Final answer:
The data in process control systems are typically analyzed by computers, not continuously by a person, which makes this option atypical of such systems. Process controls use sensors and negative feedback loops to maintain system variables within normal parameters.
Step-by-step explanation:
All of the following are typical of process control systems EXCEPT: The data are continuously analyzed by a person, who generates feedback. Process control is largely automated, utilizing sensors, computers, and feedback mechanisms to maintain system operation within desired parameters.
The components of a typical process control system include a sensor to monitor values, a control center that compares these values to a set point or normal range, and effectors that are activated to correct any deviation from this range. Negative feedback loops are common in these systems, to reduce excessive responses and thereby maintain variables within normal limits.
Process control systems are used in a variety of technical and engineering contexts, including the regulation of homeostasis in biological systems.
