Industrial Process Measurement

Course Content

Aim

To provide an appreciation of measurement systems and calibration techniques.

Pre-requisite

Suited to those personnel who require to be acquainted with the actual work carried out by instrument personnel.

Course Duration

The course is 5 days in duration.

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 PowerPoint Presentation, course notes / hand-outs 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.
