why 4-20 mA signal is preferred over a 0-10V signal
Answer Posted / supratim samanta
If 0-10 mA is used instead of 4-20mA then there will be
difficulties in error detection.Such as if there is any
fault is the transmission lines..we will never know,wheather
the indicated 0mA current corresponds to the initial
value(calibrated) of the measurement or it is due to fault
in transmission lines.
