Module Title:Process Instrumentation
Language of Instruction:English
Credits: 5
NFQ Level:7
Module Delivered In 4 programme(s)
Teaching & Learning Strategies: Lectures will incorporate a mixture of presentations, examples and student exercises/problem-solving, question and answer sessions, group discussions and online resources. Students will also work collaboratively from time to time in the completion of exercises and development of solutions.
Module Aim: The aim of this module is to enable students to develop an understanding of the principles of operation for a range of industrial measurement instruments (for Pressure, Level and Temperature measurement) and to use this knowledge to usefully consider selection, installation and application issues relating to the measurement systems.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Interpret and apply the terminology and methods used to describe the specification and performance of industrial measurements instruments.
LO2 Explain the principles of operation of the most common instruments used to measure Pressure, Level, Flow and Temperature in industrial applications.
LO3 Implement the equipment and procedural requirements for bench and field calibration of a range of the instruments covered.
LO4 Discuss the relevant process and application parameters to be considered for correct instrument selection and installation.

Module Content & Assessment

Indicative Content
Measurement Terminology
Definition and explanation of terms used for instrument specification and to quantify the quality and reliability of measurements taken. Significance of process variable measurement to the overall production process and the ethics involved in measurement and control.
Pressure Measurement
Pressure Basics; Nature of pressure, types of measurement (absolute, gauge and differential). Measurement Principles; elastic deformation and liquid column. Practical Implementation; manometers, diaphragm, Bourdon tube etc. Pressure Switches and Transmitters (Smart & Dumb). The mA analogue current transmission loop. Installation and application. Precautions and ancillary equipment.
Level Measurement
Level Basics; definitions, nature of level, vessel designs, volume, contents (liquids/solids). Measurement Principles; hydrostatic, capacitance, ultrasonic and radar techniques. Practical Implementation. Level Switches. Installation and application.
Flow Measurement
Flow Basics; definition, type of flow measurement. Measurement principles; differential pressure, velocity, temperature, density. Practical Implementation. Installation and application.
Temperature & Heat Measurement
Temperature Temperature scales. Process issues specific to temperature measurement. Measurement Principles; expansion, bimetallic, resistance change, thermo-voltaic, Practical Implementation; RTDs, thermocouples etc. Thermostats. Installation and application.
Calibration Principles including ethical consideration in instrument data collection, terminology, procedures, precautions, standards, limitations, documentation and scheduling. Solve linear equations to calculate instrument output in units and percentage of range along with percentage error for given process conditions. Individually and as part of a group carry out practical bench calibration on typical industrial pressure, level and temperature measurement instruments and collaboratively develop calibration procedures for wet (field) calibrations.
