4 Elect r ical connection
Load cells can be connected either to carrierfrequencyamplifiers or
DCamplifiers.
ATTENTION
Elect r ic and magnetic fields often cause inte r fe r ence voltages that a r e
coupled into the measu r ement ci r cuit.
The r efo r e:
S
only use shielded, low capacity measurement cables
(measurement cables by HBM
1)
meet these requirements).
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 steelsheathed 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 ove r load situation on a single load cell cannot be
detected by means of the output signal.
