5.1 Mounting precaution
■
Bending beams are sensitive measuring instruments and must be handled with appro-
priate care.
■
Before installing the bending beam, check whether the mounting position has been
executed dimensionally accurately, thus guaranteeing problem-free mechanical
fixation of the bending beam.
■
It must be ensured that there is no force shunt between the contact surface of the
transducer and the force introduction. The measuring spring must also be free of
force shunts in the area of the force introduction under rated load. A gap of at least
0.5 mm must be provided.
■
Before installation, make sure that the drilling chips have been removed from the
holes.
■
Depending on the installation situation, lubricant may be required in the holes for
mounting the bending beam.
■
In the area of the contact surface of the bending beam, an even surface must be
ensured.
■
Depending on the installation situation and the availability of mechanical mounting
kits, holes must be drilled.
5.2 Mounting instructions
CAUTION!
Damage to the instrument through improper installation
■
Improper assembly can lead to incorrect loads on the bending beam due to torsional
and transverse forces. These loads cause measuring errors and can permanently
damage or destroy the bending beam.
■
Incorrect loading can lead to permanent damage resulting in a zero point offset in the
unloaded state.
■
Carry out the mounting of the bending beam without using strong force (e.g.
hammer).
■
Do not use the bending beam as a climbing aid.
■
The force acting on the bending beam must be applied at the designated point in the
correct load direction.
■
Pay attention to the mounting instructions.
■
The output signal and the pin assignment are stated on the product label.
■
During mounting of the bending beam, the output signal (force value) must always be
monitored to avoid mechanical overload.
■
Avoid torsional torques, off-centre loads and transverse loads or lateral forces. Trans-
verse loads and lateral forces also include the corresponding components of the
measurands that are introduced slanted.
■
The bending beam may only be subjected to loads in the type of bearing provided.
