Volt drop introduced
on to the common 0 V
line by the supply feed
to the sensor will be
superimposed on to
the signal. The signal
accuracy shift caused
by this is the factor that
limits the cable length.
The potential cable
length is limited by the
permissible volt drop in
the + V and 0 V power
supply feed conductors
to the sensor, that will
ensure an adequate
operating voltage supply
at the sensor.
