A level transmitter using a hydrostatic pressure sensor has a range of 0-1000 inches of water column (inWC) and a 4-20 mA output signal. If the specific gravity of the liquid being measured is 0.8 and the transmitter is currently measuring a hydrostatic pressure of 800 inWC, what is the output signal in mA?
A. 10.42 mA
B. 14.24 mA
C. 16.84 mA
D. 18.45 mA
Answer:B

A. 10.42 mA B. 14.24 mA C. 16.84 mA D. 18.45 mA
Explanation: To calculate the output signal in mA for a level transmitter using a hydrostatic pressure sensor, we need to consider the relationship between the hydrostatic pressure, specific gravity, and the mA output.
