8 Connection
Load cells can be connected either to Carrier‐frequency‐
amplifiers or DC‐amplifiers.
The load cell connection cable should be routed so that
any condensed water or dampness forming on the cable
can drip off. It must not be led to the load cell. In addition,
it must be ensured that no dampness can penetrate the
open end of the cable.

When connecting to amplifiers in 4‐wire technique you must connect the wires blue to green
and black to gray. The following deviations occur with unshortened cables (3 m):
•
sensitivity -0.2 %
•
TKC -0.01 % / 10 K
Notice
Electric and magnetic fields often cause interference volt­
ages to be coupled into the measurement circuit. There­

Only use shielded, low capacity measurement cables
(measurement cables by HBM meet these require­
ments).
