This expanded edition explains process variables, setpoints, controller outputs, operating modes, instrument readings, trend interpretation, alarm awareness, and effective field-to-control-room communication.
Featuring original diagrams, fictional control-room scenarios, practical calculations, review questions, and 16 additional applied studies with explained answers and independent exercises.
Developed to strengthen technical understanding and situational awareness in industrial process operations.
