What role does an alarm system play in process control?

It measures temperature variations
It alerts operators to abnormal conditions
It performs data logging
It maintains system pressure

The correct answer is: It alerts operators to abnormal conditions

An alarm system plays a crucial role in process control by alerting operators to abnormal conditions within the system. This function is essential for maintaining safety, efficiency, and reliability in industrial operations. When process parameters deviate from their normal ranges, the alarm system triggers alerts, allowing operators to take timely action to prevent potential hazards, equipment damage, or product quality issues. By providing real-time notifications about the state of the process, the alarm system helps ensure that operators can respond promptly to situations that could lead to serious safety risks or operational disruptions. This proactive approach is vital in maintaining continuous and safe operation within industrial processes.
