Process control systems are essential in managing and regulating industrial processes. They use various sensors and controllers to monitor conditions such as temperature, pressure, and flow rates. By adjusting these parameters automatically, these systems ensure that processes operate efficiently and safely, minimizing waste and maximizing productivity. These systems can be found in various industries, including manufacturing, chemical processing, and oil refining. They often employ feedback loops to continuously assess performance and make necessary adjustments. This helps maintain optimal operating conditions, ensuring that products meet quality standards while reducing the risk of accidents or equipment failures.
