Mounting

When mounting the load cells the following points are to be noted:
• Please handle the load cells with care!
• Load cells are precision transducers, the achievable accuracy therefore
depends very much on correct assembly!
• Use suitable lifting gear for mounting the weighing device!
• Do not overload the load cell, not even temporarily (e.g. by unevenly
distributed support loads)!
• Use equal height dummies when carrying out alignment work that may
damage the load cell!
• Ensure point load application in the load cell's direction of measurement.
Use spherical thrust pieces with sufficient radius (HBM accessory).
• Avoid transverse forces and moments (see also the chapter "Technical
Data")!
• Depending on the actual design provide for lift--off protection devices and
limit stops!
• Bring the force introduction points of the load cells to the same level. For
this purpose, the mounting accessories include shims!
• Protect the load cell against
-- one--sided heat radiation
-- influences caused by subsequent welding work
-- major temperature variations!
• In order to prevent fast wear, the force introduction point should be
greased. Please ensure that you do not use too much grease as the cell
butyl ring will otherwise stick from a nominal load >4.7 t!
