Control Systems and Instrumentation notes KNEC Diploma

Introduction:

Engineering control systems are used for the control of physical quantities such as temperature, flow rates, liquid levels, chemical composition, speed of prime movers, position of ships and aircrafts, radar guidance, and machine tool operations.

Control system elements include various physical quantities measuring devices, springs levers, gears, valves, gyroscopes, compressors, accumulators, bellows, motors, resistors, relays, transistors among others. Transducers which convert such quantities into electrical signals are commonly used and the microprocessor is involved in the sophisticated control of medical equipment, engine ignition systems and domestic appliances.

The instructional approach will lay emphasis on demonstration, industrial visits, practical and project work.
