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 ...

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 ...

Power plants–especially coal-fired boilers–pose a set of process control problems unparalleled in other industries. Rapid load ramps, continuous unit demand changes, variable fuel quality and process ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...

Nominal pressure rating is 5,076 psi and peak rating is 5,801 psi. The control system includes a high-pressure A4VSO axial-piston pump with swashplate design, a proportional valve with valve ...

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 ...
