Application
10 A2037-5.0 HBM: public T10FH
3 Application
The T10FH torque flange records static and dynamic
torque on fixed or rotating shafts and also return RS422
signals with direction of rotation information to determine
the speed.
The rotating version (frequency and voltage output) is
designed for:
Smarine engine test benches
Stransmissions
Spump test benches
The non-rotating version (mV/V output signal) is
designed for:
Scalibration tasks
Storque reference transducers
Storque transfer transducers
Designed to work without bearings and with contactless
digital signal transmission, the torque measuring system
is maintenance-free.
The torque flange is supplied for nominal (rated) torques
of 100 kN⋅m to 300 kN⋅m. Depending on the nominal
torque, maximum speeds of up to
3 000 min-1 are permissible.
The T10FH torque flange is reliably protected against
electromagnetic interference. It has been tested with
regard to EMC according to the relevant European stan
dards, and carries the CE mark.

Structure and mode of operation
T10FH A2037-5.0 HBM: public 11
4 Structure and mode of operation
The torque flange (Option 2, code N) consists of two sep
arate parts: the rotor and the stator.
The rotor comprises the measuring body and the signal
transmission elements.
Strain gages (SGs) are mounted on the measuring body.
The rotor electronics for transmitting the excitation volt
age and the measurement signal are located centrally in
the flange. The transmitter coils for the noncontact trans
mission of excitation voltage and measurement signal are
located on the measuring body. The signals are sent and
received by a separable antenna ring. The antenna ring
is mounted on a housing that includes the electronic sys
tem 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 concentri
cally around the rotor (see chapter 5, page 13).
Speed measurement is effected by a magnetic field
dependent resistor and a ring gear attached to the rotor.

5 Mechanical installation
WARNING
Handle the torque flange carefully. The transducer might
suffer permanent damage from mechanical impact (e.g.
dropping), chemical effects (e.g. acids, solvents) or ther
mal effects (e.g. hot air, steam).
With alternating loads, you should cement the rotor con
nectionscrews into the mating thread with a screw lock
ing device (medium strength) to exclude prestressing
loss due to screw slackening.
An appropriate shaft flange enables the T10FH torque
flange to be mounted directly. It is also possible to
directly mount a joint shaft or relevant compensating ele
ments on the opposite flange (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 torque
flange's high torsional stiffness, dynamic shaft train
changes are kept to a minimum.
CAUTION
Check the effect on speeds and natural torsional oscilla
tions critical to bending, to prevent the transducer being
overloaded by increases in resonance.

Mechanical installation
14 A2037-5.0 HBM: public T10FH
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 fac
tory for testing.
For correct operation, do in any case observe the mount
ing dimensions (see chapter 15, page 70).
5.1 Conditions on site
The T10FH torque flange is protected to IP54 according
to EN 60529. Protect the transducer from coarse dirt,
dust, oil, solvents and moisture. During operation, the
prevailing safety regulations for the security of personnel
must be observed (see ”Safety instructions”, page 5).
There is wide ranging compensation for the effects of
temperature on the output and zero signals of the T10FH
torque flange (see “Specifications” on page 56). This
compensation is carried out at static temperatures. This
guarantees that the circumstances can be reproduced
and the properties of the transducer can be recon
structed at any time.
If there are no static temperature ratios, for example,
because of the temperature differences between flange A
and flange B, the values given in the specifications can
be exceeded. Then for accurate measurements, you
must ensure static temperature ratios by cooling or heat
ing, depending on the application. As an alternative,

Mechanical installation
T10FH A2037-5.0 HBM: public 15
check thermal decoupling, by means of heat radiating
elements such as multiple disc couplings.
5.2 Mounting position
The transducer can be mounted in any position. With
clockwise torque, the output frequency is 10...15 kHz
(Option 3, Code SU2). In conjunction with HBM ampli
fiers or when using the voltage output, a positive output
signal (0 V to +10 V) is present.
With counterclockwise torque, the output frequency is
5 kHz to 10 kHz.
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. When the transducer rotates in the
direction of the arrow, a positive speed signal is output.
With the non-rotating version, there is a positive output
signal in mV/V for clockwise torque.
5.3 Mounting sequence
As the diameter of the antenna ring is less than the
flange diameter of the rotor, the antenna ring must be
dismantled for mounting. If access to the rotor in its
installed state is difficult, we recommend mounting the
antenna ring beforehand.

CAUTION
When installing the rotor, make sure that you do not
damage the stator. It is essential in this case to comply
with the notes on assembling the antenna segments (see
chapter 5.5 “Mounting the rotor”, page 22).

5.4 Preparing for the rotor mounting
CAUTION
The rotor is heavy (as much as 148 kg, depending on the
measuring range)! Use a crane or other suitable lifting
equipment to lift it out of its packaging and install it.
When working with the crane, be sure to meet relevant
safety requirements and wear safety boots.
1. Remove the top layer of foam packaging.
Fig. 5.1 T10FH packaging
2. Fasten two equal-length ropes of sufficient bearing
strength to the eyebolts (each of the two ropes must
be able to bear the full weight of the rotor) and hoist
the rotor out of its packaging with the crane
(see Fig. 5.2).
