Question 560General Subjects - Assistant Engineer

The correct answer is B) 1250 psig. The reasoning is as follows: In a pneumatic transmission system, the standard industry range for instrument air is typically 3 to 15 psig. With a calibrated scale of 0 to 5000 psig on the pneumatic pressure indicator, the 6 psig transmitted pneumatic signal would correspond to 1250 psig on the indicator's scale, as this value falls within the linear range of the 3 to 15 psig input. The other options are incorrect because they do not accurately represent the relationship between the 6 psig input signal and the calibrated scale of the pressure indicator.
