Why 4-20mA SIGNAL IS PREFERRED OVEA A 0-10v signal?
Answer Posted / eid elatawy
L
The resistance R= Resistance const * ---
A
Where L the length of the conductor
and A section area of the conductor
form the above equation we can note that the resistance change
the length of cable so the length of cable affect on signal (V) according to Ohm's Law
V=I*R
so, in case of long distance will affect on the accuracy of the signal.
