Summary of Content

This module explains different types of process control loops, its functions, operational models and serves to gain knowledge on measurement and instrumentation sensors. It also covers the techniques of communicating the measured results throughout a process plant.

Syllabus

Introduction to process control and instrumentation: Process control principles, block diagram presentation, piping and instrumentation diagram, analogue and digital processing, transducer specifications and sensor time response. Controller Principles: Process characteristics, control parameters, two position control mode, multi-position mode, floating control mode, continuous controller modes, PI, PD and PID controller modes. Control Loop Characteristics: Control system configurations, analogue control, supervisory and digital control, loop disturbance, stability criterion and process loop tuning. Pressure Measurement: Types of pressure measurement, dynamic pressure systems, manometers, mechanical pressure measurements, electrical pressure sensors. Flow measurement: Revisions of flow terms and concepts, orifice plate and venturi meter, vertex shedding, coriolis, electromagnetic, ultrasonic and laser sensors. Level measurement: Single point: mechanical switches (float and pressure), vibration damping, rotating paddles, proximity sensors, radiation absorption. Continuous: mechanical ranging, buoyancy, hydrostatic, ultrasonic ranging, capacitance probes, radio wave ranging. Temperature measurement: Thermocouple, resistance thermometers, thermistors. Radioactive techniques: Basic concepts. Optical, infra-red.

Learning Outcomes

On completion of this module the students should be able to:1. Evaluate the system responses to different inputs. (AM1)2.

Teaching / Learning Strategy

The main teaching method will be based on lectures. The student will be expected to perform directed reading exercise and self-learning exercises on emerging technologies. Tutorials will be used to reinforce the module material and to discuss the issues raised by the directed reading.
