This section describes how to connect one or more load
cells.
You can connect a maximum of 16 SG load cells in a full
bridge circuit with a bridge resistance of 350 Ω each.
Transducer excitation is implemented in the basic device
WE2111 with 5 V
We recommend connecting the load cells via a suitable
junction if several load cells are connected, e.g. the HBM
model VKK2-8.
Important
Not all load cells can be connected in parallel. Refer to
the operating manual of the load cells to see if this is
possible.
For EMC reasons, a double shielded cable is
advantageous for connecting the load cell(s), e.g. HBM
model 4-3301.0071 with 3 ∗ 2 ∗ 0.14 m
