Appropriate use
The T40B torque flange is used exclusively for torque,
angle of rotation and power measurement tasks within
the load limits stipulated in the specifications. Any other
use is not appropriate.
Stator operation is only permitted when the rotor is
installed.
The torque flange may only be installed by qualified per
sonnel in compliance with the specifications and with the
safety requirements and regulations of these mounting
instructions. It is also essential to observe the applicable
legal and safety regulations for the application con
cerned. The same applies to the use of accessories.
The torque flange is not intended for use as a safety
component. Please also refer to the “Additional safety
precautions" section. Proper and safe operation requires
proper transportation, correct storage, siting and mount
ing, and careful operation.
Load carrying capacity limits
The data in the technical data sheets must be complied
with when using the torque flange. In particular, the
respective maximum loads specified must never be
exceeded. For example, the values stated in the specifi
cations must not be exceeded for
S limit torque,
S longitudinal limit force, lateral limit force or limit bend
ing moment,
S torque oscillation width,
T40B A3452-10.0 7
Safety instructions
S breaking torque,
S temperature limits,
S the limits of the electrical load‐carrying capacity.
Use as a machine element
The torque flange can be used as a machine element.
When used in this manner, it must be noted that, to favor
greater sensitivity, the transducer is not designed with
the safety factors usual in mechanical engineering.
Please refer here to the section “Load carrying capacity
limits" and to the specifications.
Accident prevention
According to the prevailing accident prevention regula
tions, once the transducers have been mounted, a cover
ing agent or cladding has to be fitted as follows:
S The covering agent or cladding must not be free to
rotate.
S The covering agent or cladding should prevent
squeezing or shearing and provide protection against
parts that might come loose.
S Covering agents and cladding must be positioned at a
suitable distance or be so arranged that there is no
access to any moving parts within.
S Covering agents and cladding must still be attached
even if the moving parts of the torque flange are
installed outside people's movement and working
range.
The only permitted exceptions to the above requirements
are if the torque flange is already fully protected by the
design of the machine or by existing safety precautions.
8 A3452-10.0 T40B
Safety instructions
Additional safety precautions
The torque flange cannot (as a passive transducer)
implement any (safety‐relevant) cutoffs. This requires
additional components and constructive measures, for
which the installer and operator of the plant is responsi
ble. The electronics conditioning the measurement signal
should be designed so that measurement signal failure
does not subsequently cause damage.
The scope of supply and performance of the transducer
covers only a small area of torque measurement technol
ogy. In addition, equipment planners, installers and oper
ators should plan, implement and respond to safety engi
neering considerations in such a way as to minimize
residual dangers. Pertinent national and local regulations
must be complied with.
General dangers of failing to follow the safety
instructions
The torque flange corresponds to the state of the art and
is reliable. Transducers can give rise to residual dangers
if they are incorrectly operated or inappropriately
mounted, installed and operated by untrained personnel.
Every person involved with siting, starting‐up, operating
or repairing a torque flange must have read and under
stood the mounting instructions and in particular the tech
nical safety instructions. The transducers can be dam
aged or destroyed by non‐designated use of the
transducer or by non‐compliance with the mounting and
operating instructions, these safety instructions or any
other applicable safety regulations (BG safety and acci
dent prevention regulations), when using the transducers.
Transducers can break, particularly in the case of over
loading. The breakage of a transducer can also cause
damage to property or injury to persons in the vicinity of
the transducer.
T40B A3452-10.0 9
Safety instructions
If the torque flange is not used according to the desig
nated use, or if the safety instructions or specifications in
the mounting and operating instructions are ignored, it is
also possible that the transducer may fail or malfunction,
with the result that persons or property may be adversely
affected (due to the torques acting on or being monitored
by the torque flange).
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.
Selling on
If the torque flange is sold on, these mounting instruc
tions must be included with the torque flange.

Qualified personnel means persons entrusted with siting,
mounting, starting up and operating the product, who
possess the appropriate qualifications for their function.
This includes people who meet at least one of the three
following requirements:

Application
3 Application
The T40B torque flange measures static and dynamic
torques on stationary and rotating shafts. Test beds can
be extremely compact because of the compact design of
the transducer. This offers a very wide range of applica
tions.
The T40B torque flange is reliably protected against elec
tromagnetic interference. It has been tested according to
harmonized European standards and/or complies with
US and Canadian standards. The product carries the
CE mark and/or FCC label.
14 A3452-10.0 T40B
Structure and mode of operation
4 Structure and mode of operation
The torque flange consists of two separate parts: the
rotor and the stator. The rotor comprises the measuring
body and the signal transmission elements.
Strain gages (SGs) are installed on the measuring body.
The rotor electronics for transmitting the bridge excitation
voltage and the measurement signal are located centrally
in the flange. The transmitter coils for contactless trans
mission of excitation voltage and measurement signal are
located on the measuring body's outer circumference.
The signals are sent and received by a separable
antenna ring. Separable antenna ring not for Option 7,
Code U. The antenna ring is mounted on a housing that
contains the electronics for voltage adaptation and the
signal conditioning.
Connector plugs for the torque and rotational speed sig
nals, the voltage supply and digital output, are located on
the stator. The antenna segments (the antenna ring)
must be mounted concentrically around the rotor (see
chapter 5).

5.1 Important precautions during installation
Note
A torque flange is a precision measuring element and
therefore needs careful handling. Dropping or knocking
the transducer may cause permanent damage. Make
sure that the transducer cannot be overloaded, including
while it is being mounted.
S Handle the transducer with care.
S Check the effect of bending moments, critical rota
tional speeds and natural torsional vibrations, to pre
vent the transducer being overloaded by resonance
sharpness.
Mechanical installation
S Make sure that the transducer cannot be overloaded.
WARNING
There is a danger of the transducer breaking if it is over
loaded. This can cause danger for the operating person
nel of the system in which the transducer is installed.
Implement appropriate safety measures to avoid over
loads and to protect against resulting dangers.
S Use a threadlocker (medium strength, e.g. LOCTITE)
to glue the screws into the counter thread to exclude
T40B A3452-10.0 21

S Comply with the mounting dimensions to enable cor
An appropriate shaft flange enables the T40B torque
flange to be mounted directly. It is also possible to mount
a joint shaft or relevant compensating element directly on
the rotor (using an intermediate flange when required).
Under no circumstances should the permissible limits
specified for bending moments, lateral and longitudinal
forces be exceeded. Due to the T40B torque flange's
high torsional stiffness, dynamic shaft train changes are
kept to a minimum.
Even if the unit is installed correctly, the zero point
adjustment made at the factory can shift by up to
approx. 2% of the sensitivity. If this value is exceeded,
we advise you to check the mounting conditions. If the
residual zero offset when the unit is removed is greater
than 1% of the sensitivity, please send the transducer
back to the Darmstadt factory for testing.

rect operation.
Important
5.2 Conditions on site
The T40B torque flange must be protected against
coarse dirt particles, dust, oil, solvents and moisture.
There is wide ranging compensation for the effects of
temperature on the output and zero signals of the trans
ducer (see “Specifications" section). If there are no static
temperature ratios, for example, because of the tempera
ture differences between the measuring body and the
22 A3452-10.0 T40B
Mechanical installation
flange, the values given in the specifications can be
exceeded. In this case, ensure static temperature ratios
by cooling or heating, depending on the application. As
an alternative, check if thermal decoupling is possible,
e.g. by means of heat radiating elements such as multi
ple disc couplings.
5.3 Installation orientation
The torque flange can be installed with any orientation.
With clockwise torque, the output frequency is 60 to
90 kHz for Option 5, Code DU2 (Option 5, Code SU2: 10
to 15 kHz; Option HU2: 240 to 360kHz). In conjunction
with HBM amplifiers or when using the voltage output, a
positive output signal (0 V to +10 V) is present. In the
case of the rotational speed measuring system, an arrow
is attached to the stator housing to clearly define the
direction of rotation: if the measurement flange turns in
the direction of the arrow, connected HBM measuring
amplifiers deliver a positive output signal.
5.4 Installation options
There are basically two options for mounting the torque
flange: with or without dismantling the antenna ring. We
recommend mounting as described in Chapter 5.4.1. If
mounting in accordance with Chapter 5.4.1 is not possi
ble, (e.g. in the case of subsequent stator replacement),
you will have to dismantle the antenna ring (only possible
for Option 7, Code S). It is essential in this case to com
ply with the notes on assembling the antenna segments
(see Chapter 5.4.2).

5.5 Installing the rotor
Usually the rotor type plate is no longer visible after
installation. This is why we include with the rotor addi
tional stickers with the important characteristics, which
you can attach to the stator or any other relevant
test‐bench components. You can then refer to them
whenever there is anything you wish to know, such as
the shunt signal. To explicitly assign the data, the identifi
cation number and the size are engraved on the rotor
flange, where they can be seen from outside.
Note
Make sure during installation that you do not damage the
measuring zone marked in Fig. 5.1 by using it to support
tools, or knocking tools against it when tightening screws,
for example. This can damage the transducer and pro
duce measurement errors, or even destroy the trans
ducer.
