Prevention of accidents
According to prevailing accident prevention regulations, after fitting the T10FH
torque flange a cover must be fitted as follows:
•The cover must not be able rotate.
•The cover shall protect against crushing or cutting and provide protection
against parts that might come loose.
•The cover shall be installed at a safe distance from moving parts or shall
prevent anyone putting their hand inside.
•The cover shall even be fitted if the moving parts are installed in areas to
which persons do not usuallyhave access.
The above regulations mayonlybe disregarded if machine parts are already
sufficientlyprotected owing to the design of the machine or because other
precautions have been taken.
Guarantee
In the event of a claim, the guarantee can onlybe considered if the torque
flanges are returned in its original packing.

1Scope of supply
•Torque flange
•Mounting Instructions
•Test record
•Optional:
Magnetic speed measuring system
PTB calibration certificate in accordance with DIN51309 or EA10/14:
Class 0.5
2Application
The T10FHtorque flange records static and dynamic torque on fixed or rotat
ing shafts and also return RS422 signals with direction of rotation information
to determine the speed.
The rotating version (frequencyand voltage output) is designed for:
•marine engine test benches
•transmissions
•pump test benches
The non−rotating version (mV/V output signal) is designed for:
•calibration tasks
•torque reference transducers
•torque transfer transducers
Designed to workwithout bearings and with contactless digital signal trans
mission, 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−1are permissible.
The T10FHtorque flange is reliablyprotected against electromagnetic inter
ference. It has been tested with regard to EMCaccording to the relevant Eu
ropean standards, and carries the CE mark.

3 Structure and mode of operation
The torque flange (Option 2, code N) consists of two separate parts: the rotor
and the stator.
The rotor comprises the measuring bodyand the signal transmission ele
ments.
Strain gages (SGs) are mounted on the measuring body. The rotor electronics
for transmitting the excitation voltage and the measurement signal are located
centrallyin the flange. The transmitter coils for the noncontact transmission of
excitation voltage and measurement signal are located on the measuring
body. The signals are sent and received bya separable antenna ring. The an
tenna ring is mounted on a housing that includes the electronic system for
voltage adaptation and signal conditioning.
Connectors for the torque signal, the voltage supplyand the speed signal (op
tion) are located on the stator. The antenna ring should be mounted more or
less concentricallyaround the rotor (see chapter 4).
Speed measurement is effected bya magnetic field dependent resistor and a
ring gear attached to the rotor.

4Mechanical installation
WARNUNG
Handle the torque flange carefully. The transducer might suffer perma
nent damage from mechanical impact (e.g. dropping), chemical effects
(e.g. acids, solvents) or thermal effects (e.g. hot air, steam).
Withalternating loads, you shouldcement the rotor connectionscrews
intothe mating threadwitha screw locking device (medium strength) to
exclude prestressing loss due toscrew slackening.
An appropriate shaft flange enables the T10FHtorque flange to be mounted
directly. It is also possible to directlymount a joint shaft or relevant compen
sating elements on the opposite flange (using an intermediate flange when re
quired). 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 oscillations critical to
bending, toprevent the transducer being overloadedby increases in
resonance.
NOTE
Evenif the unit is installedcorrectly, the zeropoint adjustment made at
the factory canshift by approx."150 Hz. If this value is exceeded, we
advise you tocheck the mounting conditions. If the residual zerooffset
whenthe unit is removedis greater than"50 Hz, please send the trans
ducer back tothe Darmstadt factory for testing.
For correct operation, do inany case observe the mounting dimensions
(see page 50).

12 T10FH
HBM A2037−4.0en
4.1 Conditions on site
The T10FHtorque flange is protected to IP54 according to EN60529. Protect
the transducer from coarse dirt, dust, oil, solvents and moisture. During opera
tion, the prevailing safetyregulations for the securityof personnel must be ob
served (see "SafetyInstructions").
There is wide ranging compensation for the effects of temperature on the out
put and zero signals of the T10FHtorque flange (see specifications on
page 41). This compensation is carried out at static temperatures. This guar
antees that the circumstances can be reproduced and the properties of the
transducer can be reconstructed at anytime.
If there are no static temperature ratios, for example, because of the tempera
ture differences between flange A and flange B, the values given in the speci
fications can be exceeded. Then for accurate measurements, you must en
sure static temperature ratios bycooling or heating, depending on the
application. As an alternative, checkthermal decoupling, bymeans of heat ra
diating elements such as multiple disc couplings.
4.2 Mounting position
The transducer can be mounted in anyposition. With clockwise torque, the
output frequencyis 10...15kHz (Option 3, Code SU2). In conjunction with
HBM amplifiers or when using the voltage output, a positive output signal (0V
to +10V) is present.
With counterclockwise torque, the output frequencyis 5kHz to 10kHz.
In the case of the speed measuring system, an arrowis attached to the head
of the sensor to clearlydefine 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.
4.3 Mounting sequence
As the diameter of the antenna ring is less than the flange diameter of the ro
tor, 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 before
hand.

4.4 Preparing for the rotor mounting
CAUTION
The rotor is heavy (as muchas 148 kg, depending on the measuring
range)! Use a crane or other suitable lifting equipment tolift it out of its
packaging and install it.
Whenworking withthe crane, be sure tomeet relevant safety require
ments and wear safety boots.
1. Remove the top layer of foam packaging.
Fig.4.1: T10FHpackaging
2. Fasten two equal−length ropes of sufficient bearing strength to the eye
bolts (each of the two ropes must be able to bear the full weight of the ro
tor) and hoist the rotor out of its packaging with the crane (see Fig.4.2).

4.5 Mounting the rotor
NOTE
Ingeneral, the rotor identification plate is no longer visible after installa
tion. This is why we include withthe rotor additional stickers withthe
important ratings, whichyou canattachtothe stator or any other rele
vant test−benchcomponents. You canthenrefer tothem whenever there
is anything you wishtoknow, suchas the shunt signal. Toexplicitly as
sign the data, anidentification number is attachedon the rotor where it
canbe seenfrom outside(see Fig.4.5).
1. Prior to installation, clean the measurement flange’s and counter flanges’
plane surfaces. For safe torque transfer, the surfaces 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 coils.
