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 and output)

Transducers and converters

I/P and P/I converters, I/I converter


Function of controllers (direct- or reverse-acting, considering time, types of control modes)

Control modes

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


Diaphragm design, adding a valve positioner, hydraulic piston actuators, motor actuators

Performance characteristics

Other final control elements

Single element control loops, cascade control, feed-forward control, ratio control
