Introduction to Industrial Automation and Control Course
Introduction:
Globalization has placed increasing demands on modern process control in terms of quality, safety, flexibility, and costs. However, more efficient control can only be achieved through better measurement “when the process instrumentation provides the correct information. The field of process measurement and control is changing at a dramatic rate. Measurements and accuracies that would have been thought of as impossible to achieve are now commonplace.
Course Objectives:
This workshop, PRACTICAL Process Control: Loop Tuning and Analysis, is designed to provide engineers and technicians with the basic theoretical and practical understanding of the process loop and how this can be applied to optimize process control in terms of quality, safety, flexibility, and costs.
On successful completion of this workshop delegates will be able to:
- Understand the major technologies used in the measurement of flow, temperature, pressure, and level
- Review the construction and operation of the most important process instruments
- Evaluate and select the appropriate instrumentation system
- Install process equipment correctly
- Optimize control with effective selection and installation of your process equipment
