Appropriate use
The T40FH 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 installed.
The torque flange may only be installed by qualified personnel 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 concerned. 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 "Additional safety precautions" section. Proper and safe operation
requires proper transportation, correct storage, siting and mounting, 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 specified maximum loads in particular must never
be exceeded. The values stated in the technical data sheets, forexample, must
not be exceeded for
S Limit torque,
S Longitudinal limit force, lateral limit force or bending limit moment,
S Torque oscillation width,
6 A4429-3.0 HBM: public T40FH
Safety instructions
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 man
ner, 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 "Load-carrying capacity limits", and to the specifications.
Accident prevention
According to the prevailing accident prevention regulations, once the transduc
ers have been mounted, a covering agent or cladding has to be fitted as fol
lows:
S The covering agent or cladding must not be free to rotate.
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 installed outside peoples' 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) implement any (safety-rele
vant) cutoffs. This requires additional 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.
T40FH A4429-3.0 HBM: public 7
Safety instructions
The scope of supply and performance of the transducer covers only a small
area of torque measurement technology. In addition, equipment planners,
installers and operators should plan, implement and respond to safety engi
neering considerations in such a way as to minimize residual dangers. Perti
nent 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 failsafe. Transduc
ers can give rise to residual dangers if they are incorrectly operated or inappro
priately mounted, installed and operated by untrained personnel. Every person
involved with siting, starting-up, operating or repairing a torque flange must
have read and understood the mounting instructions and in particular the tech
nical 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 instructions, these safety instructions or any other applicable
safety regulations (BG safety and accident prevention regulations) when using
the transducers. Transducers can break, particularly in the case of overloading.
The breakage 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 designated 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 affected (due to the torques acting on or
being monitored by the torque flange).
Conversions and modifications
The design or safety engineering of the transducer must not be modified with
out our express permission. 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 instructions must be included
with the torque flange.

Application
3 Application
The T40FH torque flange measures static and dynamic torques on stationary
and rotating shafts. Test beds can be extremely compact because of the com
pact design of the transducer. This offers a very wide range of applications.
The T40FH torque flange is reliably protected against electromagnetic interfer
ence. It has been tested in accordance with harmonized European standards
and/or complies with US and Canadian standards. The CE mark and/or the
FCC label are attached to the product.
12 A4429-3.0 HBM: public T40FH
Structure and mode of operation
4 Structure and mode of operation
The torque flange consist of two separate parts: the rotor and the stator. The
rotor comprises the measuring body and the signal transmission elements.
Strain gages (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 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 elec
tronic system for voltage adaptation and signal conditioning.
Connector plugs for the torque and rotational speed signals, the voltage supply
and the digital output are located on the stator. The antenna segments (ring)
should be mounted concentrically around the rotor (see Chapter 5).

Structure and mode of operation
The rotational speed sensor is mounted on the stator in Option 5 with a rota
tional speed measuring system. Rotational speed is measured magnetically by
a magnetic field dependent resistor and a ring gear attached to the rotor.

5.1 Important precautions during installation
Notice
A torque flange is a precision measurement element and therefore needs care
ful handling. Dropping or knocking the transducer may cause permanent dam
age. 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 rotational speeds and natural
torsional vibrations, to prevent the transducer being overloaded by reso
nance sharpness.
S Make sure that the transducer cannot be overloaded.
WARNING
There is a danger of the transducer breaking if it is overloaded. This can cause
danger for the operating personnel of the system in which the transducer is
installed.
Implement appropriate safety measures to avoid overloads 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 prestressing loss due to screw slackening, in
the event of alternating loads.
S Comply with the mounting dimensions to enable correct operation.
An appropriate shaft flange enables the T40FH torque flange to be mounted
directly. It is also possible to mount a joint shaft or relevant compensating ele
ment directly on the rotor (using an intermediate flange when required). Under
T40FH A4429-3.0 HBM: public 15
Mechanical installation
no circumstances should the permissible limits specified for bending moments,
lateral and longitudinal forces be exceeded. Due to the T40FH torque flange's
high torsional stiffness, dynamic shaft train changes are kept to a minimum.
Important
Even if the unit is installed correctly, the zero point adjustment made at the fac
tory 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 residual zero
drift when the unit is removed is greater than 1% of the characteristic value,
please send the transducer back to the Darmstadt factory for testing.
5.2 Conditions on site
The T40FH 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 out
put and zero signals of the transducer (see Chapter 15 “Specifications"). 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. In this case, ensure static temperature ratios
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 Mounting position
The torque flange can be mounted in any position.
With clockwise torque, the output frequency for Option 5, code DU2 is 60 … 90
kHz (Option 5, Code SU2: 10 … 15kHz; Option HU2: 240 … 360kHz). In con
junction 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 identify the direc
tion of rotation: If the measurement flange moves in the direction of the arrow,
connected HBM measuring amplifiers deliver a positive output signal.
16 A4429-3.0 HBM: public T40FH
Mechanical installation
With the non-rotating version, there is a positive output signal in mV/V for clock
wise torque.
5.4 Installation options
As its diameter 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. It is essential in
this case to comply with the notes on assembling the antenna segments (see
Section 5.7).

5.5 Preparing for the rotor mounting
CAUTION
The rotor is heavy (as much as 142 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 T40FH packaging
2. Fasten two equal-length ropes with sufficient load-carrying capacity 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).
T40FH A4429-3.0 HBM: public 19

3. Place the rotor on a clean and stable base.
4. Remove one of the eyebolts.
5. Carefully lift the rotor until it hangs free.
6. Carefully tilt the rotor by lowering it over the flange edge until it rests hori
zontally on both outer flange surfaces (see Fig. 5.3).
CAUTION
Crush hazard. Keep your hands and feet a safe distance away from the rotor.

7. Secure the rotor with wedges to stop it from rolling away.
8. Screw the second eyebolt back into the tapped holes in the outer flange sur
face.
9. Fasten the rotor to the hook of the crane with two equal-length ropes. The
rotor is now prepared for horizontal installation (see Fig. 5.4).

CAUTION
You must remove the eyebolts after mounting! Keep them safe for later use.
5.6 Mounting the rotor
Tip
Usually the rotor type plate is no longer visible after installation. 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 compo
nents. 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.
22 A4429-3.0 HBM: public T40FH
Mechanical installation
Notice
Make sure during installation that you do not damage the measuring zone
marked in Fig. 5.5 by using it to support tools or knocking tools against it when
tightening screws, for example. This can damage the transducer and produce
measurement errors, or even destroy the transducer.
1. Prior to installation, clean the plane faces of the transducer flange and the
counter flange.
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 winding.

2. For connection of the flange, (see Fig. 5.5) use hexagon screws DIN 933 of
a suitable length (dependent on the connection geometry, see Tab. 5.1 on
Page 24).
3. Fasten all screws with the specified torque (Tab. 5.1 on Page 24).
T40FH A4429-3.0 HBM: public 23

4. Now remove the ring bolts and mounting ring(s).
Important
Keep them in a safe place for future dismounting.
Important
Use a threadlocker (medium strength, e.g. LOCTITE) to glue the screws into
the counter thread to exclude prestressing loss due to screw slackening, in the
event of alternating loads.
Notice
Comply with the maximum thread reach as per Tab. 5.1, Page 24. Otherwise
significant measurement errors may result from a torque shunt, or the trans
ducer may be damaged.

Important
Dry screw connections can result in different and higher friction factors (see
VDI 2230, for example). This means a change to the required tightening
torques.
The required tightening torques can also change if you use screws with a sur
face or property class other than that specified in Tab. 5.1, as this affects the
coefficient of friction.
5.7 Installing the stator
On delivery, the stator has already been installed and is ready for operation.
The upper antenna segment can be separated from the stator, for example, for
maintenance or to facilitate stator installation.

1. Undo and remove both the bolted connections (M4+M5) on the upper
antenna segment.
T40FH A4429-3.0 HBM: public 25
Mechanical installation
There are fan-type lock washers (M4+M5) between the antenna segments:
make sure that they do not get lost.
2. Use an appropriate mounting base to install the stator housing in the shaft
train, so that there is sufficient opportunity for horizontal and vertical adjust
ments. Do not fully tighten the screws yet.
3. Now use four hexagon socket screws to mount the upper antenna segment
removed in Point 1. on the lower antenna segment.
Make sure that the fan-type lock washers are inserted between the antenna
segments (these ensure that there is a defined contact resistance)!
Important
To guarantee that they function perfectly, the fan-type lock washers (A5, 3-FST
DIN 6798 ZN/galvanized) must be replaced after the bolted antenna connection
has been loosened three times.
4. Now tighten all the bolted antenna segment connections with a tightening
torque of 5 N⋅m.
5. Then align the antenna to the rotor in such a way that the antenna encloses
the rotor more or less coaxially and the antenna wire in the axial direction
has the same position as the center of the transmitter winding on the rotor.
To make alignment easier, the outer edge of the stator antenna segment
and the outer edge of the stator winding carrier should be on the same line
(in alignment). Conform to the permissible alignment tolerances stated in
the specifications.
6. Now fully tighten the bolted stator housing connection.
Prevention of axial stator oscillation
Depending on the operating conditions, stator oscillation may be induced. This
effect is dependent on:
S the rotational speed,
S the antenna diameter (depends in turn on the measuring range),
S the construction of the machine base.
26 A4429-3.0 HBM: public T40FH
Mechanical installation
Important
To avoid axial oscillation, a clamp fixture is enclosed with the torque transducer
to enable the antenna ring to be supported. There is a hole, 6.5 mm in diame
ter, on the upper antenna segment to receive the clamping device (see
Fig. 5.7).
The cable plug (not included in the scope of supply) also requires support in
this case; a construction example is shown in Fig. 5.9.
Fig. 5.7 Construction example for supporting the antenna ring
7. Fasten the clamp fixture with the enclosed bolted connection, as shown in
Fig. 5.8. Clamp a suitable support element (we recommend a Ø 3-6 mm
threaded rod) between the upper and lower parts of the clamp fixture and
tighten the clamping screws.
