Process Control refers to the methods and technologies used to manage and regulate industrial processes. It ensures that the output of a process remains consistent and meets desired specifications. By monitoring variables such as temperature, pressure, and flow rate, process control systems can make real-time adjustments to maintain optimal performance. These systems often utilize sensors and controllers to gather data and execute commands. For example, a temperature sensor might detect a rise in heat and signal a controller to activate a cooling system. This automated feedback loop helps improve efficiency, safety, and product quality in various industries, including manufacturing and chemical processing.
