1 Safety instructions
Use in accordance with the regulations
Torque transducer T20WN is used exclusively for torque
and rotation speed measurement tasks and control and
adjustment tasks directly connected thereto. 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 Operating Manual. 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 mean
ing of its use as intended. Proper and safe operation of
this transducer requires proper transportation, correct
storage, assembly and mounting and careful operation.
General dangers of failing to follow the safety
instructions
The transducer corresponds to the state of the art and is
fail‐safe. The transducer can give rise to remaining
dangers if it is inappropriately installed and operated by
untrained personnel.
Everyone involved with the installation, commissioning,
maintenance or repair of the transducer must have read
and understood the Operating Manual and in particular
the technical safety instructions.
Remaining dangers
The scope of supply and performance of the transducer
covers only a small area of torque measurement
technique. In addition, equipment planners, installers and
Safety instructions
4 A0726-14.0 T20WN
operators should plan, implement and respond to the
safety engineering considerations of torque
measurement technique in such a way as to minimise
remaining dangers. Prevailing regulations must be
complied with at all times. Reference must be made to
remaining dangers connected with torque measurement
technology.
In this Operating Manual remaining dangers are pointed
out using the following symbols:
Symbol Significance
CAUTION This marking warns of a potentially dangerous
situation in which failure to comply with safety
requirements can result in slight or moderate physical
injury.
Note This marking draws your attention to a situation in
which failure to comply with safety requirements can
lead to damage to property.
Emphasis
See….
Italics are used to emphasize and highlight text and
references to other chapters and external documents.
CE mark
The CE mark enables the manufacturer to guarantee that
the product complies with the requirements of the rele
vant EC directives (the declaration of conformity is avail
able at http://www.hbm.com/HBMdoc).
Statutory marking requirements for waste disposal
National and local regulations regarding the protection of
the environment and recycling of raw materials require
old equipment to be separated from regular domestic
waste for disposal.
Safety instructions
T20WN A0726-14.0 5
For more detailed information on disposal, please contact
the local authorities or the dealer from whom you pur
chased the product.
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
The transducer must only to be installed and used by
qualified personnel, strictly in accordance with the
specifications and with safety requirements and
regulations. 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.
Qualified personnel means persons entrusted with the
installation, fitting, commissioning and operation of the
product who possess the appropriate qualifications for
their function.
Prevention of accidents
In accordance with the health and safety regulations
relevant to accident prevention, once the operator has
fitted the torque transducer, a cover or cladding must be
attached as follows:
SThe cover or cladding must not be free to rotate.
SThe cover or cladding must prevent access to any
areas where crushing or shearing could occur, and
must provide protection against any parts that may
come loose.
Application
6 A0726-14.0 T20WN
SCovers and cladding must be positioned at a suitable
distance or so arranged that it prevents access to any
moving parts within.
SCovers and cladding must also be attached if the
moving parts of the torque transducers are installed
outside the area in which people are moving about
and working.
The only permitted exceptions to the above requirements
are if the various parts and assemblies of the machine
are already fully protected by the design of the machine
or by existing safety precautions.
2 Application
Torque transducer T20WN measure static and dynamic
torque and rotation speeds or angles of rotation for
turning or static machine parts in any direction of rotation.
It is designed for small to medium‐sized torque, such as
that measured on performance or function test benches
for domestic or business machines.

3.3 Couplings
HBM supplies bellows‐type couplings for the installation
of torque transducers. When prepared for delivery, the
couplings and the torque transducer are kept separate.
The following points must be observed during installation:
SOnly tighten the clamping screws of the couplings
once the shafts are installed in the coupling hubs!
SThe bellows‐type coupling must not be overstretched
beyond the specified permissible flexibility.
SDrive and output shafts must be without burr.
SRun the shaft diameter with j6 tolerance, to produce
the preferred fit H7/j6.
3.3.1 Installation position with couplings
With the bellows‐type couplings, the T20WN torque
transducer can be operated in any installation position
(horizontal, vertical or diagonal). With vertical and diago
nal operation, make sure that additional frames are ade
quately supported.
3.3.2 Installation
1. Degrease the hub bore of each coupling half member
and the shaft ends with solvent (for example,
acetone).
2. Push the hub onto the shaft, set the reference gap L
(making use of the full clamping length of the
coupling) and align the shafts.
