Seminar on Performance Assessment Techniques

Presented at locations around the world by ExperTune’s Training Partners.
A general process control class. This is not a class on how to use ExperTune.

Class Schedule

#SE-120-2E, Duration: 2 days


In a typical plant, over 75% of assets are tied to control systems. Performance monitoring results in a steady and continuous improvement in the product quality, cost reduction, throughput, and waste reduction in process plants. Tracking the performance, determining plant or unit health becomes essential. Also, directing your resources in the areas of the plant where they are really needed will directly have an impact on the costs. Performance monitoring identifies the areas in your plant where the greatest economic gains are possible.

Who Should Attend:

Anyone concerned with the performance of processes or control loops. Instrumentation technicians, and supervisors, production managers, process, electrical, and project engineers. Management can also appreciate the importance of loop tuning and the new tools available to achieve objectives of today and meet the challenges of tomorrow.

This seminar will allow you to define what are the KPI (key performance indices) for the different areas in your plant. You will learn about most common performance indicators, how to benchmark your process, how to identify process and equipment problems, how to pinpoint operation problems…
