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, forexample, must
not be exceeded for
SLimit torque,
SLongitudinal limit force, lateral limit force or bending limit moment,
STorque oscillation width,

Safety instructions
T40FH A4429-3.0 HBM: public 7
SBreaking torque,
STemperature limits,
SLimits 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:
SThe covering agent or cladding must not be free to rotate.
SThe covering agent or cladding should prevent squeezing or shearing and
provide protection against parts that might come loose.
SCovering agents and cladding must be positioned at a suitable distance or
be so arranged that there is no access to any moving parts within.
SCovering 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.

Safety instructions
8A4429-3.0 HBM: public T40FH
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
12 A4429-3.0 HBM: public T40FH
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.

Structure and mode of operation
T40FH A4429-3.0 HBM: public 13
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).

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 Mechanical installation
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.
SHandle the transducer with care.
SCheck the effect of bending moments, critical rotational speeds and natural
torsional vibrations, to prevent the transducer being overloaded by reso
nance sharpness.
SMake 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.
SUse 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.
SComply 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

Mechanical installation
16 A4429-3.0 HBM: public T40FH
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 …15kHz; Option HU2: 240 …360kHz). 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.

Mechanical installation
T40FH A4429-3.0 HBM: public 17
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).
