ELECTRICAL CONNECTION

The following can be connected for measurement signal conditioning:
S
carrier-frequency amplifiers
S
DC amplifiers
designed for strain gauge measurement systems.
The load cells are delivered with a six-wire configuration.

Connection in six-wire configuration

Fig. 5.1 Pin Assignment
With this connector pin assignment, the output voltage at the measuring amplifier is posi­
tive when the transducer is loaded.
5.2

Connection in four-wire configuration

When transducers in a six-wire configuration are connected 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. 5.1. This
measure also reduces the cable resistance of the excitation voltage 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 configuration. A large part of this loss
can be eliminated by a calibration, however, the temperature-dependent part remains.
