Important
The TC value given in the specifications for the transducer therefore does not apply for
s
the cable and transducer combination when connection is in a four-wire configuration,
where the cable percentage must be added.
The following deviations occur in the case of an uncut cable (3 m):
S
Sensitivity approx. -0.2%
S
TC approx. -0.01% per 10 K.

5.3 Shortening the cable
If the transducer is connected to an amplifier in a six-wire configuration, the transducer
cable can be shortened as required, without adversely affecting the measurement accu­
racy.
5.4 Cable extension
Only use shielded, low-capacitance measurement cables for extending. Ensure that con­
nection is perfect, with a low contact resistance.
The cable of a six-wire transducer can be extended with a cable of the same type.
Cable types recommended by HBM:
S
KAB7.5/00‐2/2/2 (by the meter, Order No. 4‐3301.0071 for gray or 4‐3301.0082 for
blue version)
S
CABA1 (cable roll, Order No. CABA1/20 = 20 m or CABA1/100 = 100 m long)
5.5 Parallel connection
Only load cells with an aligned output (nominal (rated) sensitivity and output resistance)
are suitable for parallel connection. The load cells can be wired in parallel by joining the
load cell cable core ends of the same color. The type VKK terminal boxes or the VKK2R-8
Ex version for potentially explosive areas are available in the HBM product line for this
purpose. The output signal is then the average of the individual output signals.
Important
Overloading in an individual load cell cannot then be detected from the output signal after
load cells have been connected in parallel.
