A temperature transmitter has a range of 0-220°C. What is the mA output at a temperature of 85.6°C if the transmitter has a span of 20 mA?
A. 10.22 mA
B. 11.82 mA
C. 12.12 mA
D. 17.07 mA
Answer:A

A. 10.22 mA B. 11.82 mA C. 12.12 mA D. 17.07 mA
Explanation: In a 4-20 mA current loop standard, 4 mA corresponds to the minimum process value (0°C in this case), and 20 mA corresponds to the maximum process value (220°C in this case).
