NOTE
Any changes or modification not expressly approved by the party responsible
for compliance could void the user’s authority to operate the device. Where
specified additional components or accessories elsewhere defined to be used
with the installation of the product, they must be used in order to ensure compliance with FCC regulations.
Appropriate use
The T12 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. In particular, the respective maximum loads specified must
never be exceeded. For example, the values stated in the specifications must
not be exceeded for
 limit torque,
 longitudinal limit force, lateral limit force or limit bending moment,
 torque oscillation width,
 breaking torque,
 temperature limits,
 the limits of the electrical load-carrying capacity.

T12
Use as a machine element
The torque flange can be used as a machine element. When used in this
manner, 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
transducers have been mounted, a covering agent or cladding has to be fitted
as follows:
 The covering agent or cladding must not be free to rotate.
 The covering agent or cladding should prevent squeezing or shearing and
provide protection against parts that might come loose.
 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.
 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.
Additional safety precautions
The torque flange cannot (as a passive transducer) implement any
(safety-relevant) 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,
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.
General dangers of failing to follow the safety instructions
The torque flange corresponds to the state of the art and is reliable.
Transducers can give rise to residual dangers if they are incorrectly operated
or inappropriately 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 technical safety instructions. The transducers can be damaged
A1979−10.0 en
HBM
8
T12
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 adversely affected (due to the
torques acting on or being monitored by the torque flange).
Conversions and modifications
The transducer must not be modified from the design or safety engineering
point of view except with our express agreement. 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.
Qualified personnel
Qualified personnel means persons entrusted with siting, mounting, starting
up and operating the product, who possess the appropriate qualifications for
their function.
This includes people who meet at least one of the three following
requirements:
− Knowledge of the safety concepts of automation technology is a
requirement and as project personnel, you must be familiar with these
concepts.
− As automation plant operating personnel, you have been instructed how to
handle the machinery. You are familiar with the operation of the equipment
and technologies described in this documentation.
− As system startup engineers or service engineers, you have successfully

Application
The T12 digital torque transducer acquires static and dynamic torque at
stationary or rotating shafts, determines the rotational speed or angle of
rotation while specifying the direction of rotation, and calculates the power. It
is designed for:
 highly dynamic torque measurements when testing the power and
functionality of engines and compound sets
 high-resolution rotational speed and angle of rotation measurements
 fast, dynamic power measurements on engine and transmission test rigs
and roll test stands
Designed to work without bearings and with contactless digital signal
transmission, the torque measuring system is maintenance-free.
The torque transducer is supplied for nominal (rated) torques of 100 Nm to
10 kNm. Depending on the nominal (rated) torque, maximum rotational
speeds of up to 18 000 rpm are permissible.
The T12 torque transducer is reliably protected against electromagnetic
interference. It has been tested according to harmonized European standards
and complies with US and Canadian standards. The product carries the CE
mark and / or FCC label.

The torque signal can be zeroed
filtered via two low passes (LP1 and LP2). A further scaling of the frequency
output and the analog output is then possible.
Important
Scaling at position  (see Fig. 4.1) changes the internal calibration of the
torque transducer.
The rotational speed signal can be filtered and also scaled for analog output.
The angle of rotation signal, the power signal (low-pass filter LP) and the
temperature signal are only available on fieldbuses.
The torque signal and the rotational speed signal can be filtered via two low
passes connected in series, with filter outputs also being available separately.
The scaled, unfiltered torque signal is used to calculate power. The resultant,
highly-dynamically calculated power signal is filtered via a further low pass.
A1979−10.0 en
HBM
14
T12
For settings over 100 Hz (torque low-pass filter 1 only), phase delay
compensation is run for the angle of rotation signal. This ensures that torque
and angle of rotation values that are measured simultaneously are also output
simultaneously.
Two pulse strings, offset by 90, are also available as RS422-compatible
signals for rotational speed and angle of rotation.
Structure and mode of operation
The torque transducer comprises two separate parts: the rotor and the stator.
Strain gages (SGs) are installed on the rotor for torque calculation.
Carrier-frequency technology (19.2 kHz carrier frequency) is used for the SG
evaluation. The rotor temperature is acquired at two measuring points and
averaged.
The electronics for transmitting the bridge excitation voltage and the
measurement signal are located centrally in the rotor. The coils for the
contactless transmission of excitation voltage and measurement signal are
located on the outer circumference of rotor side A. The signals are sent and
received by a transmitter head. The transmitter head is mounted on the stator,
which houses the electronics for voltage adaptation and signal conditioning.
Connector plugs for inputs and outputs (for pin assignment, see Chapter 9.3)
are located on the stator. The transmitter head encloses the rotor over a
segment of about 120 and should be mounted concentrically around the rotor
(see Chapter 7).
In the case of the rotational speed measuring system option, the rotational
speed sensor is mounted on the stator and the customer attaches the
associated slotted disc on the rotor. Rotational speed measurement is optical,
using the infrared transmitted light principle.

Mechanical installation
7.1 Important precautions during installation
NOTE
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.
 Handle the transducer with care.
 Check the effect of bending moments, critical rotational speeds and natural
torsional vibrations, to prevent the transducer being overloaded by
resonance sharpness.
 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 installed.
Implement appropriate safety measures to avoid overloads and to protect
against resulting dangers.
 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.
 Comply with the mounting dimensions to enable correct operation.
An appropriate shaft flange enables the T12 torque flange to be mounted
directly. It is also possible to mount a joint shaft or relevant compensating
element 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 T12 torque
flange’s high torsional stiffness, dynamic shaft train changes are kept to a
minimum.
HBM
A1979−10.0 en
17
T12
Important
Even if the unit is installed correctly, the zero point adjustment made at the
factory can shift by up to approx. 3% of the sensitivity. 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.
7.2 Conditions on site
The T12 torque transducer is protected to IP54 according to EN 60529.
Protect the transducer from coarse dirt, dust, oil, solvents and moisture.
During operation, the prevailing safety regulations for the security of
personnel must be observed (see “Safety instructions”).
There is wide ranging compensation for the effects of temperature on the
output and zero signals of the T12 torque transducer (see specifications on
page 56). This compensation is carried out at static temperatures. This
guarantees that the circumstances can be reproduced and the properties of
the transducer can be reconstructed at any time.
If there are no static temperature ratios, for example, because of the
temperature differences between flange A and flange B, the values given in
the specifications can be exceeded. Then for accurate measurements, you
must ensure static temperature ratios by cooling or heating, depending on the
application. As an alternative, check thermal decoupling, by means of heat
radiating elements such as multiple disc couplings.
7.3 Mounting position
The transducer can be mounted in any position. With clockwise torque, the
output frequency is 10 to 15 kHz (Option 4, code DF1/DU2: 60 kHz to
90 kHz). In conjunction with HBM amplifiers or when using the voltage output,
a positive output signal (0 V to +10 V) is present.
With counterclockwise torque, the output frequency is 5 kHz to 10 kHz (Option
4, code DF1/DU2: 30 kHz to 60 kHz).
In the case of the rotational speed measuring system, an arrow is attached to
the head of the sensor to clearly define the direction of rotation. When the
transducer rotates in the direction of the arrow, a positive rotational speed
signal is output.

7.4 Installing the slotted disc (rotational speed measuring
system only)
To prevent damage to the rotational speed measuring system’s slotted disc
during transportation, it is not mounted on the rotor. The customer must attach
it to the mounting ring before installing the rotor in the shaft train. The
mounting ring and the associated rotational speed sensor are already
mounted at the factory.
The requisite screws, a suitable screwdriver and the threadlocker are included
among the components supplied.

When carrying out the installation, be careful not to damage the slotted disc!
Installation sequence
1. Push the slotted disc onto the mounting ring and align the screw holes.
2. Apply some of the threadlocker to the screw thread and tighten the screws
(tightening torque < 0.15 Nm).

7.5 Installing 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
components. 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.
NOTE
Make sure during installation that you do not damage the measuring zone
marked in Fig. 6.2 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 coils.
2. For the flange B screw connection, use hexagon socket screws DIN EN
ISO 4762 of property class 10.9 (measuring ranges 3 kN@m to 10 kN@m:
12.9) of the appropriate length (depending on the connection geometry, see
Table 6.1).
We recommend fillister-head screws DIN EN ISO 4762, blackened,
smooth-headed, permitted size and shape variance as per DIN ISO 4759,
Part 1, product class A.
3. First tighten all the screws crosswise with 80% of the prescribed tightening
torque (Table 6.1), then tighten again crosswise, with the full tightening
torque.
4. There are relevant tapped holes on flange A for continuing the shaft train
mounting. Again use screws of property class 10.9 (measuring ranges
3 kNm to 10 kNVm: 12.9), and tighten them with the prescribed moment as
specified in Table 6.1.

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.

Dry screw connections can result in different friction factors (see VDI 2230, for
example). This means a change to the required tightening moments.
The required tightening moments can also change if you use screws with a
surface or property class other than that specified in Table 6.1, as this affects
the friction factor.
7.6 Fitting the protection against contact (option)
The protection against contact comprises two side parts and four cover plates.
It is screwed onto the stator housing.

7.7 Installing the stator
On delivery, the stator has already been installed and is ready for operation.
There are four tapped holes on the base of the stator housing for mounting
the stator. Externally, two with a metric M6 thread, internally, two with a UNF
1/4” thread (closed with a plastic threaded pin).
We recommend using two metric thread DIN EN ISO 4762 fillister-head
screws with hexagon sockets of property class 10.9 of the appropriate length
(depending on the connection geometry – not included among the
components supplied; tightening torque = 14 N@m).
Tip
To allow the stator to be aligned to the rotor, make sure that repositioning is
possible (e.g. oblong holes).
The stator can be mounted radially in any position (an “upside down”
installation is possible, for example). You can also install the stator over the
protection against contact (option), see Chapter 7.7.3 .
Fig. 6.11: Mounting holes in the stator housing (viewed from below)
With the T12/5 kN@m and T12/10 kN@m torque transducers, we recommend
additionally supporting the stator at the protection against contact. Fig. 6.12
shows an example of how to attach an angle bracket with a bolt (A) or with a
threaded rod (B). Note that in this case, the cover plates cannot be fitted.

The supplied mounting kit contains self-adhesive spacers, to make it easier
for you to align the stator to the rotor.

length or attach them slightly offset, next to the rotational speed measuring
system.

7.7.2 Aligning the stator
1. Position the stator on an appropriate mounting base in the shaft train, so
that there are sufficient opportunities for horizontal and vertical adjustments
to be made.
2. Should there be any misalignment in height, compensate for this by
inserting adjusting washers.
3. Only tighten the fastening screws by hand, initially.
4. Use the spacers to radially align the stator to the rotor.
5. Use the spacers to axially align the stator to the rotor. The rotor should be
in line with the edge of the red spacer, see Fig. 6.16.

system (option)
As the stator with the optical rotational speed sensor only partially encloses
the slotted disc, if there is sufficient space available for installation, you can
subsequently move the stator tangentially over the ready-mounted rotor.
For perfect measuring mode, the slotted disc of the rotational speed
measuring system must rotate at a defined position in the sensor pickup.
7.8.1 Axial alignment
There is a mark (orientation line) in the sensor pickup for axial alignment.
When installed, the slotted disc should be exactly above this orientation line.

Electrical connection
9.1 General information
Detailed instructions for connecting the T12 to the CAN Bus or the
PROFIBUS can be found in the “T12 CAN Bus/PROFIBUS” interface
description (in pdf format) on the T12 system CD.
To make the electrical connection between the torque transducer and the
measuring amplifier, we recommend using shielded, low-capacitance
measurement cables from HBM.
With extension cables, make sure that there is a proper connection with
minimum contact resistance and good insulation. All plug connections or
swivel nuts nuts must be fully tightened.
Do not route the measurement cables parallel to power lines and control
circuits. If this cannot be avoided (in cable pits, for example), maintain a
minimum distance of 50 cm and also draw the measurement cable into a steel
tube.
Avoid transformers, motors, contactors, thyristor controls and similar
stray-field sources.
Consider longer cable of approximately 40cm due to the installation of the
wounded core (toroidal core).
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. If this is the case, it is
essential for the cables to be re-labeled!
Tape wound core (toroidal core):
To suppress high frequencies a tape wound core (toroidal core) on the power
cable has to be used. Use at least 3 loops of the cable.
A1979−10.0 en
HBM
38
T12
3 loops
Fig. 6.21: Installation Example
If the core has to be removed for any purpose (e.g. for maintenance), it must
be replaced on the cable. Use only wounded core (toroidal core) of the correct
type.
Type: Vitroperm R
Model No.: T60006−22063W517
Size: external diameter x internal diameter x height = 63 x 50 x 25
The core should be placed as close as possible to the connector. However,
prevent stress on the connector due to the extra weight of the cable.
NOTE
For US stator Version Option 9, Code U the use of a tape wound core (toroidal core) on the power cable (plug 1 or plug3) is mandatory to ensure compliance with FCC regulations.

9.2 Shielding design
The cable shield is connected in accordance with the Greenline concept. This
encloses the measurement system (without the rotor) in a Faraday cage. It is
important that the shield is laid flat on the housing ground at both ends of the
cable. Any electromagnetic interference active here does not affect the
measurement signal. Special electronic coding methods are used to protect
the purely digital signal transmission between the transmitter head and the
rotor from electromagnetic interference.
In the case of interference due to potential differences (compensating
currents), supply voltage zero and housing ground must be disconnected on
the amplifier and a potential equalization line established between the stator
housing and the amplifier housing (copper conductor, 10 mm2 wire
crosssection).
Should differences in potential between the machine rotor and stator cause
interference, because of unchecked leakage, for example, this can usually be
overcome by connecting the rotor definitively to ground, by a wire loop, for
example. The stator should be fully grounded in the same way.

9.4 Supply voltage
The transducer must be operated with a separated extra-low voltage (nominal
(rated) supply voltage 18 to 30 VDC). You can supply one or more torque
flanges within a test bench at the same time. Should the device be operated
on a DC voltage network1), additional precautions must be taken to discharge
excess voltages.
The notes in this section relate to the self-contained operation of the T12
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 to 30 V to pin 3 (+) and
pin 2 ( ) of plug 1 or 3. We recommend that you use HBM cable
KAB 8/00−2/2/2 and the relevant Binder sockets, that at nominal (rated)
A1979−10.0 en
HBM
44
T12
voltage (24 V) can be up to 50 m long and in the nominal (rated) voltage
range, 20 m long (see Accessories, page 88).
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.
If you feed the supply voltage through an unshielded cable, the cable must be
twisted (interference suppression). We also recommend that a ferrite element
should be located close to the connector plug on the cable, and that the stator
should be grounded.
Important
The instant you switch on, a current of up to 4 A may flow and this may switch
off power supplies with electronic current limiters.

example) that may possibly also supply consumers with high nominal (rated) currents.

Shunt signal
The T12 torque transducer supplies a shunt signal, at either 50% or 10% of
the nominal (rated) torque, as selected. Activate this function via the T12
Assistant or the shunt signal trigger on plug 1 or plug 3 (see Section 9.3). The
last shunt selected in the T12 Assistant is then triggered.
The internal signal conditioning may cause a delay in triggering of about 5
seconds.
To obtain stable conditions, we recommend activating the shunt signal only
once the transducer has been warming up for 15 minutes.
The framework conditions for reproducibility (e.g. the mounting conditions)
must be established in order to reproduce the measured values in the
manufacturing certificate.
Important
The transducer should not be under load when the shunt signal is being
measured, as the signal is applied additively.
After about 5 minutes, the shunt signal is automatically deactivated.

Load-carrying capacity
Nominal (rated) torque can be exceeded statically up to the limit torque. If the
nominal (rated) torque is exceeded, additional irregular loading is not
permissible. This includes longitudinal forces, lateral forces and bending
moments. Limit values can be found in the “Specifications” chapter (Chapter
15, page 56).
Measuring dynamic torque
The torque transducer is suitable for measuring static and dynamic torques.
The following apply to the measurement of dynamic torque:
 The T12 calibration run for static measurements is also valid for dynamic
torque measurements.
 The natural frequency f0 of the mechanical measuring system depends on
the moments of inertia J1 and J2 of the connected rotating masses and the
T12’s torsional stiffness.
Use the equation below to approximately determine the natural frequency f0 of
the mechanical measuring system:

J1, J2 = mass moment of inertia in kgm2
cT
= torsional stiffness in Nm/rad
 The maximum oscillation width is 200% (measuring range 3 kN@m to 10
kN@m: 160%) of the typical nominal (rated) torque for the T12 (see
“Specifications”, page 56) The oscillation width must lie between the
maximum upper and lower torques of the defined loading range. The same
also applies to transient resonance points.

TEDS
TEDS (Transducer Electronic Data Sheet) allows you to store the transducer
data (characteristic values) in a chip, that can be read out by a connected
measuring instrument.
There are two TEDS blocks in the T12 digital torque transducer:
 TEDS 1 (torque): a choice of voltage sensor or frequency sensor/pulse
sensor
 TEDS 2 (rotational speed/angle of rotation): frequency sensor/pulse sensor
The data are written automatically into the TEDS blocks by the T12 Assistant,
when the parameters are stored. The same menu is used to select whether
the device should be presented as a voltage sensor or as a frequency sensor
or as a frequency or pulse sensor. A template is also stored, which provides
the conversion factors for the different physical units.
The T12 is a transducer, that is to say, the T12 does not read the TEDS
blocks, it only writes them. (We therefore strongly advise against editing the
values with the HBM TEDS Editor, for example!)
You can read the data of the TEDS block with the TEDS Editor.
Important
To ensure that the data of the TEDS blocks correspond to the properties of
the T12 torque transducer, you must not overwrite the information from the
measuring amplifier.
For more information on TEDS, look in the T12 Assistant online Help.
Content of the TEDS memory as defined in IEEE 1451.4
The information in the TEDS memory is organized into areas, which
are prestructured to store defined groups of data in table form.
Only the entered values are stored in the TEDS memory itself. The amplifier
firmware assigns the interpretation of the respective numerical values. This
places a very low demand on the TEDS memory. The memory content is
divided into three areas:
Area 1:
An internationally unique TEDS identification number (cannot be changed).

Maintenance
The T12 torque transducer without a rotational speed measuring system is
maintenance-free.
Cleaning the rotational speed measuring system
During operation and depending on the ambient conditions, the slotted disc of
the rotor and the associated optical system of the stator sensor can get dirty.
This becomes noticeable, for example:
 in transducers with a reference pulse, when an increment error is displayed
in the “Rotational speed signal” status in the T12 Assistant.
 in transducers without a reference pulse, when there are cyclic intrusions
into the rotational speed signal.
Remedy:
1. Use compressed air (up to 6 bar) to clean the slotted disc.
2. Carefully clean the optical system of the sensor with a dry cotton bud or
one soaked with pure spirit.
NOTE
Do not use any other solvent to clean the optical system of the sensor! It
could alter the optical properties (make plastic cloudy).

condition is not met, the limit values must be reduced. If 30% of the limit bending moment and lateral limit
force occur at the same time, only 40% of the longitudinal limit force is permissible and the nominal (rated)
torque must not be exceeded. The effects of permissible bending moments, longitudinal and lateral forces on
the measurement result are v"0.3% of the nominal (rated) torque.
The nominal (rated) torque must not be exceeded.
