4 Mounting instructions
When mounting the load cells, pay attention to the following:
S
Please handle load cells with care!
S
Load cells are precision sensors and so their achievable accuracy depends
greatly on their being mounted correctly!
S
Use suitable hoisting gear for mounting the weighing device!
S
Do not overload load cells even briefly (e.g. due to unevenly distributed
support loads)!
S
When carrying out adjustment work that could endanger the load cells, use
supports (dummies) of equal height!
S
The load must be introduced concentrically to the load application surface
and in the measurement direction of the load cell. Use convex thrust pieces
with sufficiently large radii (HBM accessory).
S
Avoid lateral forces and torques (also see the “Specifications” section)!
S
Depending on the construction, use anti-liftoff devices and limit stops if
necessary!
S
Ensure the force application points of the load cells are all on the same
level. The mounting accessories include shims for this purpose
(
see section 9) !
S
Protect load cells against
- one-sided heat radiation
- the effects of subsequent welding work
1)
- strong temperature variations!
S
To prevent rapid wear, grease the force application part. Please take care
not to use too much grease, as this will cause the rubber ring of the cell to
stick (from maximum capacity >4.7 t)!
1)
Every load cell should be bridged with a twisted copper cable (e.g. EEK... from HBM = approx.
16 mm
2
) during or immediately after installation. This prevents damage due to welding currents.
Grounding the load cell reduces the risk of it sustaining damage due to lightning strikes.
