Intended use
The T40MS 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 the intended use.
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 installation
instructions. The applicable legal and safety regulations for the specific type of use
must be observed. The same applies to the use of accessories.
The torque flange is not intended for use as a safety component. Please refer to the
“Additional safety precautions” section. Proper and safe operation requires proper
transportation, correct storage, siting and installation, 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.
For example, the values stated in the specifications must not be exceeded for
STorque limit
SAxial limit force, lateral limit force or bending moment limit
STorque oscillation width
SBreaking torque
STemperature limits
SLimits of electrical load-carrying capacity.
Use as machine elements
The torque flange can be used as a machine element. When used in this manner,
please note that, in the interest of greater sensitivity, the transducer is not designed
with the safety factors usual in mechanical engineering. Please refer to the “Load-
carrying capacity limits” section and the specifications.
Accident prevention
According to the prevailing accident prevention regulations, once the transducer has
been installed, the plant operator must fit a covering agent or cladding as follows:
SThe covering agent or cladding must not rotate.
SThe covering agent or cladding must prevent crushing and shearing and provide
protection against parts that might become detached.
SCovering agents and cladding must be positioned at a suitable distance from moving
parts or designed so as to prevent access.
SCovering agents and cladding must remain attached even if the moving parts of the
torque flange are installed outside the movement and operating range of persons.
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 safeguards.
Additional safety precautions
As a passive transducer, the torque flange cannot perform (safety-relevant) shutdowns.
This requires additional components and design measures, for which the installer and
operator of the plant is responsible. The electronics that process the measurement signal
should be designed so that failure of the measurement signal cannot lead to secondary
failures.
The scope of supply and performance of the transducer covers only a small area of
torque measurement technology. Equipment planners, installers and operators should
plan, implement and respond to safety engineering considerations in such a way as to
minimize residual dangers. Pertinent national and local regulations must be complied
with.

SAFETY INSTRUCTIONS
General risks if the safety instructions are not complied with
The torque flange corresponds to the state of the art and is safe to operate. Transducers
can give rise to residual risks if they are incorrectly operated or inappropriately installed,
configured, used and operated by untrained personnel. Every person involved with siting,
starting up, operating or repairing a torque flange must have read and understood the
installation instructions and the technical safety instructions, in particular. The transducer
can be damaged or destroyed by improper use of the transducer or by non-compliance
with the installation and operating instructions, these safety instructions or any other
applicable safety regulations during its use. Transducers can break, particularly if they
are overloaded. The breakage of a transducer can also damage property or injure
persons in the vicinity of the transducer.
If the torque flange is not used as intended, or if the safety instructions or specifications
in the installation and operating instructions are ignored, the transducer may fail or
malfunction, with consequences for persons or property (due to the torques acting on or
being monitored by the torque flange).

APPLICATION
10
3 APPLICATION
The T40MS torque flange measures static and dynamic torques on stationary and
rotating shafts. Test beds can be extremely compact because of the compact design of
the transducer. This offers a very wide range of applications.
The T40MS torque flange is reliably protected against electromagnetic interference. It
has been tested in accordance with harmonized European standards and/or complies
with US and Canadian standards. The product bears the CE mark and/or FCC label.

T40MS
DESIGN AND MODE OF OPERATION
4 DESIGN AND MODE OF OPERATION
The torque flange consist of two separate parts: the rotor and the stator. The rotor
consists of 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 the measurement signal are located on the measuring body's outer
circumference. The signals are sent and received by a segmented antenna ring.
The antenna ring is mounted on a housing that contains the electronic system for
voltage adaptation and signal conditioning.
Connectors for the torque and rotational speed signals, the voltage supply and the
digital output are located on the stator. The antenna segments (of the antenna ring)
must be mounted concentrically around the rotor (see section 5).

5.1 Important precautions during installation
Notice
A torque flange is a precision measurement element and therefore needs careful handling.
Dropping or knocking the transducer may cause permanent damage. Take care to avoid
overloading the transducer, including during installation.
uHandle the transducer with care.
uCheck the effect of bending moments, critical rotational speeds and natural torsional
vibrations, to prevent transducer overload due to increases in resonance.
uMake sure that the transducer cannot be overloaded.
WARNING
If the transducer is overloaded, there is a risk that it might break. This can cause danger to
the operating personnel of the system in which the transducer is installed.
Implement appropriate safety measures to prevent overloading and to safeguard against
resulting risks.
uUse threadlocker (medium strength, e.g., LOCTITE) to glue the screws into the counter
thread to exclude prestressing loss due to screws slackening if alternating loads are
expected.
uTo ensure problem-free operation, compliance with the installation dimensions is
essential.
A suitable shaft flange enables the T40MS torque flange to be mounted directly. A joint
shaft or suitable compensating element can also be mounted directly on the rotor (using
an intermediate flange if required). However, the permitted limits for bending moments,
lateral and longitudinal forces must not be exceeded under any circumstances. Due to
the T40MS torque flange's high torsional stiffness, dynamic shaft train changes are kept
to a minimum.
Important
Even if the device is installed correctly, the zero point adjustment made at the factory can
shift by up to approx. 2% of the characteristic value. If this value is exceeded, we
recommend checking the installation conditions. If the residual zero drift when the device
is removed is greater than 1% of the characteristic value, please send the transducer back
to the Darmstadt factory for testing.

5.2 Conditions at the installation site
The T40MS 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 output and
zero signals of the transducer (see “Specifications” section). If temperature conditions
are not static due to temperature differences between the measuring body and the
flange, for example, the values given in the specifications can be exceeded. In this case,
ensure static temperature conditions by cooling or heating, depending on the type of use.
Alternatively, check if thermal decoupling is possible, e.g., by means of heat radiating
elements such as multiple-disk couplings.
5.3 Installation position
The torque flange can be installed 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 conjunction with HBM
amplifiers or when using the voltage output option, a positive output signal (0 V …+10 V)
is present. In a device with rotational speed measuring system, an arrow on the stator
housing clearly indicates the direction of rotation: If the measurement flange moves in
the direction of the arrow, connected HBM measuring amplifiers deliver a positive output
signal.
5.4 Installation options
There are basically two options for installing the torque flange: with the antenna ring
complete or dismantled. We recommend performing installation as described in section
5.4.1. If installation as per section 5.4.1 is not possible (e.g., if subsequently replacing the
stator), you will have to dismantle the antenna ring. In this case, it is essential that you
comply with the instructions for assembling the antenna segments (see section 5.4.2).

5.5 Installing the rotor
Tip
The rotor type plate is generally no longer visible after installation. The rotor therefore
comes supplied with additional stickers bearing the main characteristics, which you can
attach to the stator or any other relevant test-bench components. You can then refer to
them whenever there is anything you wish to know, such as the shunt signal. To make the
information extremely clear, the identification number and size are engraved on the rotor
flange, where they can be seen from the outside.
Notice
During installation, make sure that you do not damage the measuring zone marked in
Fig. 5.1, for example by using it to support tools or knocking tools against it when
tightening screws. This can damage the transducer and produce measurement errors,
or even irreparably damage the transducer.

uBefore installation, clean the plane faces of the transducer flange and the counter
flanges.
The faces must be clean and free from grease to ensure safe torque transfer. Use a
piece of cloth or paper soaked in solvent. When cleaning, take care not to damage the
transmitter winding or rotational speed measuring system.
