Appropriate use
The T40FM 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 section: "Additional safety precautions". 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
6 A3276-11.0 HBM: public T40FM
Safety information
be exceeded. For example, the values stated in the specifications must not be
exceeded, e.g. for
S Limit torque
S Longitudinal limit force, lateral limit force or limit bending moment
S Torque oscillation width
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 de
signed with the safety factors usual in mechanical engineering. Please refer
here to the section "Loading capacity limits" and to the specifications.
Accident prevention
According to the prevailing accident prevention regulations, once the trans
ducers have been mounted, a covering agent or cladding has to be fitted as
follows:
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 people's 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.
T40FM A3276-11.0 HBM: public 7
Safety information
Additional safety precautions
The torque flange cannot (as a passive transducer) implement any (safety-rel
evant) 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.
The scope of supply and performance of the transducer covers only a small
area of torque measurement technology. In addition, equipment planners, in
stallers and operators should plan, implement and respond to safety engineer
ing considerations in such a way as to minimize residual dangers. Pertinent
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 reliable. Trans
ducers can give rise to residual dangers if they are incorrectly operated or inap
propriately mounted, installed and operated by untrained personnel. Every per
son 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 (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 ig
nored, it is also possible that the transducer may fail or malfunction, with the
result that persons or property may be adversely affected (due to the torques
acting on or being monitored by the torque flange).

Applications
3 Applications
The T40FM 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 T40FM torque flange is reliably protected against electromagnetic interfer
ence. It has been tested according to harmonized European standards and/or
complies with US and Canadian standards. The product carries the CE mark
and/or FCC label.
12 A3276-11.0 HBM: public T40FM
Structure and Mode of Operation
4 Structure and Mode of Operation
The torque flange consists of two separate parts: the rotor and the stator. The
rotor comprises the measuring body and the signal transmission elements.
Strain gauges (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 contains the elec
tronics for voltage adaptation and the signal conditioning.
Connector plugs for the torque and rotational speed signals, the voltage supply
and digital output, are located on the stator. The antenna segments (ring)
should be mounted concentrically around the rotor (see Chapter 5).

5.1 Important precautions during installation
Notice
A torque flange is a precision measuring element and therefore needs careful
handling. Dropping or knocking the transducer may cause permanent damage.
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 reson
ance 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 in
stalled.
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.
T40FM A3276-11.0 HBM: public 15
Mechanical installation
An appropriate shaft flange enables the T40FM 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
no circumstances should the permissible limits specified for bending moments,
lateral and longitudinal forces be exceeded. Due to the T40FM 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 fact
ory 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
offset when the unit is removed is greater than 1% of the sensitivity, please
send the transducer back to the Darmstadt factory for testing.
5.2 Conditions on site
The T40FM 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 14 "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 Installation orientation
The torque flange can be installed with any orientation.
With clockwise torque, the output frequency is 60 … 90 kHz for Option 5, code
DU2 (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
16 A3276-11.0 HBM: public T40FM
Mechanical installation
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 define the direction
of rotation: if the measurement flange turns in the direction of the arrow, con
nected HBM measuring amplifiers deliver a positive output signal.
5.4 Installation options
There are basically two options for mounting the torque flange: with or without
dismantling the antenna ring. We recommend mounting as described in
Chapter 5.4.1. If mounting in accordance with Chapter 5.4.1 is not possible,
(e.g. in the case of subsequent stator replacement), you will have to dismantle
the antenna ring. It is essential in this case to comply with the notes on assem
bling the antenna segments (see Chapter 5.4.2).

5.5 Preparing for the rotor mounting
CAUTION
The rotor is very heavy (depending on measuring range: 18kg … 39kg)!
Use a crane or other suitable lifting equipment to lift it out of its packaging and
install it.
Two eye bolts are screwed into the rotor as transport and mounting aids. Hook
the lifting equipment to these eye bolts as this ensures that the rotor is lifted
horizontally out of the packaging (see Fig. 5.1).
Transport and mounting eye bolts
Fig. 5.1 Transport and mounting eye bolts on the rotor
1. Lift the rotor out of the packaging, rotate horizontally by 180_, so that flange
B is pointing upwards (see Fig. 5.1).

Mechanical installation
Fig. 5.3 Rotor installation (horizontal)
4. Clean the plane faces of the transducer flange and the counter flange.
For safe torque transfer, the faces must be clean and free from grease. Use
a piece of cloth or paper soaked in solvent. Make sure that no solvent drips
into the inside of the transducer and that the transmitter coils are not dam
aged during cleaning.
5. Fasten the lifting equipment to the mounting eye bolt(s).
6. Carefully lift up the rotor and move it to the mounting position (see Fig. 5.1).
22 A3276-11.0 HBM: public T40FM
Mechanical installation
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 compon
ents. 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.
Notice
Make sure during installation that you do not damage the measuring zone
marked in Fig. 5.4 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 faces 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.

on the connection geometry, see Tab. 5.1 on Page 25).
We recommend fillisterhead screws DIN EN ISO 4762, blackened, smooth
headed, permitted size and shape variance in accordance with DIN ISO
4759, Part 1, product class A.
3. Fasten all screws with the specified torque (Tab. 5.1 on Page 25).
4. Now remove the eye bolt(s) used for transportation and mounting.
Important
Keep them in a safe place for future dismounting.
24 A3276-11.0 HBM: public T40FM

5. There are relevant tapped holes on flange B for continuing the shaft train
mounting. Again use screws of property class 10.9 and tighten them with
the prescribed torque, as specified in Tab. 5.1, Page 25.
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 screw-in depth as per Tab. 5.1, Page 25. Otherwise
significant measurement errors may result from torque shunt, or the transducer
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 mo
ments.
The required tightening moments 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
friction factor.
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 mounting.

1. Undo and remove the bolted connections (M5) on the upper antenna seg
ment.
There are fan-type lock washers 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 bolts yet.
3. Now use two hexagon socket screws to mount the upper antenna segment
removed in Point 1 on the lower antenna segment.
Make sure that the two fan-type lock washers are inserted between the an
tenna segments (these ensure that there is a defined contact resistance)!
Important
To make sure 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.

6. Now fully tighten the bolted stator housing connection.
Prevention of axial stator oscillation
Depending on the operating conditions, the stator may be induced to oscillate.
This effect is dependent on:
S the rotational speed,
S the antenna diameter (depends in turn on the measuring range),
S the design of the machine base.
Important
To prevent this axial oscillation, the antenna ring requires additional support by
the customer. There is a socket (with an M5 internal thread) on the upper an
tenna segment, which can be used for a suitable clamping device (see
Fig. 5.8). If this is the case, the cable plug also needs some support, as shown
in the construction example in Fig. 5.9.
