Summary of Content

The module provides an overview of the measurement system model which includes the pathways of both wanted and unwanted signals, together with sources of error. Techniques to reduce these unwanted effects are discussed. Signal conditioning techniques are developed for a range of commonly used industrial sensor types and the signal is considered in both time and frequency domains. Protocols for the digital transmission of measurement data are introduced. Finally some advanced sensing modalities, such as fibre optics and thermal imaging, are discussed and contextualised.

Learning Outcomes

Upon successful completion of this module, students should be able to:1. Identify the elements of a measurement system2. Analyse a real measurement system in terms of the general model3. Apply error reduction techniques to improve the performance of a measurement system4. Design appropriate signal conditioning systems for a range of sensors to achieve goals such as linearization and S/N improvement5. Identify and describe the features of common signal transmission protocols6. Understand the operation and application of vibration transducers7. Understand the operation and application of OFS and thermal sensors

Teaching / Learning Strategy

The module is tutorial-based with a significant element of self-study. Lectures will be used to introduce topics with worked examples and provide guidance on what to study. Deeper understanding will be attained through individual completion of tutorial questions provided by the lecturer and work based case studies. Support will be provided in tutorial and laboratory sessions in which tutors will be available to clarify concepts and resolve difficulties.
