Face-to Face

At this meeting we will...

Online

1. First read through any of my "The Big Picture" pages.
2. Next familiarize yourself with the discussion questions so that you can be thinking of them while you read. Note posting deadlines.
3. Then for this mod you want to read and then answer the questions as described.
4. Work on the Your Calculations Corner well before the end of the mod so that you can get feedback from me before the quiz.
5. Take the quiz when you feel like you will do well.
6. Complete assignments before the due dates-remember, the "due" date is not the "do" date.
By the end of this module, you will be able to:

Chapter 8

- Describe process control.
- Explain the function of a control loop.
- Describe the differences between open and closed control loops.
- Identify the components of a control loop.
- Explain signal transmission.

Chapter 9

- Describe the relationship between the measuring instruments (pressure, temperature, level, and flow) and their role in the overall control loop process.
- Describe the purpose and operation of the transmitter in a control loop.
- Discuss differential pressure in relation to the process input to the transmitter.
- Compare and contrast the transmitter input and output signals.
- Describe the function of a current to pneumatic transducer (signal converter).
- Describe the relationship between a 3-psig to 15-psig air signal and a 4mA to 20-mA electric signal.
- Given a process control scheme, explain how a control loop functions.
