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

Safety information
T40FM A3276-11.0 HBM: public 7
be exceeded. For example, the values stated in the specifications must not be
exceeded, e.g. for
SLimit torque
SLongitudinal limit force, lateral limit force or limit bending moment
STorque oscillation width
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 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:
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 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.

Safety information
8A3276-11.0 HBM: public T40FM
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
12 A3276-11.0 HBM: public T40FM
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.

Structure and Mode of Operation
T40FM A3276-11.0 HBM: public 13
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.
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 reson
ance 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 in
stalled.
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.

Mechanical installation
16 A3276-11.0 HBM: public T40FM
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

Mechanical installation
T40FM A3276-11.0 HBM: public 17
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).
