ISA releases pocket tuning guide
This portable summary of all the practical considerations for tuning loops has been written specifically for practicing instrument, process control, and process engineers. It includes step-by-step descriptions of the three best field-proven tuning procedures, a table of typical tuning settings, a summary of valve performance problems, logic diagrams for troubleshooting, and over 70 useful "rules of thumb."
Even more advanced than the first edition, the second edition includes a new section on methods for reducing valve backlash and sticktion and preventing excessive sensor lag and noise. The new chapters also include adaptive control and the application recommendations and considerations for batch control, boilers, crystallizers, columns, dryers, evaporators, extruders, neutralizers, reactors, and several other types of process equipment.
