Electrical Connection; Connection To An Amplifier - HBM U2B serie Montageanleitung

Electrical connection

7 Electrical connection
The U2B 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 car­
rier-frequency amplifiers designed for SG measurement systems can be used.
Force transducers are executed in a 6-wire configuration.

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,
exchange the red and white wires.
The connection cable shield is connected to the transducer housing. If you are
not using pre-wired HBM cables, 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 connected exten­
sively. With other connection techniques, a good EMC shield must be provided
in the stranded area, where the shielding must also be extensively connected.
