150

Answer / am

12 mA is 50% of the signal range (4 to 20 mA).
Here, transmitter range is -200 to 500 mmWC. That means its span is 700 mmWC. So, 50 % of the range will be 350, which we have to add to the lower range. That is 350+ (-200) = 150 mmWC.

Answer / suresh agravat

-200 to 500(urv-lrv)/span
700span
-200=4mA
-25=8mA
150=12mA
325=16mA
500=20mA

Answer / muhammed shafeeq

sry
pls add formula

Answer / rampal.m.

-200 for 4ma and 500 for 20ma so span 16ma for span 700 that why
16ma for 700
1ma for 700/16 so 12ma for 700/16 and multiply by12ma=525
this -200+525=325
ans is for 12ma
=325mmwc
