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 ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

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, ...

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 ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

Scale-up involves increasing pump sizes, reactor volumes, and flow rates—but the process control logic and system ...

What is the best strategy to get the best rate of change in the PID for a manipulated variable, or is there a more elegant ...

A variety of modules are offered that allow control of temperature, flow, and pressure; the single- and dual-loop temperature modules also provide ramp-and-soak controls. Up to 16 of these modules can ...
