2-3. Connecting Loadcells In Parallel
Some industrial applications require several loadcells connected in parallel (e.g., tank or flow scales).
A summing junction box should be used to facilitate connection and corner correction.
2-4. Strain Gauge Sensor Cable Coloration
Cable colors of sensors may differ from one manufacturer to another (it may even differ from one
model to another for some products). Refer to the sensor manual (or data sheet) and check signal names
and colors in order to connect the cables correctly.

‘n’ (number) loadcells connected in
parallel are considered one unit whose
capacity is ‘n’ x rated capacity of
loadcells (loadcells must have the same
capacity, bridge resistance, and mV/V).
The averaging resistor (R) must be in
same relative ratios with a low
temperature coefficient.
Averaging resistors are not needed if
loadcells were designed for parallel
connection.
Notice
When connecting several loadcells in parallel, loadcell capacity should be higher than
expected load to compensate for mechanical shock or eccentric loading.
