Introduction to Process Control
COURSE CODE: KCIPRC-02
Credit Value: 2.0
Course Description:
This is a basic course on process control components and how they work. It is designed for entry level control and instrument technicians. Elements of a control loop such as various transmitter types, current-to-pressure (I/P) transducers, actuators, etc., are studied in this course. Learn why some devices fail much more often than others and why some functions are not allowed or are range is limited. Study how measurement, feedback, lead and lag functions work.
Basic function of control systems
control steps, control loops, input and output, signal transfer, transfer medium, types of signals
Basic elements of control loops
sensors, indicators and recorders, fundamentals of process instrumentation, flow transmitters, controllers, final control elements
Transmitters and their function in the control loop
Pneumatic transmitters (standard signal range, operation, calibration, zero adjustment, range adjustment, electronic transmitters (adjusting electronic ‘transmitters, power supply, input
Transducers and converters
I/P and P/I converters, I/I converter
Controllers
Function of controllers (direct- or reverse-acting, considering time, types of control modes)
Control
On-off control, proportional band control, reset or integral mode, derivative or rate mode, tuning
Programmable logic controllers
(Treatment of this topic is only at a high-level in this course)
Final control elements
Function of final control elements
