Section B: Course Details

Course Content (As approved by the Academic Council)

Measurement is an essential activity in every branch of Engineering for monitoring, controlling, alarm and safety operation of a plant. It is therefore important, that the study of measurement forms part of courses in further and higher education. Modern measurement systems use highly sophisticated sensors and electronic instruments. To exploit these sensors and instruments, it is essential to understand how the measurements and instrumentation are made. There is a strong emphasis on transducers/sensors (mechanical, electrical and optical types), fundamentals of analogue, electronics and digital instrumentations. This course will also include areas such as, signal conditioning elements, noise elimination techniques, impedance matching, telemetry, data transmission both in time and frequency domain techniques.

Course Objectives

This course covers the basic use and application of sensors, transducers, signal conditioning, telemetering and electronic measuring instruments. The theory of analog DC and AC measuring instruments is first interpreted which is then used to study analog electronic and digital meters. The use and application of different measuring instruments are covered in this course. Different types of sensors and transducer are studied with their analog and digital interfacing for measurement of non-electrical quantities. Basics causes of signal impairment in a measurement device and their mitigation are also introduced in this course. This course also covers the microprocessor-based instrumentation and telemetering system for remote sensing and measurement.
