Extension Cable; Cable Protection; Emc Protection - HBM RSCC Montageanleitung

RSCC
leads due to the cable resistance that is still present and not compensated for
by the six‐wire configuration. A large part of this loss can be eliminated by a
calibration, however, the temperature‐dependent part remains. The TK
given in the specifications for the transducer therefore does not apply for the
cable and transducer combination when connection is in a four‐wire
configuration, as here the cable percentage must be added.

6.3 Extension cable

The cable of a six‐wire load cell such as the RSCC can be extended with a
cable of the same type.
Only use shielded, low‐capacitance measurement cables for extension.
Ensure that connection is perfect, with a low contact resistance.

6.4 Cable protection

The transducers attain protection class IP68 as per DIN EN 60529. In
applications where the PVC cable of the load cell can be chemically or
mechanically attacked or destroyed, extra cable protection must be provided
by means of standard cable protection systems. The load cell can be fitted
with an adapter with an internal M12 thread (optional "with cable protection
system adapter" version) for mounting the screwed cable gland of the flexible
cable protection tubing. Fit the cable protection system as shown in Fig. 6.2.

O‐ring (provided by customer)
Unscrew the M12 sleeve and replace
with an M12 threaded tube coupling

6.5 EMC protection

Electrical and magnetic fields often induce interference voltages in the
measuring circuit. Therefore:
