Brief description

Measurement is an essential part of the scientific process. Instrumentation is the technology of measurement. In this module, students are taught the fundamental principles of instrumentation, to design a measurement system which takes due regard of problems such as accuracy, time response and noise of the overall system and its suitability for a particular measurement.
Modern instrumentation and data acquisition systems are invariably computer controlled, this module reflects this in its use of PC and other programmable devices to control and acquire data from sensors of various types.


What is an electronic instrumentation system? A top-down approach to system design.
Types of signal encountered by instrumentation systems.
Important terms associated with instrumentation systems.
Comparison of digital and analogue signals.
Analogue to digital conversion and vice versa - sampling and quantisation.
Types of converters and the limitations associated with them.
Physical origins of fundamental noise and its effect on instrumentation.
Examples of sensors used in instrumentation systems.
Effects of loading.
Review of AC circuits and detailed analysis of simple RC circuit.
Use of programmable systems for instrumentation.
Interfacing instrumentation systems
