The simplest resistance thermometer configuration uses two
wires. It is only used when high accuracy is not required as
the resistance of the connecting wires is always included
with that of the sensor leading to errors in the signal.
Using this configuration you will be able to use 100 meters
of cable. This applies equally to balanced bridge and fixed
bridge system.
In order to minimize the effects of the lead resistances a
three wire configuration can be used. Using this method the
two leads to the sensor are on adjoining arms, there is a
lead resistance in each arm of the bridge and therefore the
lead resistance is cancelled out.
