Summary of Content

The aim of this course is to provide a detailed foundation in the basic construction and fabrication of sensors and transducer. The focus of this course is in the area of Industrial Instrumentation, specific to sultanate of Oman. Concepts of modern sensors used in Industrial Instrumentation applications are introduced in this course.

Syllabus

The teaching syllabus will cover the following areas: General concepts and terminology: Measurement systems, transducer classification, general input-output configuration, static and dynamic characteristics of a measurement system, Statistical analysis of measurement data. Elastic sensing elements: Diaphragms, bellows, bourdon tubes, beam and column type elements, ring type elements, their construction and design features. Variable resistance transducers: Potentiometers, metal and semiconductor strain gauges and their signal conditioning circuits, strain gauge applications: Load and torque measurement. Inductive transducers: Transformer type, synchros and resolvers, eddy current transducers, electromagnetic sensors, Hall effect sensors, proximity detectors, magnetostrictive transducers and capacitive transducers, tacho generator, stroboscope. Other Transducers: Piezoelectric transducers and their signal conditioning, digital displacement sensors, electro-kinetic transducers, photoelectric transducers, basics of gyroscope, seismic instrument and accelerometers. Semiconductor sensor: Introduction, classification, and basic fabrication techniques.

Learning Outcomes

On completion of this course the student should be able to:1. Summarise the static and dynamic characteristics of a measurement system.(AM1)2. Illustrate the transduction principle of various sensors and transducers used in industry.(AM1)3. Model an Instrumentation system and identify its functionality.(AM5,AM7)4. Recommend appropriate transducers for various measurement system designs (AM5,AM7)5. Suggest suitable compensation techniques for various parameters involved in the measurement process.(AM5,AM7)

Teaching / Learning Strategy

The main teaching method will be based on lectures. The students will be expected to perform directed reading exercises and self-learning exercises on emerging technologies. Tutorials will be used to reinforce the module material discussed during lecture sessions. Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.
