D. often used for chiller or boiler pressure control



Answer :

Final answer:

General-purpose controllers play a crucial role in industrial processes by regulating parameters like temperature, composition, and flow rates.


Explanation:

General-purpose controllers are versatile devices commonly utilized in industrial applications to control various processes. These controllers, such as PID controllers (proportional, integral, derivative), are essential in maintaining desired outcomes by adjusting parameters like temperature, composition, and flow rates. They can be installed by equipment manufacturers and are often used for specific tasks like chiller or boiler pressure control.
