A pressure transmitter has a range of 0-1000 psi and a linear output. What is the mA output at a pressure of 400 psi if the transmitter has a span of 20 mA?
A. 8.3 mA
B. 11.2 mA
C. 10.4 mA
D. 14.6 mA
Answer:C

A. 8.3 mA B. 11.2 mA C. 10.4 mA D. 14.6 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 (1000 psi in this case).
