Connection in four-wire configuration

When transducers in a six-wire configuration are con-
nected to amplifiers in a four-wire configuration, the
sense leads of the transducer must be connected to the
corresponding excitation voltage leads: Marking (+) with
(+) and marking (-) with (-), see Fig. 6.1. This measure
also reduces the cable resistance of the excitation volt-
age leads. However, there will be a voltage loss on the
supply leads due to the cable resistance that is still
present and not compensated for by the six-wire configu-
ration. A large part of this loss can be eliminated by a cal-
ibration, however, the temperature-dependent part
remains.
