Measurements and Sensor Technology

This module introduces the basic fundamental of measurement and sensor technology. It covers from characteristics of measurement, SI standard to different types of sensors used in measurement systems such as displacement, level, velocity, flow and temperature. Principles of modern sensor technology and measurement devices are introduced. A summarized review or introduction to the electrical circuit is also covered for the background knowledge of electrical sensors. At the end of the module, students are to implement and practice the knowledge learned and to evaluate and understand measurement tool or system with sensor technology.

The topics covered in this module include:

• To describe and understand the fundamentals and fundamentals and process of measurement and interpret related standards
• To evaluate static characteristics of measurement and determine its accuracy, precision, reproducibility, repeatability, hysteresis and nonlinearity; and analyse the causes of errors
• To explain the principle of sensors and transducers, determine and evaluate the sensitivity of sensors, and explain and deal with non-linearity of some sensors
• To comprehend and apply sensor technology in spatial measurements such as proximity, displacement, distance, range, pressure, temperature, flow and level and explain the principle of their measurement.
