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.

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.
