PCT 111 - Process Control I
This course is designed to provide operators/technicians with an introduction to the basic operating principles of process control systems. Topics of study will include control principles, the elements of process control systems, and process control signals and systems. The course also provides for an introductory study of various input and output devices used to control process variables in the petroleum, petrochemical, chemical, pharmaceutical, and food processing industries. Primary emphasis will be placed on processes that require the measurement of pressure, level, flow, and temperature.
Upon successful completion of this course, students should be able to:
List the basic principles, characteristics and applications of process control systems.
Describe the various methods used to implement process control systems.
Explain the methods used to generate process control signals.
Define the basic concepts concerning transducers, as well as investigate the different types of output devices and signals used to control processes.
Describe the nature of fluids as well as the causes and effects of hydrostatic and dynamic pressure.
Describe fluid flow, characteristics of pressure, and pressure head, in regard to process control parameters.
Describe the instruments, methods and principles of operation used to measure pressure, level, and flow in fluids.
Determine the various operating conditions of pressure switches.
Relate the concepts of heat exchange.
Describe the physical changes heat produces in matter.
Determine the major differences between AC and DC motor operation, the fundamental methods of controlling each, and some of the problems associated with each type.
Explain closed loop control system theory relating to the purpose of closed loop control and the different modes of controller operation.
Discuss some of the more advanced aspects of automatic controllers, with relevance to safety and alarming of controllers.
Identify the real time limitations and implications and process characteristics required to transmit serial information between MTU and RTUs with regard to the limiting factors of a real time SCADA system.
Explain the primary purpose of process control and identify the four main processes variables associated with process control regulations.
