Electrical connection

The following can be connected for measurement signal conditioning:
 Carrier‐frequency amplifier
 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.
4.1 Connection with six‐wire configuration
Schematic diagram of a Pancon connector (CE100F26-6), 6‐pin
Fig. 4.1: 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. 3.1).
4.2 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 con­
nected to the corresponding supply leads: Identification (+) with (+) and identi­
fication (-) with (-), see Fig. 4.1. This measure also reduces the cable resist­
ance 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 com­
pensated 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
