________________________________ _
4-20mA Current Conversion Options.
The primary reason for for using 4-20mA currents in the
transmission of analogue signals is because currents can be sent
a long way without loss and without being greatly degraded by
noise. When voltages are being transmitted over anything but
very short lengths the resistance in the cables leads to a drop in
the received signal, some voltage is dropped across the cable
itself. However, due to the law of conservation of current,
currents can be transmitted without loss.
