This course is a basic introduction for Instrumentation & Process Control that is a section of technology that deals with the science that applies and develops techniques for measuring and controls of equipment and industrial processes. Process control has a broad concept and may be applied to any automated systems such as, a complex robot or to a common process control system as a pneumatic valve controlling the flow of water, oil or steam in a pipe.
This study includes the control manners, in which power fluids act in tanks, pipes, hoses, cylinders and valves, dealing with their electric, pneumatic and hydraulic instruments, no matter if automatic or manual handling. Fluid power is the energy transmitted and controlled by means of a pressurized fluid, either liquid or gas. The term fluid power applies to both hydraulics and pneumatics. Hydraulics (oil or water) use liquids under pressure, while pneumatics use compressed air or other neutral gases.
Industries such as petrochemical, steel, food, paper, and so on, where the instrumentation is responsible for the maximum yield of a process, causing that all energy be transformed into a controlled work. There are many types of instrumentation, as can be seen in the table above. Our main subject is only process control. Thus, the main variables that reflect energy transfers in the process controls are: pressure, level, flow and temperature; called as process variables.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
