Open and closed control systems E43
Instruments provide an indication to production staff of status of the plant, such as temperatures, pressures, flows and levels. These signals are normally part of an open loop or closed loop system. This course will explain – the differences between open and closed loop systems and the terms used.
Open and Closed systems
Explains the differences in open loop and closed loop systems.
Describes practical control loops used to measure common process variable for example pressure
Explains the types of lag found in control loops.
This is a foundations subject and if you understand these topics you will be able to apply it to the plant and therefore understand process control. Let’s start this exciting journey which will shape your future”
