process control. The automated control of a process. Process control is used extensively in oil refining, chemical processing, electrical generation and the food and beverage industries where the creation of a product is based on a continuous series of processes being applied to raw materials.
Keeping this in view, what is the meaning of process control?
Process control is an engineering discipline that deals with architectures, mechanisms and algorithms for maintaining the output of a specific process within a desired range. For instance, the temperature of a chemical reactor may be controlled to maintain a consistent product output.
What is the work of a control engineer?
Control engineers design and oversee the production of many types of complex systems and equipment. The engineer researches, tests, and analyzes the design use in relation to the function of the elements in the system. A control engineer seeks consistent results and operation of a system within specified tolerances.
How does process control work?
To stop any unwanted variation in a production process, a control loop monitors the process regularly to check it's performing as it should. This is usually done by a sensor that measures a particular property like temperature. A transmitter converts the sensor's output into a signal which is sent to a controller.
