1 Safety instructions
Designated use
The reference torque transducer TB2 is designed exclusively for use in torque
measurement tasks and directly associated control and regulating tasks. Use
for any additional purpose shall be deemed to be not as intended.
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. The same applies to the
use of accessories.
The transducer is not a safety element within the meaning of its designated
use. Proper and safe operation of this transducer requires proper transporta
tion, 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 failsafe. The trans
ducer can give rise to remaining dangers if it is inappropriately installed and
operated by untrained personnel.
Everyone involved with mounting, starting up, maintaining, or repairing the
transducer must have read and understood the Operating Manual and in partic
ular the technical safety instructions.
Residual dangers
The scope of supply and performance of the transducer covers only a small
area of torque measurement technology. In addition, equipment planners, in
stallers and operators should plan, implement and respond to the safety engi
neering considerations of torque measurement technology in such a way as to
minimize remaining dangers. On‐site regulations must be complied with at all
times. Reference must be made to remaining dangers connected with torque
measurement technology.

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 ex
clude all liability on our part for any damage resulting therefrom.
Qualified personnel
The transducer must only be installed and used by qualified personnel, strictly
in accordance with the specifications and with safety requirements and regula
tions. It is also essential to comply with the legal and safety requirements for
the application concerned during use. The same applies to the use of accesso
ries.
Qualified personnel means persons entrusted with siting, mounting, starting up
and operating the product who possess the appropriate qualifications for their
function.
Accident prevention
According to the prevailing accident prevention regulations, once the transduc
ers have been mounted, a covering agent or cladding has to be fitted as fol
lows:
SThe cover or cladding must not be free to rotate.
SThe cover or cladding should prevent squeezing or shearing and provide
protection against parts that might come loose.
SCovers and cladding must be positioned at a suitable distance or be
arranged so that there is no access to any moving parts within.
SCovering agents and cladding must also be attached if the moving parts of
the transducer are installed outside the movement and operating range of
persons.
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.

2.2 Symbols on the product
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 waste disposal mark
In accordance with national and local environmental
protection and material recovery and recycling regula
tions, old devices that can no longer be used must be
disposed of separately and not with normal household
garbage.
If you need more information about waste disposal,
please contact your local authorities or the dealer from
whom you purchased the product.

Application
TB2 A0884-8.0 HBM: public 7
4 Application
The transducer can measure static and dynamic torques in non‐rotating opera
tion. The nominal (rated) torques lie between 100 N⋅m and 10 kN⋅m.
Transfer torque transducer
The main applications are the transfer of torque, e.g. when calibrating refer
ence transducers in test and calibration equipment, and the comparison of ref
erence standards in different calibration laboratories.
A high degree of comparability is important in transfer transducers. Compara
bility is, with regards to transfer of torque, a parameter for different observers,
test conditions, laboratories, installation and time situations. The same installa
tion conditions must be reproduced as in the calibration with reference stan
dard or calibrated with appropriate adapters when transfered.
Reference torque transducer
Reference torque transducers are installed in a calibration device and subse
quently the entire calibration unit is qualified or certified, for instance with a
transfer torque transducer. The exact sensitivity of the transducer is therefore
of secondary importance.
General torque measurements in non‐rotating operation
Due to the high mechanical loading capacity, the permissible oscillation width
of 200 % (160 % at 3 to 10 kN⋅m) of the nominal (rated) torque and the com
pact design, this transducer is also high suitable for applications in test ma
chines for component tests (rotation reversal cycling). A design with degree of
protection IP67 per EN 60529 is optionally available.
Structure and mode of operation
8A0884-8.0 HBM: public TB2
5 Structure and mode of operation
The torque reference transducer consists of a measuring body, installed with
strain gages, with a flange‐type torque application. The SG are arranged so
that an optimal torque flow is ensured between the flange and the SG installa
tion point.
