A. 8 mA
B. 12 mA
C. 16 mA
D. 20 mA
Answer:B
A pressure transmitter has a span of 0-300 psi and a linear output. What is the mA output at 150 psi?
A. 8 mA B. 12 mA C. 16 mA D. 20 mA
Explanation: Since the transmitter has a linear output, we can calculate the mA output using a simple proportion. At 0 psi, the mA output is 4 mA. At 300 psi, the mA output is 20 mA. Therefore, at 150 psi, the mA output is halfway between 4 mA and 20 mA, which is 12 mA.
