2 Application

T10F Torque Flanges acquire static and dynamic torque data from static or
rotating shafts and determine rotation speed together with information on the
direction of rotation. Due to their extremely short design they enable very
compact test arrangements to be used. They offer a very wide range of
applications.

In addition to conventional test-rig applications (motor, roller and gear
test-rigs) new solutions are possible for torque measurements partly
integrated into the machines. Here you benefit from the special characteristics
of the T10F Torque Flange:

• Extremely short design due to flange measuring–body

• High permissible dynamic loads

• High permissible transverse forces and bending moments

• Very high torsional stiffness

• No bearings, no slip-rings

Due to their construction without bearings and the contact–free transmission
of excitation voltage and measurement, torque flanges are maintenance–free.
Thus, frictional or thermal effects on the bearings can be excluded.

The torque flanges are supplied for nominal (rated) torques from 50 N⋅m up to
10 kN⋅m. Depending on the nominal torque, maximum speeds of up to
15,000 rpm are permissible.

T10F Torque Flanges are protected from electromagnetic interference. They
have been tested with regard to EMC according to the relevant European
standards, and carry the CE mark.

3 Design and function

Torque flanges consist of two separate parts: the rotor and the stator. The
rotor includes the measuring body and the adapter flange.

Strain gauges have been mounted on the measuring body. The rotor
electronics for transmitting the bridge excitation voltage and measuring signal
are located centrally on the flange. The top surface of the measuring body
supports the transmitter coils for contact–free transmission of excitation
voltage and measuring signal. The signals are transmitted and received by a
divisible antenna ring. The antenna ring is mounted on a housing that includes
the electronic system for voltage adaption and signal conditioning.

The stator includes connecting plugs for the torque signal, the power supply
and the rotation speed signal (optional). The antenna ring should be mounted
concentrically around the rotor (see chapter 4).

In the case of the option which includes a rotation speed measurement
system, the rotation speed sensor is mounted on the stator and the customer
fastens the associated slotted disc to the rotor. Rotation speed is measured
optically in accordance with the principle of infrared transmitted light barriers.

4 Mechanical installation

WARNING

Handle the torque flange carefully. The transducer might suffer
permanent damage from mechanical shock (dropping), chemical effects
(e.g. acids, solvents) or thermal effects (hot air, steam).

Never slacken the screwed rotor joints marked with sealing varnish (the
hexagon-socket screws for the measuring body and adapter flange and
the slotted screws on the type plate).

With alternating loads, you should use a screw locking device (medium)
to glue the rotor connection-screws into the counter thread in order to
prevent slackening and loss of pre–tensioning.

T10F Torque Flanges can be fitted directly to an appropriate shaft flange. The
adapter flange enables direct mounting of a cardan shaft or corresponding
corrector elements (if necessary, via an intermediate flange). Never exceed
the permissible limits specified for bending moments or for transverse and
longitudinal forces. Due to the high torsional stiffness of the T10F torque
flange, dynamic changes on the shaft run are minimized.

CAUTION

In all cases check the effect on critical speeds and natural torsional
vibrations to avoid overloading the torque flanges due to resonance
step-up.

NOTE

For regular operation observe the mounting dimensions in all cases (see
page 46) .

4.1 Conditions at the site of installation

T10F Torque Flanges are protected to IP54 according to EN 60 529. The
measuring flanges must be protected from dirt, dust, oil, solvents and
humidity. During operation, the prevailing safety regulations for the security of
personnel must be observed (see ”Notes on safety”).

The output signal and zero point of the T10F Torque Flange are compensated
for the effects of temperature variations between wide limits (see Technical
Data on page 48). This compensation is carried out by costly stove-processes
at static temperatures. This ensures that reproducible relationships are
present and that the characteristics of the transducers can be duplicated at
any time.

If static temperature relationships do not prevail, e.g. due to temperature
differences between the measuring element and the adapter flange, the
values specified in the technical data can be exceeded. Then for accurate
measurements, static temperature relationships must be obtained by cooling
or heating depending on the application. Alternatively, temperature
decoupling must be checked, e.g. by heat radiating elements such as
laminated couplings.

4.2 Mounting position

The torque flange can be mounted in any position. With clockwise torque, the
output frequency is 10...15 kHz. With HBM amplifiers or with the “Voltage
output” option, a positive output Signal (0...+10 V) is present.

In the speed measuring system, an arrow on the sensor head clearly indicates
the direction of rotation. When the torque flange rotates in the direction of the
arrow, connected HBM amplifiers deliver a positive output signal (0...+10 V).

4.3 Installation options

In principle, there are two options for torque-flange mounting: with antenna
ring complete or disassembled. We recommend fitting in accordance with
chapter 4.3.1. If it is not possible to install in accordance with 4.3.1 (for
example during a subsequent stator change, or when installing with the speed
measuring system), you must dismantle the antenna ring. At this point please
be sure to follow the instructions for assembling the antenna segments (see
”Installing the stator” and “Installing the slotted disc”).

4.4 Installing the rotor

CAUTION

For regular operation observe the mounting dimensions in all cases (in
particular area of metal parts, see page 46) .

Additional mounting instructions for the speed measuring system can be
found in chapter 4.7, page 23.

NOTE

In general, the rotor type-plate will no longer be visible after installation.
Therefore, additional adhesive labels including the major characteristics
have been supplied. They can be fixed on the stator or other relevant
test-rig components thus enabling required data such as e.g. the
calibration signal to be read off at any time.

1. Prior to installation, clean the plan surfaces on the torque flange and
counter flange. For safe torque transmission, the surfaces must be clean
and free from grease. Use a piece of cloth or paper soaked with a solvent.
Make sure that no solvent drips into the torque flange’s interior and that the
transmitter coils do not suffer damage.

2. To screw–fasten the measuring body use eight DIN EN ISO 4762

hexagon–socket screws, property class 10.9 (measuring range
10 kNVm: 12.9), of the appropriate length (depending on the connection

geometry, see Table 4.1).
We recommend, particularly for 50 N⋅m, 100 N⋅m and 200 N⋅m situations,

fillister-head screws DIN EN ISO 4762 or similar, blackened,
smooth-headed, permitted size and shape variance in accordance with
DIN ISO 4759, Part 1, product class A.

WARNING
The screw heads (Z), see Fig. 4.1, must not fit tight to the adapter flange.
With alternating load: Use a screw locking device (e.g. LOCTITE no. 242)

to glue the screws into the counter thread in order to prevent slackening
and loss of pre–tensioning.

3. Before finally tightening the screws, turn the torque flange on the centering

until all screw heads are located more or less centrally in the clearance
bores on the connection element. The screw heads may in no case be in
contact with the sides of the adapter-flange clearance-bores.

4. Fasten all screws with the specified fastening torque (Table 4.1).

5. For further installation of the shaft run, there are eight threaded bores on

the adapter flange. Also use screws of property class 10.9 (or 12.9) and
fasten with the fastening torque specified in Table 4.1.

4.5 Installing the stator B

On delivery, the stator is installed and ready for operation. The antenna
segments can be separated from the stator, for example, for maintenance or
to facilitate stator installation. In order not to alter the central alignment of the
segment rings in relation to the stator foot, we recommend you remove only
one antenna segment from the stator.

If your application does not require stator disassembly, proceed as described
in sections 2., 6., 7. and 8.

Version with speed measuring system

Since the rotation speed sensor surrounds the slotted disc, it is not possible to
slide the stator axially over the ready–fitted rotor (except for the 50 N⋅m,
100 N⋅m and 200 N⋅m ranges). Please also note chapter 4.7 on this point.

Fig. 4.2: Antenna-segment screwed connections

1. Slacken and remove the screwed connections (M6) on one antenna
segment. Make sure that the serrated locking washers are not lost.

2. Use an appropriate foundation plate to install the stator housing in the
shaft run, in such a way that it is still possible to make horizontal and
vertical adjustments. Do not fully tighten the screws yet.

3. Now refit the antenna segment removed under point 1. onto the stator
using two hexagon–socket screws and the serrated locking washers. Make
sure that for a defined transition resistance all required serrated locking
washers (see Fig. 4.2), die f are located under the nuts. Do not fully tighten
the screws yet.

4. Fit the upper screws for connecting the two antenna segments so that the
antenna ring is closed. Remember the serrated locking washers in this
case, too.

5. Now, fasten all antenna-segment screwed connections with a tightening
torque of 5 N⋅m.

6. Align the antenna and rotor so that the antenna encloses the rotor more or
less coaxially. Please adhere to the permitted alignment tolerances
specified in the technical data.

7. Fasten the stator-housing screwed connection.

8. Make sure that the opening in the lower
antenna-segment section is free from electroconductive
foreign substances.

CAUTION

In order to ensure proper functioning, the serrated locking washers (A5,
1–EST Din 6796 ZN/galvanised) must be renewed after the antenna
screws have been loosened three times.

Depending on the operating conditions, the antenna ring may be excited so
that it vibrates. This effect is dependent on

• the speed

• the antenna diameter (depends in turn on the measurement range)

• the construction of the machine foundations

To avoid vibrations, a clamping piece is enclosed with the torque
measurement flange enabling the antenna ring to be supported.

The slotted disc for the speed measuring system is not fitted to the rotor in
order to avoid damage in transit. It must be fastened to the adapter flange (or
intermediate flange) before installing the rotor in the shaft run. The associated
rotation speed sensor is already fitted to the stator.

The necessary screws, screwdriver and screw lock are included among the
components supplied.

4.8 Aligning the stator (speed measuring system)

The stator can be installed in any position required (for example it can be
installed “upside down”).

For measuring mode to operate perfectly, the slotted disc for the speed
measuring system must rotate at a defined position in the sensor fork.

Axial alignment

The sensor fork is provided with an alignment mark for axial alignment. In its
installed status the slotted disc must be positioned exactly over this alignment
mark. Variances of up to "2mm are permitted in measuring mode (total static
and dynamic displacement).

Alignment mark

NOTE
For fastening the stator we recommend M6 screws with packing
washers (elongated hole width 9 mm). Using this size of screw ensures
the necessary degree of mobility for alignment.

5 Electrical connection

5.1 Shielding design

The cable screen is connected according to the HBM Greenline concept, thus
enclosing the measuring system (without rotor) in a Faraday cage (for this it is
important that the shielding on both cable ends is laid flat to the body of the
casing) and preventing potential electromagnetic interferences from affecting
the measuring signal. Special electronic coding methods are used to protect
the transmission path and the rotor from electromagnetic interferences.

In the case of interferences due to potential differences (compensating
currents), operating-voltage zero and housing ground must be disconnected
on the amplifier and a potential-equilibration line between stator housing and
amplifier housing must be established (copper conductor, 10 mm

2

wire

cross-section).
If potential differences between the rotor and the stator occur in the machine,

due perhaps to unchecked leakage, and give rise to interference, the situation
is usually remedied by fully earthing the rotor, for instance with a wiper or
brush. The stator must be similarly earthed.

5.2 Option 2, code KF1

On the stator housing is a 7–pin device connector (Binder 723), to which you
connect the cable for the power supply and torque signal.

5.2.1 Adapting to the cable length

The way the torque flange operates is dependent on the method used for
transmission between the rotor and the stator, and the following:

• Installation situation (e.g. cover, area free of metal)

• Length of cable

• Excitation voltage supply tolerances

For adaptation to different ratios, there are three switches in the stator
housing which are accessible when the stator cover is removed.

5.4 Supply voltage

The supply voltage has been designed for DC voltage operation (18...30V).
The circuit is intended for use with a safety extra–low voltage (SELV circuit).
It is not intended for connection with a DC supply network according to
EN 61010–1.

The notes in this chapter refer to standalone operation of the T10F without
HBM system solutions.

The supply voltage is galvanically isolated from signal outputs and calibration
signal inputs. Connect an extra–low safe voltage of 18 V...30 V to pin 3 (+)
and pin 2 (

) of connector 1 or connector 3. We recommend that you use
HBM cable KAB 8/00–2/2/2 and the appropriate connector jacks, since when
operated at nominal voltage (24 V) the cable can be up to 50 m long, or 20 m
long if within the nominal voltage range (see Accessories, page 47) . If the
permitted cable length is exceeded, you may supply the required voltage over
two cables connected in parallel (connectors 1 and 3). This enables you to
double the permitted length. Alternatively an on-site power pack should be
installed.

If you feed the supply voltage through an unshielded cable, the cable must be
twisted (interference suppression). We also recommend that a ferrite element
should be located close to the connection plug on the cable, and the stator
should be earthed.

CAUTION

At the instant of switching on, a current of up to 2 A may flow and this
may switch off power packs with electronic current limiters.

6 Calibration

T10F torque flanges deliver an electrical calibration signal which can be
picked up by the amplifier in the case of measuring systems using HBM com–
ponents. The torque flange generates a calibration signal of about 50 % of the
nominal torque. The precise value is specified on the type plate. Adjust the
amplifier output-signal to the calibration signal supplied by the connected
torque flange to adapt the amplifier to the torque flange.

In order to reproduce the measured values recorded in the test report, the
boundary conditions regarding the comparability (e.g. mounting position) must
be reproduced.

NOTE

The measurement flange should not be under load when the calibration
signal is being measured, since the calibration signal is mixed
additively.

CAUTION

To maintain measurement accuracy, the calibration signal should be
connected for no more than 5 minutes. A similar period is then needed
as a cooling phase before triggering the calibration signal again.

6.1 Calibration option 2, code KF1

The calibration signal is triggered by increasing the excitation voltage from
54 V

PP

to 80 V

PP

(pins 6 and 7, connector 1).

6.2 Calibration option 2, code SF1/SU2

The calibration signal is triggered by connecting an extra–low safe voltage of
5 V to pins 6 (+) and 7 (

) of connector 1 or connector 3.

The rated voltage for triggering the calibration signal is 5 V (triggered when
U>2.7 V). The trigger voltage is galvanically isolated from the supply voltage
and the measurement voltage. The maximum permitted voltage is 30 V

. At

voltages lower than 0.7 V, the measuring flange is in measurement mode.
Current drain at rated voltage is approx. 2 mA and at maximum voltage is
approx. 22 mA.

9 Maintenance

Torque flanges are maintenance–free.

9.1 Maintenance of the speed module

Depending on ambient conditions, the slotted disc on the rotor and the
associated sensor optics on the stator may become dusty in the course of
operation. This makes itself felt as a change of polarity in the display. If this
should happen the sensor and the slotted disc must be cleaned.

1. Clean the slotted disc using compressed air (up to 6 bar).

2. Carefully clean the sensor optics using a dry or spirit–moistened cotton
wool stick. Never use any other kind of solvent.

Fig. 9.1: Areas to clean on the rotation speed sensor

Each type of irregular stress can only be permitted with its given static load limit (bending moment, side
load or axial load, exceeding the nominal rotation speed ) if none of the others can occur. Otherwise the
limit values must be reduced. If for instance 30 % of the bending moment and also 30 % of the side load
are present, only 40 % of the axial load is permitted, provided that the nominal rotation speed is not
exceeded. In the measurement result, permitted bending moments, axial forces and lateral forces can
appear as approx. 1 % of nominal torque.

5)

In the T10F/50 N⋅m, it is permissible to exceed nominal torque by 100 %. In the T10F/100 N⋅m to 10 kN⋅m,
nominal torque must not be exceeded.
