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 … 15kHz; Option HU2: 240 … 360kHz). 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).

2. Place the rotor carefully onto a clean and stable table.

3. If the rotor is to be installed horizontally as shown in Fig. 5.3, remove one
mounting eye bolt. Both mounting eye bolts can initially remain in the flange
for vertical installation.

T40FM A3276-11.0 HBM: public 21

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.

2. For the connection of flange A (see Fig. 5.4), use DIN EN ISO 4762
property class 10.9 hexagon socket screws of a suitable length (dependent
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.

T40FM A3276-11.0 HBM: public 27

Mechanical installation

Fig. 5.7 Alignment of the rotor with the stator

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.

Notice

The two (M4) screws are only used to fix the rotational speed disc. The meas
urement flange and the attached speed measuring system may therefore be
rotated only after mounting.

30 A3276-11.0 HBM: public T40FM

Mechanical installation

Important

The speed measuring system uses a magnetic measuring principle. In applica
tions where high magnetic field strengths can occur, e.g. eddy-current brakes,
implement suitable measures to ensure that the maximum permissibly mag
netic field strength cannot be exceeded (see Chapter 14 "Specifications",
Page 63).

Stator alignment (rotational speed measuring system, optionally with
reference signal)

The rotational speed measuring system is correctly aligned when the stator is
precisely aligned for torque measurement. A reduction in the distance between
the sensor head and magnetic ring can in some cases improve the signal qual
ity when the rotor is centrally positioned in the stator. To do this, loosen both
screws on the sensor head and push the sensor head in parallel as marked
with the arrows in Fig. 5.11.

The sensor for recording the reference signal is permanently set and must not
be adjusted.

6 Electrical Connection

6.1 General information

S With extension cables, make sure that there is a proper connection with

minimum contact resistance and good insulation.

S All cable connectors or swivel nuts must be fully tightened.

Important

Transducer connection cables from HBM with plugs attached are identified in
accordance with their intended purpose (Md or n). When cables are shortened,
inserted into cable ducts or installed in control cabinets, this identification can
get lost or become concealed. So the cables must be marked beforehand, just
in case.

6.2 EMC protection

Important

The transducers are EMC-tested in accordance with EC directives and identi
fied by CE certification. However, you must connect the shield of the connec
tion cable on the shielding electronics enclosure in order to achieve EMC pro
tection for the measuring chain.

Special electronic coding methods are used to protect the purely digital signal
transmission between the transmitter head and the rotor from electromagnetic
interference.

The cable shield is connected with the transducer housing. This encloses the
measurement system (without the rotor) in a Faraday cage when the shield is
laid flat at both ends of the cable. With other connection techniques, an
EMCproof shield should be applied in the wire area, and this shielding should

T40FM A3276-11.0 HBM: public 33

Electrical Connection

also be connected extensively (also see HBM Greenline Information, brochure
i1577).

Electrical and magnetic fields often induce interference voltages in the measur
ing circuit. Therefore:

S Use shielded, low-capacitance measurement cables only (HBM cables fulfill

both conditions).

S Only use plugs that meet EMC guidelines.

S Do not route the measurement cables parallel to power lines and control

circuits. If this is not possible, protect the measurement cable with e.g. steel
conduit.

S Avoid stray fields from transformers, motors and contact switches.

S Do not ground the transducer, amplifier and indicator more than once.

S Connect all the devices in the measuring chain to the same protective earth

conductor.

S In the case of interference due to potential differences (compensating cur

rents), the connections between supply voltage zero and housing ground
must be broken at the amplifier and a potential equalization line established
between the stator housing and the amplifier housing (copper conductor, at
least 10 mm

wire crosssection).

S Should differences in potential between the machine rotor and stator, be

cause of unchecked leakage, for example, cause interference, this can usu
ally be overcome by connecting the rotor definitively to ground, e.g. with a
wire loop. The stator must be connected to the same (ground) potential.

6.3 Pin Assignment

The stator housing has two 7-pin plugs, an 8-pin plug and a 16-pin plug.

The supply voltage connections and shunt signal connections of plugs 1 and 3
are each electrically interconnected, but are protected against compensating
currents by diodes. There is also a self-resetting fuse (multifuse) to protect the
supply voltage connections against overload by the stator.

Electrical Connection

The information in this Chapter relates to the self-contained operation of the
T40FM without HBM system solutions.

The supply voltage is electrically isolated from signal outputs and shunt signal
inputs. Connect a separated extra-low voltage of 18 V … 30 V to pin 3 (+) and
pin 2 (

KAB 8/00-2/2/2 and the appropriate sockets (see Accessories). The cable can
be up to 50m long for voltages ≥24V, otherwise it can be up to 20m long.

If the permissible cable length is exceeded, you can feed the supply voltage in
parallel over two connection cables (plugs 1 and 3). This enables you to double
the permissible length. Alternatively, install an on-site power supply.

The instant you switch on, a current of up to 4 A may flow and this may switch
off power packs with electronic current limiters.

Shunt signal

7 Shunt signal

The T40FM torque flange delivers an electrical shunt signal that can be activ
ated from the amplifier for measuring chains with HBM components. The trans
ducer generates a shunt signal of about 50% of the nominal (rated) torque; the
precise value is specified on the type plate. After activation, adjust the amplifier
output signal to the shunt signal supplied by the connected transducer, to adapt
the amplifier to the transducer.

Information

The transducer should not be under load when the shunt signal is being meas
ured, as the shunt signal is mixed additively.

Triggering the shunt signal

Applying a separated extra-low voltage of 5 … 30 V to pins 6 (+) and 7 (
plug 1 or 3, triggers the shunt signal.

The nominal (rated) voltage for triggering the shunt signal is 5 V (triggering at U
> 2.5 V), but when voltages are less than 0.7 V, the transducer is in measuring
mode. The maximum permissible voltage is 30 V, current consumption at nom
inal (rated) voltage is approx. 2 mA and at maximum voltage, approx. 18 mA.
The voltage for triggering the shunt signal is electrically isolated from the supply
and measuring voltage.

Tip

The shunt signal can be triggered by the amplifier or via the operating software
in HBM system solutions.

Bestimmungsgemäße Verwendung

Der Drehmoment‐Messflansch T40FM ist für Drehmoment‐, Drehwinkel‐ und
Leistungs‐Messaufgaben im Rahmen der durch die technischen Daten spezifi
zierten Belastungsgrenzen konzipiert. Jeder andere Gebrauch ist nicht bestim
mungsgemäß.

Der Betrieb des Stators ist nur mit montiertem Rotor zulässig.

Der Drehmoment‐Messflansch darf nur von qualifiziertem Personal ausschließ
lich entsprechend der technischen Daten unter Beachtung der Sicherheitsbe
stimmungen und Vorschriften dieser Montageanleitung eingesetzt werden.
Zusätzlich sind die für den jeweiligen Anwendungsfall geltenden Rechts‐ und
Sicherheitsvorschriften zu beachten. Sinngemäß gilt dies auch bei der
Verwendung von Zubehör.

6 A3276-11.0 HBM: public T40FM

Sicherheitshinweise

Der Drehmoment‐Messflansch ist nicht zum Einsatz als Sicherheitsbauteil
bestimmt. Bitte beachten Sie hierzu den Abschnitt „Zusätzliche Sicherheitsvor
kehrungen“. Der einwandfreie und sichere Betrieb setzt sachgemäßen
Transport, fachgerechte Lagerung, Aufstellung und Montage sowie sorgfältige
Bedienung voraus.

Belastbarkeitsgrenzen

Beim Einsatz des Drehmoment‐Messflanschs sind die Angaben in den
technischen Datenblättern unbedingt zu beachten. Insbesondere dürfen die
jeweils angegebenen Maximalbelastungen keinesfalls überschritten werden.
Nicht überschritten werden dürfen z.B. die in den technischen Daten angege
benen Werte für

S Grenzdrehmoment,

S Grenzlängskraft, Grenzquerkraft oder Grenzbiegemoment,

S Schwingbreite des Drehmoments,

S Bruchdrehmoment,

S Temperaturgrenzen,

S die Grenzen der elektrischen Belastbarkeit.

Einsatz als Maschinenelemente

Der Drehmoment‐Messflansch kann als Maschinenelemente eingesetzt
werden. Bei dieser Verwendung ist zu beachten, dass der Aufnehmer zu
Gunsten einer hohen Messempfindlichkeit nicht mit den im Maschinenbau übli
chen Sicherheitsfaktoren konstruiert wurde. Beachten Sie hierzu den Abschnitt
„Belastbarkeitsgrenzen“ und die technischen Daten.

Unfallverhütung

Entsprechend den einschlägigen Unfallverhütungsvorschriften der Berufsge
nossenschaften ist nach der Montage des Aufnehmers vom Betreiber eine Ab
deckung oder Verkleidung wie folgt anzubringen:

S Abdeckung oder Verkleidung dürfen nicht mitrotieren.

T40FM A3276-11.0 HBM: public 7

Sicherheitshinweise

S Abdeckung oder Verkleidung sollen sowohl Quetsch‐ und Scherstellen

vermeiden als auch vor evtl. sich lösenden Teilen schützen.

S Abdeckungen und Verkleidungen müssen weit genug von den bewegten

Teilen entfernt oder so beschaffen sein, dass man nicht hindurchgreifen
kann.

S Abdeckungen und Verkleidungen müssen auch angebracht sein, wenn die

bewegten Teile des Drehmoment‐Messflanschs außerhalb des Verkehrs‐
und Arbeitsbereiches von Personen installiert sind.

Von den vorstehenden Forderungen darf nur abgewichen werden, wenn der
Drehmoment‐Messflansch schon durch den Aufbau der Maschine oder bereits
vorhandene Schutzvorkehrungen ausreichend gesichert ist.

Zusätzliche Sicherheitsvorkehrungen

Der Drehmoment‐Messflansch kann (als passiver Aufnehmer) keine
(sicherheitsrelevanten) Abschaltungen vornehmen. Dafür bedarf es weiterer
Komponenten und konstruktiver Vorkehrungen, für die der Errichter und
Betreiber der Anlage Sorge zu tragen hat. Die das Messsignal verarbeitende
Elektronik ist so zu gestalten, dass bei Ausfall des Messsignals keine Folge
schäden auftreten können.

Der Leistungs‐ und Lieferumfang des Aufnehmers deckt nur einen Teilbereich
der Drehmoment‐Messtechnik ab. Sicherheitstechnische Belange sind vom
Anlagenplaner/Ausrüster/Betreiber so zu planen, zu realisieren und zu verant
worten, dass Restgefahren minimiert werden. Die jeweils existierenden natio
nalen und örtlichen Vorschriften sind zu beachten.

Allgemeine Gefahren bei Nichtbeachten der Sicherheitshinweise

Der Drehmoment‐Messflansch entspricht dem Stand der Technik und ist
betriebssicher. Von dem Aufnehmer können Gefahren ausgehen, wenn er von

(Unfallverhütungsvorschriften der BG) beim Umgang mit dem Aufnehmer, kann
der Aufnehmer beschädigt oder zerstört werden. Insbesondere bei Überlas
tungen kann es zum Bruch des Aufnehmers kommen. Durch den Bruch können
darüber hinaus Sachen oder Personen in der Umgebung des Aufnehmers zu
Schaden kommen.

Wird der Drehmoment‐Messflansch nicht seiner Bestimmung gemäß eingesetzt
oder werden die Sicherheitshinweise oder die Vorgaben der Montage‐ oder
Bedienungsanleitung außer Acht gelassen, kann es ferner zum Ausfall oder zu
Fehlfunktionen des Aufnehmers kommen, mit der Folge, dass (durch auf den
Drehmoment‐Messflansch einwirkende oder durch diesen überwachte Dreh
momente) Menschen oder Sachen zu Schaden kommen können.

Umbauten und Veränderungen

Der Aufnehmer darf ohne unsere ausdrückliche Zustimmung weder konstruktiv
noch sicherheitstechnisch verändert werden. Jede Veränderung schließt eine

Aufbau und Wirkungsweise

4 Aufbau und Wirkungsweise

Der Drehmoment‐Messflansch besteht aus zwei getrennten Teilen, dem Rotor
und dem Stator. Der Rotor setzt sich zusammen aus dem Messkörper und den
Signal‐Übertragungselementen.

Auf dem Messkörper sind Dehnungsmessstreifen (DMS) installiert. Die Rotor
elektronik für die Brückenspeisespannungs‐ und Messsignalübertragung ist
zentrisch im Flansch angeordnet. Der Messkörper trägt am äußeren Umfang
die Übertragerspulen für die berührungslose Übertragung von Speisespannung
und Messsignal. Die Signale werden von einem teilbaren Antennenring gesen
det bzw. empfangen. Der Antennenring ist auf einem Gehäuse befestigt, in
dem die Elektronik für die Spannungsanpassung sowie die Signalaufbereitung
untergebracht sind.

Am Stator befinden sich Anschlussstecker für das Drehmoment‐ und das Dreh
zahlsignal, die Spannungsversorgung und den digitalen Ausgang. Die Anten
nensegmente (der Antennenring) müssen konzentrisch um den Rotor montiert
werden (siehe Kapitel 5).

5.1 Wichtige Vorkehrungen beim Einbau

Hinweis

Ein Drehmoment‐Messflansch ist ein Präzisions‐Messelement und verlangt
daher eine umsichtige Handhabung. Stöße oder Stürze können zu
permanenten Schäden am Aufnehmer führen. Sorgen Sie dafür, dass auch bei
der Montage keine Überlastung des Aufnehmers auftreten kann.

S Behandeln Sie den Aufnehmer schonend.

S Prüfen Sie den Einfluss von Biegemomenten, kritischen Drehzahlen und

Torsionseigenschwingungen, um eine Überlastung des Aufnehmers durch
Resonanzüberhöhungen zu vermeiden.

S Stellen Sie sicher, dass der Aufnehmer nicht überlastet werden kann.

WARNUNG

Bei einer Überlastung des Aufnehmers besteht die Gefahr, dass der Auf
nehmer bricht. Dadurch können Gefahren für das Bedienpersonal der Anlage
auftreten, in die der Aufnehmer eingebaut ist.

Treffen Sie geeignete Sicherungsmaßnahmen zur Vermeidung einer Überlas
tung und zur Sicherung gegen sich daraus ergebende Gefahren.

S Kleben Sie die Verbindungsschrauben mit einer Schraubensicherung (mit

telfest, z.B. von LOCTITE) in das Gegengewinde ein, um einen Vorspann
verlust durch Lockern auszuschließen, falls Wechsellasten zu erwarten
sind.

S Halten Sie die Montagemaße unbedingt ein, um einen einwandfreien

Betrieb zu ermöglichen.

Mechanischer Einbau

Der Drehmoment‐Messflansch T40FM kann über einen entsprechenden Wel
lenflansch direkt montiert werden. Am Rotor ist auch die direkte Montage einer
Gelenkwelle oder entsprechender Ausgleichselemente (bei Bedarf über Zwi
schenflansch) möglich. Die zulässigen Grenzen für Biegemomente, Quer‐ und
Längskräfte dürfen jedoch in keinem Fall überschritten werden. Durch die hohe
Drehsteifigkeit des Aufnehmers T40FM werden dynamische Veränderungen
des Wellenstrangs gering gehalten.

Wichtig

Auch bei korrektem Einbau kann sich der im Werk abgeglichene Nullpunkt bis
zu ca. 0,5% vom Kennwert verschieben. Wird dieser Wert überschritten, emp
fehlen wir, die Einbausituation zu prüfen. Ist der bleibende Nullpunktversatz im
ausgebauten Zustand größer als 1% vom Kennwert, senden Sie den Aufneh
mer bitte zur Prüfung ins Werk Darmstadt.

5.2 Bedingungen am Einbauort

Der Drehmoment‐Messflansch T40FM muss vor grobem Schmutz, Staub, Öl,
Lösungsmitteln und Feuchtigkeit geschützt werden.

Der Aufnehmer ist in weiten Grenzen gegen Temperatureinflüsse auf das Aus
gangs‐ und Nullsignal kompensiert (siehe Kapitel 14 „Technische Daten“).
Liegen keine stationären Temperaturverhältnisse vor, z.B. durch Temperatur
unterschiede zwischen Messkörper und Flansch, können die in den techni
schen Daten spezifizierten Werte überschritten werden. Sorgen Sie in diesen
Fällen je nach Anwendungsfall durch Kühlung oder Heizung für stationäre
Temperaturverhältnisse. Prüfen Sie alternativ, ob eine Temperaturentkopplung
möglich ist, z.B. durch Wärme abstrahlende Elemente wie Lamellenkupplun
gen.

5.3 Einbaulage

Die Einbaulage des Drehmoment‐Messflanschs ist beliebig.

T40FM A3276-11.0 HBM: public 17

Mechanischer Einbau

Bei Rechtsdrehmoment (im Uhrzeigersinn) beträgt die Ausgangsfrequenz bei
Option 5, Code DU2 60 … 90 kHz (Option 5, Code SU2: 10 … 15kHz; Option
HU2: 240 … 360kHz). In Verbindung mit Messverstärkern von HBM oder bei
Nutzung des Spannungsausgangs steht ein positives Ausgangssignal (0 V …
+10 V) an. Beim Drehzahl‐Messsystem ist zum eindeutigen Bestimmen der
Drehrichtung auf dem Statorgehäuse ein Pfeil angebracht: Dreht der Mess
flansch in Pfeilrichtung, liefern angeschlossene HBM‐Messverstärker ein posi
tives Ausgangssignal.

5.4 Einbaumöglichkeiten

Prinzipiell haben Sie zwei Möglichkeiten, den Drehmoment‐Messflansch zu
montieren: mit oder ohne Zerlegen des Antennenringes. Wir empfehlen die
Montage nach Kapitel 5.4.1. Ist eine Montage nach Kapitel 5.4.1 nicht möglich
(z.B. bei nachträglichem Wechsel des Stators), müssen Sie den Antennenring
zerlegen. Beachten Sie hierbei unbedingt die Hinweise zum Zusammenbau der
Antennensegmente (siehe Kapitel 5.4.2).

5.6 Montage des Rotors

Tipp

Nach der Montage ist in der Regel das Rotor‐Typenschild verdeckt. Deshalb
liegen dem Rotor zusätzliche Klebeschilder mit den wichtigen Kenndaten bei,
die Sie auf den Stator oder andere relevante Prüfstandskomponenten auf
kleben können. Sie können dann jederzeit die für Sie interessanten Daten
ablesen, z.B. das Shuntsignal. Für die eindeutige Zuordnung der Daten ist am
Rotorflansch von außen sichtbar eine Identifikationsnummer und die Baugröße
eingraviert.

Hinweis

Achten Sie darauf, dass während der Montage die in Abb. 5.4 markierte Mess
zone nicht beschädigt wird, z.B. durch Abstützen oder Anschlagen von Werk
zeugen beim Anziehen der Schrauben. Dies kann den Aufnehmer beschädigen
und damit zu Fehlmessungen führen oder sogar zerstören.

1. Reinigen Sie vor dem Einbau die Flanschplanflächen des Aufnehmers und
der Gegenflansche.

Die Flächen müssen für eine sichere Drehmomentübertragung sauber und
fettfrei sein. Benutzen Sie mit Lösungsmittel angefeuchtete Lappen oder
Papier. Achten Sie beim Reinigen darauf, dass die Übertragerwicklung nicht
beschädigt wird.
