PIDTutor publishes Split-Range Control Book

　　Split-range control uses a single controller with two control valves to maintain a single process variable. It can be used for a variety of applications, such as heating and cooling of a tank or a room. Split-range control is widely used in the process industries, such as pulp and paper, oil and petrochemicals, and mining.

　　George Buckbee, President of PIDTutor, and author of the book, says: "I wrote this book because split-range control is widely used, but is often mis-understood. With split-range control, the devil is in the details. These details and many ‘tricks of the trade’ are included in the book."

　　The book covers all aspects of the use of split-range control. Starting with the basics, the book discusses when to use split-range and when not to, costs and benefits, how to configure the control strategy, how to calibrate the valves, how to tune the loops, and even how to train operators and troubleshoot problems. Color pictures illustrate the key concepts.

　　The book is available on-line via the PIDTutor web site, or via Amazon’s CreateSpace at
