Control & Instrumentation Training
The Control & Instrumentation training course covers the practical maintenance aspects of industrial instrumentation with three modules Measurement, Valves and Controllers and is designed to be progressive with each module building on the previous.
Training consists of three training modules normally delivered over 8 days in two blocks of four days or similar combination to suit shift working patterns. The training delivery can be adapted to suit company’s specific requirements in terms of application, hands on practice or specific customer equipment. The training can be on site our Rochester training centre.
This is a highly practical training course focusing on industrial Instrumentation maintenance practices and fault-finding procedures with a lot of the training being hands-on work directly related to the course content.
