ELECTRICAL CONNECTION
The following can be connected for measurement signal conditioning:
S
Carrier‐frequency amplifier
S
DC amplifier
designed for strain gauge measurement systems.
The transducers are supplied in the standard version with a 3m cable and 6‐pin Pancon
connector in a six‐wire configuration.

Connection with six‐wire configuration

Fig. 5.1
Connection with a 6‐wire cable (choice of lengths: 1.5m, 3 m, 6 m or 12 m)
With this cable assignment, the output voltage at the measuring amplifier is positive
when the transducer is loaded (see Fig. 4.1).
5.2
Connection with four‐wire configuration
When transducers with a six‐wire configuration are connected to amplifiers with a
four‐wire configuration, the sense leads of the transducer must be connected to the cor
responding supply leads: Identification (+) with (+) and identification (-) 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. The TKc value given in the specifications for the transducer therefore does not
apply for the cable and transducer combination when connection is with four‐wire config
uration, the cable percentage must be added.
