Two key components of an automated process control system are the set point and the comparator. The set point device establishes a value for the desired state. The comparator device calculates how far the process is from this value.
LEARNING OBJECTIVES- List examples of set point devices
- Define an op-amp device
- List the functions that a comparator performs on feedback and input signals
- Understand how an error signal is produced in a differential amplifier
- Define gain
