4.3 Shortening the cable

If the transducer is connected to an amplifier with a six‐wire configuration, the
transducer cable can be shortened as required, without adversely affecting
the measurement accuracy.

4.4 Extension cable

Only use shielded, low‐capacitance measurement cables for extension. En-
sure that connection is perfect, with a low contact resistance.
The cable of a six‐wire transducer can be extended with a cable of the same
type.

4.5 Parallel connection (option)

Only load cells with an aligned output (nominal (rated) sensitivity and output
resistance) are suitable for parallel connection. Type PW29 load cells are
available with this option.

4.6 Cable protection

The transducers attain protection class IP68 as per DIN EN 60529 and IP69K,
based on DIN 40050 Part 9 specifications. In applications where the PVC
cable of the load cell can be chemically or mechanically attacked or des-
troyed, extra cable protection must be provided by means of standard cable
protection systems. The load cell is fitted with an adapter with an M12
internal thread, for attaching the screwed cable gland of the flexible cable pro-
tection tubing. Fit the cable protection system as shown in Fig. 4.2.
