A pressure transmitter has a range of 0-150 psi and a linear output. What is the mA output at a pressure of 140 psi if the transmitter has a span of 20 mA?
A. 15.93 mA
B. 16.93 mA
C. 17.93 mA
D. 18.93 mA
Answer:D

A. 15.93 mA B. 16.93 mA C. 17.93 mA D. 18.93 mA
Explanation: In a 4-20 mA current loop standard, 4 mA corresponds to the minimum process value (0 psi in this case), and 20 mA corresponds to the maximum process value (150 psi in this case).
