Pressure signal to electric signal
Pressure signal to position change
Electric signal to pressure signal
Position change to pressure signal
Answer is Wrong!
Answer is Right!
The correct answer is: B. Pressure signal to position change
A control valve is a device that regulates the flow of a fluid. In pneumatic control systems, the control valve is used as the final control element to convert a pressure signal into a position change. The position change is then used to control the flow of the fluid.
The other options are incorrect because:
- Option A is incorrect because the control valve does not convert a pressure signal into an electric signal.
- Option C is incorrect because the control valve does not convert an electric signal into a pressure signal.
- Option D is incorrect because the control valve does not convert a position change into a pressure signal.
