Color code of the C2 force transducer connection cable
C2
The C2 is a force transducer that outputs a mV/V signal
based on strain gages. An amplifier is needed to condi­
tion the signal. All DC amplifiers and carrier-frequency
amplifiers designed for SG measurement systems can be
used.
Force transducers are executed in a 6-wire configuration.

The output signal is positive with this pin assignment and
load in the pressure direction. If you need a negative out­
put signal in the pressure direction, exchange the red and
white wires at your amplifier input.
If the force transducer is to be connected to an amplifier
working in a 4-wire configuration, the sense leads must
be short-circuited with the relevant excitation voltage
