A level transmitter using a displacement-type sensor has a range of 0-50 inches and a 4-20 mA output signal. If the transmitter is currently measuring a displacement of 30 inches, what is the output signal in mA?
A. 8.6 mA
B. 12.6 mA
C. 13.6 mA
D. 20.6 mA
Answer:C
A level transmitter using a displacement-type sensor has a range of 0-50 inches and a 4-20 mA output signal. If the transmitter is currently measuring a displacement of 30 inches, what is the output signal in mA?
A. 8.6 mA B. 12.6 mA C. 13.6 mA D. 20.6 mA
Explanation: In the scenario of a 4-20 mA current loop system, the minimum value of the process (0 inches for this level transmitter) is represented by 4 mA, while the maximum value (50 inches in this case) is denoted by 20 mA.
