job it is to keep industrial automation running no matter what. These poor souls seem to be forever on call, fielding panicked requests to come to ...

Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world that would "make ...

Proportional-integral-derivative (PID) is the most common industrial technology for closed-loop control. A proportional-integral-derivative (PID) controller can be used to control temperature, ...

Current-mode control loops (particularly the popular 4- to 20-mA controls) are used in many industrial applications because of their immunity to induced EMI from motors, contactors, relays, and other ...

The next steps beyond 5G promise great advantages in terms of bandwidth and latency, making possible many new process-control ...

Because the wiring and the inputs and outputs (I/Os) are the most vulnerable elements in a system, be sure to locate and identify these elements in the problem circuit. Sometimes, the only way to test ...

For injection molding — as well as just about every plastic process — process cooling is very important for cycle time and part quality. Cooling sometimes seems like a last-horizon type of variable ...
