1 Safety Instructions
Intended use
The type series K-LK1/600N-WH special force trans
ducers are solely designed for measuring static and dy
namic tensile and compressive forces within the load lim
its specified by the technical data for the respective
maximum load capacities. Any other use is not appropri
ate.
To ensure safe operation, it is essential to comply with
the regulations in the mounting instructions, the safety
requirements listed below, and the data specified in the
technical data sheets. It is also essential to observe the
applicable legal and safety regulations for the relevant
application.
The force transducers are not intended for use as safety
components. Please also refer to the "Additional safety
precautions" section.
Proper and safe operation of force transducers requires
proper transportation, correct storage, setup and mount
ing, and careful operation.
Load carrying capacity limits
The information in the technical data sheets must be
complied with when using force transducers. The re
spective specified maximum loads in particular must
never be exceeded. The following limits set out in the
technical data sheets must not be exceeded:
SLimit forces
SLateral limit forces
SBreaking forces
SPermissible dynamic loads

STemperature limits
SLimits of electrical loading capacity
Please note that when several force transducers are in
terconnected, the load/force distribution is not always
uniform.
Use as a machine element
Force transducers can be used as machine elements.
When used in this manner, it must be noted that, to favor
greater sensitivity, the force transducers were not de
signed with the safety factors usual in mechanical engin
eering. Please refer here to the technical data and load
ing capacity limits.
Accident prevention
The prevailing accident prevention regulations stipulated
by the Employer's Liability Insurance Associations must
be taken into account, even though the nominal (rated)
force values in the destructive range are well in excess of
the full scale value.
Additional safety precautions
Force transducers cannot (as passive transducers) im
plement any safety-relevant cutoffs. This requires addi
tional components and constructive measures, for which
the installer and operator of the plant is responsible.
In cases where a breakage or malfunction of the force
transducer would cause injury to persons or damage to
property, the user must take appropriate additional safety
measures that meet at least the requirements of applic
able safety and accident prevention regulations (e.g.
automatic emergency shutdown, overload protection,
catch straps or chains, or other fall protection).

Safety Instructions
K-LK1/600N-WH A4303-1.0 HBM: public 5
The electronic system that processes the measurement
signal must be designed in such a way that
no secondary damage occurs if the measurement signal
fails.
General dangers of failing to follow the safety
instructions
Force transducers are state-of-the-art and reliable. There
may be dangers involved if the transducers are mounted,
set up, installed and operated inappropriately, or by un
trained personnel. Every person involved with setting up,
starting-up, operating or repairing a force transducer
must have read and understood the mounting instruc
tions and in particular the technical safety instructions.
The force transducers can be damaged or destroyed by
non-designated use of the force transducer or by non-
compliance with the mounting and operating instructions,
these safety instructions or any other applicable safety
regulations (BG safety and accident prevention regula
tions) when using the force transducers. Force trans
ducers can break, particularly if overloaded. The break
age of a force transducer can also cause damage to
property or injury to persons in the vicinity of the force
transducer.
If force transducers are not used according to their desig
nated use, or if the safety instructions or specifications in
the mounting and operating instructions are ignored, it is
also possible that the force transducer may fail or mal
function resulting in the injury of persons or damage of
property (due to the loads acting on or being monitored
by the force transducer).
The scope of supply and performance of the transducer
covers only a small area of the force measurement tech
nology, as measurements with (resistive) strain gage
sensors presuppose the use of electronic signal pro

cessing. In addition, equipment planners, installers and
operators should plan, implement and respond to the
safety engineering considerations of force measurement
technology in such a way as to minimize residual
dangers. Pertinent national and local regulations must be
complied with.
Conversions and modifications
The design or safety engineering of the transducer must
not be modified without our express permission. Any
modification shall exclude all liability on our part for any
damage resulting therefrom.
Maintenance
The special force transducers K-LK1/600N-WH are main
tenance-free.
Disposal
In accordance with national and local environmental pro
tection, material recovery and recycling regulations, old
transducers that can no longer be used must be dis
posed of separately and not with normal household
waste.
If you need more information about disposal, please con
tact your local authorities or the dealer from whom you
purchased the product.

3 Application area and operating instructions
The K-LK1/600N-WH type series force transducers are
suitable for measuring tensile and compressive forces.
They provide highly accurate static and dynamic force
measurements and must therefore be handled very care
fully. Particular care must be taken during transport and
installation of the devices. Dropping or knocking the
transducer may cause permanent damage.
The force transducers are made of stainless steel. They
are maintenance-free and can even be installed in diffi
cult to access areas. Their measurement signals can be
transmitted to distant test control points. It is essential to
provide careful sealing so that sensitive strain gage ap
plications are protected by the housing.
The technical data specifies the permissible limits for
mechanical, thermal and electrical stress. It is essential
that these are taken into account when planning the
measuring set-up, during installation and, ultimately, dur
ing operation.

Conditions on site
10 A4303-1.0 HBM: public K-LK1/600N-WH
4 Conditions on site
Protect the transducer from weather conditions such as
rain, snow, ice, and salt water.
Ambient temperature
The temperature effects on the zero signal and on the
sensitivity are compensated.
The nominal temperature range must be maintained to
obtain optimum measurement results.
The arrangement of the SG results in high insensitivity
to temperature gradients due to the construction. Never
theless, constant or very slowly changing temperatures
are best. A radiation shield and all-round thermal insula
tion produce noticeable improvements, but must not be
allowed to set up a force shunt.
Moisture and corrosion protection
The force transducers are not hermetically sealed and
must be protected against permanent moisture. The
transducers attain protection class IP54 as per
DIN EN 60259.
The force transducers must be protected against chemic
als that could attack the steel or aluminum.
On stainless steel force transducers, it must be noted
that acids and all materials which release ions will also
attack stainless steels and their welded seams. Any res
ulting corrosion could cause the force transducer to fail.
In this case, appropriate protective measures must be
implemented.

Conditions on site
K-LK1/600N-WH A4303-1.0 HBM: public 11
External pressure
The external pressure (in the air) can be between 0 and
3 bar.
Deposits
Dust, dirt and other foreign matter must not be allowed to
accumulate sufficiently to divert some of the measuring
force onto the housing, thus distorting the measured
value (force shunt).

Mechanical installation
12 A4303-1.0 HBM: public K-LK1/600N-WH
5 Mechanical installation
Important mounting instructions
SHandle the transducer with care
SUse suitable tools
SThe mounting surfaces (load application parts) must
- Be free of grease and dust
- have a hardness level of more than 43HRC
SDo not overload the transducer, even temporarily, for
example, due to unevenly distributed support loads.
SInitially use supports (blanks, dummies) that are the
same height when completing the adjustment work.
WARNING
Additional safeguards must be provided if there is a risk
that overloading the transducer may cause it to break,
which could put people at risk.
General installation guidelines
The forces to be measured must act on the transducer
as accurately as possible in the direction of measure
ment. Torques and bending moments, eccentric loading
and lateral forces may produce measurement errors and
destroy the transducer, if limit values are exceeded.

6 Electrical installation
Notes on cabling
Electrical and magnetic fields often induce interference
voltages in the measuring circuit. These interferences
arise primarily from power lines lying in parallel to the
measuring leads, but also from contactors or electric mo
tors in the vicinity. In addition, interference voltages can
be induced galvanically, especially through the grounding
of the measurement chain at several points.
Please follow the instructions below:
SOnly use shielded, low-capacitance measurement
cables for extensions (HBM cables fulfill both condi
tions).
SDo not route measurement cables parallel to power
lines and control circuits. If this is not possible (in
cable pits, for example), protect the measurement
cable with a rigid steel conduit, for example, and keep
it at least 50 cm away from the other cables. The
power lines or control circuits should be twisted (15
twists per meter).
SAvoid stray fields of transformers, motors and con
tactors.
SDo not ground the transducer, amplifier and indicator
more than once. All the devices in the measurement
chain must be connected to the same grounded con
ductor.
SThe connection cable shield is connected to the trans
ducer housing.

CAUTION
Caution with very long cables.
Cable connection
Only use shielded and low-capacitance measurement
cables. Ensure that the connection is perfect and that it
has a low contact resistance. We recommend implement
ing extensions using six-wire configuration to exclude
changes to the sensitivity.
