Course Content

To provide a detailed knowledge of the operation and application of process plant instrumentation used for the transmission of the signals of the main process variables of pressure, level, flow and temperature.


Ideally suited to those personnel who require instrumentation training as part of a multi-discipline engineering programme.

The course is two weeks in duration.

Optimum Number:
Maximum of six delegates per course.

Training Aids:
OHP, information handouts.

The course may be accredited by the way of an NVQ or units towards. If not, a competence based assessment can be applied.
