Safety instructions
Use in accordance with the regulations
Z30, Z30–G type force transducers are used for high-precision force
measurements and for force reference measurements (transfer standard).
Use for any additional purpose shall be deemed to be not in accordance with
the regulations.
In the interests of safety, the transducer should only be operated as described
in the Mounting Instructions. It is also essential to observe the appropriate
legal and safety regulations for the application concerned during use. The
same applies to the use of accessories.
The transducer is not a safety element within the meaning of its use as inten-
ded. Proper and safe operation of this transducer requires proper transporta-
tion, correct storage, assembly and mounting and careful operation and main-
tenance.
General dangers of failing to follow the safety instructions
The Z30, Z30–G force transducer corresponds to the state of the art and is
fail-safe. The transducers can give rise to remaining dangers if they are
inappropriately installed and operated by untrained personnel.
Everyone involved with the installation, commissioning, maintenance or repair
of a force transducer must have read and understood the Mounting Instruc-
tions and in particular the technical safety instructions.
Remaining dangers
The scope of supply and performance of the transducer covers only a small
area of force measurement technique. In addition, equipment planners,
installers and operators should plan, implement and respond to the safety
engineering considerations of force measurement technique in such a way as
to minimise remaining dangers. Prevailing regulations must be complied with
at all times. There must be reference to the remaining dangers connected with
force measurement technique.

safety requirements could result in damage to property or some form of
physical injury.
Symbol: NOTE
Means that important information about the product or its handling is being
given.
Symbol:
Meaning: CE mark
The CE mark signals a guarantee by the manufacturer that his product meets
the requirements of the relevant EC directives (see Declaration of conformity
at the end of this document).

Prohibition of own conversions and modifications
The transducer must not be modified from the design or safety engineering
point of view except with our express agreement. Any modification shall
exclude all liability on our part for any damage resulting therefrom.
Qualified personnel
These transducers are only to be installed by qualified personnel strictly in
accordance with the technical data and with the safety rules and regulations
which follow. It is also essential to observe the appropriate legal and safety
regulations for the application concerned. The same applies to the use of
accessories.
Qualified personnel means persons entrusted with the installation, fitting,
commissioning and operation of the product who possess the appropriate
qualifications for their function.
Conditions on site
Protect the transducer from damp and weather influences such as rain, snow,
etc.
Maintenance
The Z30, Z30–G force transducer is maintenance free.
Accident prevention
Although the specified nominal force in the destructive range is several times
the full scale value, the relevant accident prevention regulations from the
trade associations must be taken into consideration.

2 Application notes
Force transducer Z30:
Series Z30 precision force transducers measure tensile and compressive
forces.
They measure static and quasi-static forces with great accuracy and
reproducibility and therefore require judicious handling. You must be
particularly vigilant when transporting and installing the devices. If the
transducers are dropped or jolted, permanent damage could be caused.
Z30–G force transducers complete with DKD certificate from HBM:
Force transducer calibrated to guaranteed class 00 according to DIN
EN10002–3 or ISO / FDIS 376.
As standard these transducers are calibrated in the tensile direction. On
request they can also be calibrated in the compressive direction to DKD
standards.
The limits for permissible mechanical, thermal and electrical stresses are
stated in the specifications. Be sure to allow for them when planning, installing
and operating the measurement configuration .

3 Structure and mode of operation
3.1 Measuring body
The measuring body comprises a system of measuring springs with strain
gauges (dual-beam spring element principle).
3.2 Housing
The enclosure provides protection against splashes and minor impacts.
3.3 Disturbance variables
Torsion, bending and transverse load are disturbance variables and are
therefore to be avoided. If necessary they can be remedied with HBM
mounting accessories (chapter 5.3 ).
The effects of temperature on the zero signal (S.G. bridge and housing) and
on the sensitivity are compensated.
Changes in the ambient pressure act as additive (subtractive) forces. These
are scarcely of importance when compared with large nominal loads.

4 Conditions on site
4.1 Ambient temperature
The effects of temperature on the zero signal and on the sensitivity are
compensated. To achieve optimal measurement results the nominal
temperature range must be maintained. Temperature-induced measurement
errors can be caused by uneven cooling or heating (for example by radiant
heat). A radiation shield and all-round heat insulation bring about marked
improvements. They must not form a force shunt.
4.2 Moisture
Extreme humidity or a tropical climate should be avoided if this means that the
classified limit values are exceeded (degree of protection IP50 under DIN EN
60529).
4.3 Air pressure
Changes in air pressure have no effect on the force transducer since it is not
hermetically sealed.
4.4 Chemical effects
The aluminium enclosures of the transducers is protected by a powder
coating. If used in difficult environmental conditions (direct weather effects,
contact with media which encourage corrosion) additional protective
measures should be employed by the user.
