Course Content

Aim

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.

Pre-requisite

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.

Course Duration

The course is 10 days in duration; available over 2 consecutive weeks or separate where preferred.

Optimum Number

A maximum of 8 candidates per course.

Course Language

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

Courses can be delivered in other languages however, this would need to be discussed prior to acceptance on the course. It is the responsibility of the person making the booking to make Roxby aware of this requirement.

Training Aids

Using purpose-built rigs and simulators. Use will be made of lecture notes, PowerPoint and discussion. Candidates will complete practical assignments to ensure they have fully understood the concepts delivered.

Assessment

Upon successfully completing, candidates are awarded with A Roxby Training Solutions certificate. Should an accredited option wish to be achieved, an ECITB training certificate can be issued.
