OK, so here’s a shameless plug for my short book “Mastering Split-Range Control”. It’s 30 pages, with everything you could ever want to know about Split-Range Control. Available via Amazon CreateSpace at: https://www.createspace.com/3395995 .

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.

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.
