Question

A temperature control system is known as:
1. Process control system
2. Servomechanism
3. Cascade control system
4. None of these

Answer 1

Correct Answer - Option 1 : Process control system

 Tempurature Control System:

• A temperature controller is a device that is used to control temperature. It does this by first measuring the temperature (process variable),
• It then compares it to the desired value (set value).
• The difference between these values is known as the error (Deviation).
• Temperature controllers use this error to decide how much heating or cooling is required to bring the process temperature back to the desired value.
• Once this calculation is complete the controller will produce an output signal that affects the change required.
• This output signal is known as the (manipulated value) and is normally connected to a heater, control valve, fan, or some of the "final control element" which actually injects or removes heat from the process.
• Thus temperature control system is known as a Process control system.
