Q19. Final control elements are used to A. Measure process variables. B. Manipulate process variables. C. Generate control Signals. D. Convert control signals into appropriate action. Q20. Which of the following is not a final control element? A. Dampers B. Pneumatic actuator C. Potentiometer D. Solenoid valve Q21. A current to pressure transducer (I/P) with a range of (4-22 mA to drive 2- 16 psi), is used to drive a pneumatic system to control a valve. If the pressure read back from the P/I converter is 9 psi, what is % of the opening of the gate?

Step 1

This can be calculated using the formula: \[ \% \text{ of current signal} = \frac{\text{Current signal} - \text{Minimum current signal}}{\text{Maximum current signal} - \text{Minimum current signal}} \times 100 \] where the minimum current signal is 4 mA and the Show more…
