2 Torque flange versions
In the case of option 2 “Electrical configuration", the
T10FS torque flange exists in versions KF1, SF1 and
SU2. The difference between these versions lies in the
electrical inputs and outputs on the stator, the rotors are
the same for all the versions of a measuring range.
Alternatively, versions SF1 and SU2 can be equipped
with a magnetic or optical speed measuring system (in
the case of the optical system, with or without a
reference pulse).

You can find out which version you have from the stator
identification plate. The version is specified in the
“T10FS-..." number there.
Example: T10FS-001R-SU2-S-0-V1-Y (see also
Page 89).

Application
T10FS A0785-150 HBM: public 15
3 Application
T10FS torque flanges record static and dynamic torque
on fixed or rotating shafts and also return RS-422 signals
with direction of rotation information to determine the
speed. With an optical speed measuring system, a
reference pulse can also be output with the speed
pulses. Test beds can be extremely compact because of
the short construction of the measurement flanges. They
offer a very wide range of applications.
In addition to conventional test‐bench engineering
(engine, roll and transmission test benches), new
solutions are possible for torque measurements partly
integrated in the machines. Here, you benefit in full from
the T10FS torque flange special characteristics:
low rotor weights
low mass moments of inertia
small outside diameters
no bearings, no slip rings
Thanks to the bearing‐free design and the contactless
transmission of excitation voltage and measured values,
there are no friction or bearing heating effects.
Torque flanges are supplied for nominal (rated) torques
from 100 N⋅m to 10 kN⋅m. Depending on the nominal
(rated) torque, maximum speeds of up to 24 000 min-1
are permissible.
T10FS torque flanges are reliably protected against
electromagnetic interference. They have been tested with
regard to EMC according to the relevant European
standards, and carry the CE mark.

Structure and mode of operation
16 A0785-150 HBM: public T10FS
4 Structure and mode of operation
Torque flanges consist of two separate parts: the rotor
and the stator. The rotor comprises the measuring body
and the signal transmission elements.
Strain gauges (SGs) are mounted 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 transmission 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. The antenna ring is
mounted on a housing that includes the electronic
system for voltage adaptation and signal conditioning.
Connectors for the torque signal, the voltage supply and
the speed signal (option) are located on the stator. The
antenna ring should be mounted more or less
concentrically around the rotor (see Chapter 5).
A magnetic or optical sensor performs the speed
measurement. With a magnetic measuring system, a
magnetized rotor is sampled by means of a
MagnetoResistive sensor (MR).
The optical sensor works on the infrared transmitted light
barrier principle. The reference pulse is generated by a
magnet in the slotted disc and a magnetoresistive
sensor. In the case of option 2 (speed measuring
system), code L, the speed sensor is mounted on the
stator, the customer attaches the associated slotted disc
on the rotor. In the case of code H, the slotted disc is
already mounted on the rotor.

5 Mechanical installation
WARNING
Handle the torque flange carefully! The transducer could
suffer permanent damage from mechanical shock
(dropping), chemical effects (e.g. acids, solvents) or
thermal effects (hot air, steam).
With alternating loads, you should cement the rotor
connection screws into the mating thread with a screw
locking device (medium strength) to exclude prestressing
loss due to screw slackening.
An appropriate shaft flange enables the T10FS torque
flanges 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 must the permissible
limits specified for bending moments, lateral and
longitudinal forces be exceeded. Due to the T10FS
torque flanges' high torsional stiffness, dynamic changes
on the shaft train are minimized.
Important
The effect on critical bending speeds and natural
torsional vibrations must be checked to avoid overloading
the measurement flanges due to the resonance stepup.

Mechanical installation
T10FS A0785-150 HBM: public 19
Notice
Even if the unit is installed correctly, the zero point
adjustment made at the factory can shift by
approx. ±150 Hz. 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 ±50 Hz,
please send the transducer back to the Darmstadt
factory for testing.
For correct operation, comply with the mounting
dimensions (see Page 85).
5.1 Conditions on site
T10FS torque flanges are protected to IP54 according to
EN 60529. They must be protected against coarse dirt
particles, dust, oil, solvents and humidity. During
operation, the prevailing safety regulations for the
security of personnel must be observed (see “Safety
instructions").
There is wide ranging compensation for the effects of
temperature on the output and zero signals of the T10FS
torque flange (see Specifications on Page 91). This
compensation is carried out at static temperatures in
extensive furnace processes. This guarantees that the
circumstances can be reproduced and the properties of
the transducer can be reconstructed at any time.
If there are no static temperature ratios, for example,
because of the temperature differences between the
measuring body and the flange, the values given in the
specifications can be exceeded. So for accurate
measurements, static temperature conditions must then
be obtained by cooling or heating depending on the

Mechanical installation
20 A0785-150 HBM: public T10FS
application. As an alternative, check thermal decoupling
by means of heat radiating elements such as multi‐disk
couplings.
5.2 Installation orientation
The measurement flange can be mounted in any
position. With clockwise torque, the output frequency is
10 kHz to 15 kHz. With HBM amplifiers or with the
“voltage output" option, a positive output signal (0 V ...
+10 V) is present.
In the case of the speed measuring system, an arrow is
attached to the head of the sensor to clearly define the
direction of rotation. If the measurement flange moves in
the direction of the arrow, connected HBM measuring
amplifiers deliver a positive output signal (0 V ... +10 V).
5.3 Installation options
In principle, there are two possibilities for torque flange
mounting: with the antenna ring complete or dismantled.
We recommend mounting as described in Chapter 5.3.1.
If installation in accordance with Chapter 5.3.1 is not
possible (e.g. in the case of subsequent stator
replacement or mounting with a speed measuring
system), you will have to dismantle the antenna ring. It is
essential in this case to comply with the notes on
assembling the antenna segments (see “Mounting the
stator" and “Mounting the slotted disc").
