Description

In an industrial situation, where it is required to measure and control some aspect of a process, it is often the application of the knowledge and the ingenuity of the Engineer or Technician which is relied upon to solve the measurement and control problem. Therefore, a fundamental understanding of the principle of operation of a range of sensors/transducers and instrumentation techniques applicable in an industrial situation combined with an understanding and  knowledge of Process control techniques and tuning methods, equips the Engineer or Technician with the necessary skills and makes them invaluable in their workplace. 
This course is designed to help students to understand the operating principles and concepts of instrumentation and measurement systems including impedance coupling, intrinsic safety and testing and will enable them to acquire knowledge relating to the characteristics and properties of the variables being measured.
After completing this course, Students will gain an understanding of the Process measurement systems and methods used in a modern instrumentation system.
