The mechanism which changes the value of manipulated variable in response to the output signal from the control unit is called the___________________?
Correct answer: A. Final control element
- A. Final control element
- B. On-off control
- C. Floating control action
- D. None of these
Explanation
The final control element receives the controller output and physically changes the manipulated variable, such as a valve changing fluid flow. On-off and floating control describe control actions rather than the hardware mechanism itself.
