To provide the participants with a better understanding of the control instrument and the problems related to their use.

At completion of the course, the participants:

• Know the main types of instruments and their working principle.
• Understand the working principle of the different types of control loops.
• Know the typical DCS architecture and the typical Safety System layout.
• Specify and design instrumentation systems for pressure, level, temperature and flow.
• Correctly select and size control valves for any particular application.
• Troubleshoot and identify problems with instrumentation systems.
• Isolate control loops and identify a faulty instrument.

All those working on process plants who are familiar with the general purpose of process measuring instruments and control equipment. This will include process operators and trainee instrument technicians and engineers on all types of oil, gas and chemical plants. This short intensive course is aimed at operators, technicians and engineers who are currently employed in these industries and require further information on the equipment that they will use.

This interactive Training will be highly interactive, with opportunities to advance your opinions and ideas and will include;

• Lectures
• Workshop & Work Presentation
• Case Studies and Practical Exercise
• Videos and General Discussions
