Industrial Process Control

Course Content

Aim

To provide a detailed knowledge and understanding of the principles of industrial automatic control and the practical application of these on process plant control systems.

Pre-requisite

Suited to those personnel who may require training towards multi-discipline engineering and who are required to perform an instrumentation role on return to their workplace.

Course Duration

The course is 10 days in duration.

Optimum Number

The optimum number of candidates is 8 per course.

Course Language

The course is delivered in English. Therefore candidates must have a good standard of both written and verbal English.
