8 Electrical connection
The C11 is a force transducer that outputs a mV/V signal based on strain
gages. An amplifier is needed to condition the signal. All DC amplifiers and
carrier-frequency amplifiers designed for SG measurement systems can be
used.
The force transducers are executed in a four-wire circuit
.

If you need to extend the cable, this should be done using a 6-wire
configuration, so that the cable extension has no influence on the measure­
ment result. The 6-wire circuit regulates the cable resistances, allowing the
measurement system to work independently of the connection cable length and
any variations of measuring lead temperature
.
Only use low-capacitance,
shielded measurement cables as extension cables. A perfect electrical
connection with low contact resistance is essential, and the cable shield must
continue to be extensively connected.
Note that the equipment protection level of your force transducer will decrease
if the cable connection is not tight and water can penetrate the cable.
Transducers with an integrated cable can be irreparably damaged and fail
under these circumstances.
The connection cable shield is connected to the transducer housing.
