why 4-20 mA in covection system?

Answer Posted / jazz

4-20 mA signal differentiates live process 0% with 4mA
signal with a wire break (0 mA), current is also used for
transmission because even if your receiver or PLC/DCS card
is far away current signal sent proportionately by the
transmitter will be received as the same current at the
receiver/PLC/DCS card, although it is converted as a voltage
signal (1 to 5 VDC) by a 250ohm resistor, since
micro-processor process signals in voltage levels.
