Quizplus · Accepted Answer

A final control element directly affects the process variable. A potentiometer, however, is a type of sensor or transducer; it is not used to directly control a process but to measure or adjust electrical resistance within a circuit. Control valves, electro-pneumatic converters, and servomotors are examples of devices that can directly control a process by adjusting flow, pressure, or mechanical movement.
