4. Transport, packaging and storage
4. Transport, packaging and storage
4.1 Transport
Check the shear beam for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during internal
transport, proceed carefully and observe the symbols on the packaging.
▶
With internal transport, observe the instructions in chapter 4.2
“Packaging and storage”.
As precision measuring instruments, transducers require careful handling during
transport and mounting. Load impacts during transport (e.g. hitting a hard surface) can
lead to permanent damage, resulting in measuring errors in the subsequent measuring
operation.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change
in installation site, sending for repair).
The measuring spring is made completely of stainless steel.The version of the acces-
sory cables has an ingress protection of IP67.The ingress protection of IP67 is only
guaranteed with the cable connected. During storage the protective cap must always be
on the electrical connection to avoid entry of moisture and dirt.
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +85 °C
■
Humidity: 35 ... 85 % relative humidity (non-condensing)
Avoid exposure to the following factors:
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Dust, dirt, and other objects may not be deposited in such a way that they form a
force shunt with the measuring spring, since this will falsify the measuring signal.

5.1 Mounting precaution
■
Shear beams are sensitive measuring instruments and must be handled with appropriate
care.
■
Before installing the shear beam, check whether the mounting position have been
executed dimensionally accurately, thus guaranteeing problem-free mechanical
fixation of the shear 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 shear beam.
■
In the area of the contact surface of the shear 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 improper loads on the shear beam due to torsional
and shear forces.These loads cause measured errors and can permanently damage
or destroy the shear beam.
■
Incorrect loading can lead to permanent damage resulting in a zero point offset in the
unloaded state.
■
Carry out the mounting of the shear beam without using strong force (e.g. hammer).
■
Do not use the shear beam as a climbing aid.
■
The force acting on the shear 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 shear 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 shear beam may only be subjected to loads in the type of bearing provided.
