How can atmospheric pressure affect the accuracy of a pressure transmitter?
A. Zero drift
B. Span drift
C. Both A and B
D. None of the above
Answer:A
How can atmospheric pressure affect the accuracy of a pressure transmitter?
A. Zero drift B. Span drift C. Both A and B D. None of the above
Explanation: Atmospheric pressure changes can cause zero drift in a pressure transmitter, affecting the accuracy of the sensor output signal by shifting the zero point of the pressure range.
