Appropriate use
The T40FM 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 in
stalled.
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 section: "Additional
safety precautions". Proper and safe operation requires
6 A3276-8.0 HBM: public T40FM
Safety information
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. The respective spe
cified maximum loads in particular must never be ex
ceeded. For example, the values stated in the specifica
tions must not be exceeded, e.g. for
S Limit torque
S Longitudinal limit force, lateral limit force or limit bend
ing moment
S Torque oscillation width
S Breaking torque
S Temperature limits
S 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 "Loading 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.
T40FM A3276-8.0 HBM: public 7
Safety information
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 in
stalled 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.
Additional safety precautions
The torque flange cannot (as a passive transducer) im
plement any (safety-relevant) cutoffs. This requires addi
tional components and constructive measures, for which
the installer and operator of the plant is responsible. 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 techno
logy. In addition, equipment planners, installers and oper
ators should plan, implement and respond to safety en
gineering 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 moun
8 A3276-8.0 HBM: public T40FM
Safety information
ted, installed and operated by untrained personnel. Every
person involved with siting, starting-up, operating or re
pairing a torque flange must have read and understood
the mounting instructions and in particular the technical
safety instructions. The transducers can be damaged or
destroyed by non-designated use of the transducer or by
non-compliance with the mounting and operating instruc
tions, these safety instructions or any other applicable
safety regulations (safety and accident prevention regula
tions), when using the transducers. Transducers can
break, particularly in the case of overloading. The break
age of a transducer can also cause damage to property
or injury to persons in the vicinity of the transducer.
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.

3 Applications
The T40FM 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.

Structure and Mode of Operation
4 Structure and Mode of Operation
The torque flange consists of two separate parts: the ro
tor and the stator. The rotor comprises the measuring
body and the signal transmission elements.
Strain gauges (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 an
tenna 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 (ring) should be moun
ted concentrically around the rotor (see Chapter 5).

5.1 Important precautions during installation
Notice
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
T40FM A3276-8.0 HBM: public 19
Mechanical installation
S Comply with the mounting dimensions to enable cor
An appropriate shaft flange enables the T40FM 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 T40FM 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 adjust
ment made at the factory can shift by up to approx. 0.5%
of the characteristic value. If this value is exceeded, we
advise you to check the mounting conditions. If the resid
ual 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 T40FM 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 Chapter 14 "Specifications"). If there are no
static temperature ratios, for example, because of the
temperature differences between the measuring body
20 A3276-8.0 HBM: public T40FM
Mechanical installation
and the flange, the values given in the specifications can
be exceeded. In this case, ensure static temperature ra
tios 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 multiple
disc couplings.
5.3 Installation orientation
The torque flange can be installed with any orientation.
With clockwise torque, the output frequency is 60 …
90 kHz for Option 5, code DU2 (Option 5, code SU2: 10
… 15kHz; Option HU2: 240 … 360kHz). In conjunction
with HBM amplifiers or when using the voltage output, a
positive output signal (0 V …+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 dir
ection of rotation: if the measurement flange turns in the
direction of the arrow, connected HBM measuring amplifi
ers 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 pos
sible, (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 Preparing for the rotor mounting
The rotor is very heavy (depending on measuring range:
18kg … 39kg)!
Use a crane or other suitable lifting equipment to lift it out
of its packaging and install it.
Two eye bolts are screwed into the rotor as transport and
mounting aids. Hook the lifting equipment to these eye
bolts as this ensures that the rotor is lifted horizontally out
of the packaging (see Fig. 5.1).
CAUTION
Transport and mounting eye bolts

4. Clean the plane faces of the transducer flange and the
counter flange.
For safe torque transfer, the faces must be clean and
free from grease. Use a piece of cloth or paper
soaked in solvent. Make sure that no solvent drips into
the inside of the transducer and that the transmitter
coils are not damaged during cleaning.
5. Fasten the lifting equipment to the mounting eye
bolt(s).
6. Carefully lift up the rotor and move it to the mounting
position (see Fig. 5.1).

Mechanical installation
5.6 Mounting the rotor
Tip
Usually the rotor type plate is no longer visible after in
stallation. This is why we include with the rotor additional
stickers with the important characteristics, which you can
attach to the stator or any other relevant test-bench com
ponents. 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 identification number and
the size are engraved on the rotor flange, where they can
be seen from outside.
Notice
Make sure during installation that you do not damage the
measuring zone marked in Fig. 5.4 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.
1. Prior to installation, clean the plane faces of the trans
ducer flange and the counter flange.
For safe torque transfer, the faces must be clean and
free from grease. Use a piece of cloth or paper
soaked in solvent. When cleaning, make sure that you
do not damage the transmitter winding.
