Electrical connection

Load cells can be connected either to carrier‐frequency‐amplifiers or
DC‐amplifiers.
ATTENTION
Electric and magnetic fields often cause interference voltages that are
coupled into the measurement circuit.
Therefore:
S only use shielded, low capacity measurement cables
(measurement cables by HBM
S do not route these measurement cables in parallel to power and control
lines. If this is not possible, protect the measurement cable (e.g. by means
of steel‐sheathed pipes).
S avoid the leakage fields of transformers, motors and contactors.
Load cells can be connected electrically in parallel by connecting up the same
color wire ends of the load cell connection cables. The output signal will then
be the mean value of the individual output signals.
ATTENTION
In such cases, an overload situation on a single load cell cannot be
detected by means of the output signal.

e.g. HBM‐extension cable, 6 wires:
• KAB8/00‐2/2/2 (sold by the meter, order no. 4‐3301.0071 = grey or
4‐3301.0082 = blue)
• CABA1 (cable reel, order no. 1‐CABA1/20 = 20 m or 1‐CABA1/100 = 100
m in length), grey
• CABE2 (cable reel, order no. 1‐CABE2/20 = 20 m or 1‐CABE2/100 =
100 m in length), blue
