Answer / praful

Mostly instruments are designed for 24v supply and 4to 20ma
output here we have 12v supply so resistance should be 125
ohms so we can make 550 ohms into 125 ohms by connecting
161ohms resistance in parallel for that we require 323mtr
cable.so we can use almost 300mtr cable. this is just my
practical assumption and i dont have any theoretical proof
for the same.

Answer / c heman

Assume it is a 4-20 ma tx. 20ma*550= 11volts. minimum
supply is required. so allowable voltage drop is only 1
volt.
so max. 100meter u can use.

got the answer, don,t foget to say thanks.
