With a dose of humor to sweeten a serious message, noted control systems author Greg McMillan offers an experienced-based guide to what can so often go wrong with the systems that measure, regulate, and control industrial processes-from pH measurements to temperature and pressure monitors to process interlock problems. Using anecdotes, dialogue and dramatized skits, the book helps make more vivid the abstract concepts of how control systems actually do-or don't-work in real industrial settings.
