Electrical connection
The U9C is a force transducer that outputs a mV/V signal based on strain
gauges. 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
.

Connection to an amplifier
1: White, measurement signal (+)
2: Black, excitation voltage (-)
4: Red, measurement signal (-)
3: Blue, excitation voltage (+)

Pin assignment and color code
The output signal is positive with this pin assignment and load in the pressure
direction. If you need a negative output signal in the pressure direction,
exchange the red and white wires.
The connection cable shielding is connected to the transducer housing. If you
are not using the pre-assembled HBM cable, please connect the cable shield
to the cable socket housing. Use CE standard connectors on the free ends of
the cable to be connected to the amplifier system; the shield must be con
nected extensively. With other connection techniques, a good EMC shield must
be provided in the stranded area, where the shielding must also be extensively
connected.
