3.1 Application
3.1.1 Use of compact installation units
The compact installation unit handles the introduction of force into the load cells by means of
a pendulum support.
This pendulum support has the following effect:
● The weight force is introduced centrally into the load cell.
● The load cell is decoupled from the load bearing implement, e.g. of a container. The load
bearing implement can expand, e.g. as a result of changes in temperature, without
tensioning the load cell.
● The load bearing implement remains in the center in the event of thermal expansion.
● Following a lateral displacement, the load bearing implement returns to its rest position as
soon as the transverse force is no longer active.
The compact installation unit allows simple and exact installation of the load cell:
● It is not necessary to strip down the compact installation unit.
● It is not necessary to remove the compact installation unit.
● The compact installation unit can be used as dummy.
● The top plate is secured by means of two countersunk head screws.
● As a result of the two countersunk head screws, the position of the top plate with regard
to the base plate is adjusted ideally.
● The load cell can be inserted before or after installation of the compact installation unit.
● The load cell is protected during installation work.
● The load bearing implement can be lowered safely and controlled onto the load cell.
The compact installation units have the following characteristics:
● Easy installation of the load cell
● Easy adjustment of the load cell under the load bearing implement
● Self-centering on the load bearing implement
● Can be used as a dummy for light installation work
● Safe and controlled lowering of the load bearing implement
● Can be used as a transport lock by fixing the top plate
● Integrated lifting protection
