The C9C 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

Cable shield, connected to the housing
Fig. 7.1 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, swap the red and
white wires.
The connection cable shield 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
