Course Content

To provide an appreciation of the operation and application of process plant instrumentation used for the measurement and display of the main process variables of pressure, level, flow and temperature. To also provide an appreciation of the principles of industrial automatic process control and the practical applications of this on plant control.

Suited to those personnel who require to be acquainted with the actual work carried out by instrument personnel and who are involved with instrumentation personnel on a daily basis.

The course will be of ten day's duration.

Optimum Number:
The optimum number of persons on this course will be 8.

Training Aids:
Hands on practicals using purpose build rigs and simulators. Use will be made of lecture notes, PowerPoint presentation and discussion. Delegates will complete practical assignments to ensure they have fully understood but there are no formal assessments or examinations with this course.
