Answer:D
How can the presence of bubbles or air pockets in the process line affect the accuracy of a pressure transmitter?
A. Span drift B. Zero drift C. Electrical noise D. Both A and B
Explanation: The presence of bubbles or air pockets in the process line can cause span drift or zero drift in a pressure transmitter, affecting the accuracy of the sensor output signal by shifting the span or full scale of the pressure range or the zero point of the baseline.
