Page 10: Load Cell Dummies
Revision 11/12 General Conditions for Installation and Assembly Load Cell Dummies Load cells are sensitive sensors. To protect them from damage, they should only be handled as late as possible for installation and transport. During installation and transport, these should be replaced by dummies or phantoms. Dummies can be constructed as follows for example: 1. -
Page 11: Welding And Installation Work
Revision 11/12 General Conditions for Installation and Assembly Loads must be introduced precisely in the direction of measurement of the load cells. Torsion and bending moments, off-center loading and transverse loads are disturbance forces that lead to incorrect measurements and can cause damage if exceeding the permitted limitations of the load cells and mounting elements. -

Revision 11/12 Elastomer bearing Assembly The conditions for installation are very different. The load platform can be very low or relatively high. It could be a container, a platform or a conveyor for example. The following assembly instructions can only be taken as general guidelines. WARNING Proper tools are to be used for lifting the load platform. - Page 17 Revision 11/12 Elastomer bearing Bolt the elastomer bearing (10) to the load cell (3) with the hexagon bolt (8) and the washer (9). Hold the elastomer bearing (10) down when tightening the hexagon bolt (8) to prevent damage being done to the load cell. The arrow on the front of the load cell indicates the direction of measurement.
