5 Electrical connection
The following can be connected for measurement signal conditioning:
S
Carrier‐frequency amplifier
S
DC amplifier
designed for strain gage measurement systems.
In the standard version, the transducers come supplied with a 3m cable with a
6‐pin Pancon plug in a six‐wire configuration.

Fig. 5.1 Connection with a 6‐wire cable (choice of 3m or 6m lengths)
With this cable assignment, the output voltage at the amplifier is positive when
the transducer is loaded (
see Fig. 4.1 ).
5.2 Connection with a 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 corresponding excitation voltage leads: (+) with (+) marking and (-) with
