Fig. 5.2 Connector pin assignment
With this connector pin assignment, the output voltage at the measuring
amplifier is positive when the transducer is loaded. The plug is implemented in
a 6-wire configuration.
When transducers in a 6-wire configuration are connected to amplifiers in a
4-wire configuration, the sense leads of the transducers must be connected to
the corresponding excitation voltage leads: Marking (+) with (+) and marking (-)
with (-), see Fig. 5.2. 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 6-wire
configuration. A large part of this loss can be eliminated by a calibration,
however, the temperature-dependent part remains. The pin assignment for the
cables available as accessories can be found in data sheet B03643.
