3 Application

The T12 digital torque transducer records static and dynamic torque at
stationary or rotating shafts measures rotational speed or angle of rotation,
including indication of the direction of rotation, and computes the power. It is
designed for:

• highly dynamic torque measurements when testing the performance and
functionality of engines and compound sets

• high‐resolution speed and angle of rotation measurements

• fast, dynamic performance 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 torque, maximum speeds of up to
18 000 rpm

are permissible.

The T12 torque transducer is reliably protected against electromagnetic inter
ference. It has been tested with regard to EMC according to the relevant
European standards, and carries the CE mark.

Low pass LP2: 0.05 Hz ... 100 Hz

Low pass LP: 0.1 Hz ... 80 Hz

Fig. 4.1: Signal flow diagram

The torque and the temperature signal are already digitized in the rotor and
transmission is therefore noise‐free.

The torque signal can be zeroed

, scaled (2‐point scaling) and

filtered via two low passes (LP1 and LP2). A further scaling of the frequency
output and the analog output is then possible.

NOTE

Scaling at position

 (see Fig. 4.1) changes the internal calibration of

the torque transducer.

The speed signal can be filtered and also scaled for the analog output.
The angle of rotation signal, the performance signal (low pass filter LP) and

the temperature signal are only available on the fieldbusses.
The torque signal and the speed signal can be filtered via two low passes

connected in series, with the 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.

A1979-7.1 en HBM

12

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.

For rotational speed and angle of rotation, two pulse series with a shift of 90°
are available as RS‐422 compatible signals.

A1979-7.1 enHBM

T12

5 Structure and mode of operation

The torque transducer comprises two separate parts: the rotor and the stator.
Strain gages (SGs) for torque measurement have been installed on the rotor.

Carrier frequency technology (19.2 kHz carrier frequency) is used for
analyzing the SG and temperature signal. The rotor temperature is measured
at two measuring points and averaged.

The electronics for transmitting the bridge excitation voltage and the
measurement signal is located centrally in the rotor. The coils for the
noncontact transmission of excitation voltage and measurement signal are
located on the rotor's outer circumference of 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.

Connectors for inputs and outputs (for the connector pin assignment, see
chapter 8.3) 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 6).

In the case of the speed measuring system option, the speed sensor is
mounted on the stator, the customer attaches the associated slotted disc on
the rotor. The optical speed measurement works on the infrared transmitted
light principle.

6 Mechanical installation

WARNING

Handle the torque transducer carefully. The transducer might suffer
permanent damage from mechanical shock (e.g. dropping), chemical
effects (e.g. acids, solvents) or thermal effects (e.g. hot air, steam).

With alternating loads, you should glue the rotor connection screws into
the counter thread with a screw locking device (medium strength) to
exclude prestressing loss due to screw slackening.

The T12 torque transducer can be mounted directly with a relevant shaft
flange. It is also possible to directly mount a joint shaft or relevant compensat
ing element on opposite flange (using an intermediate flange when required).
Under no circumstances must the permissible limits specified for bending
moments, transverse and longitudinal forces be exceeded. Due to the torque
transducer's high torsional stiffness, dynamic changes on the shaft run are
minimized.

CAUTION

Check the effect on speeds and natural torsional oscillations critical to
bending, to prevent the transducer being overloaded by increases in
resonance.

6.1 Conditions on site

The T12 torque transducer is protected to IP54 according to EN 60529.
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 51). 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 temper
ature differences between flange A and flange B, the values given in the spe
cifications can be exceeded. Then for accurate measurements, you must

A1979-7.1 enHBM

T12

15

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.

6.2 Mounting position

The transducer can be mounted in any position. With clockwise torque, the
output frequency is 10...15 kHz (Option 4, Code DF1/DU2: 60 kHz ... 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...10 kHz (Option
4, Code DF1/DU2: 30 kHz ... 60 kHz).

In the case of the 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 speed signal is output.

6.3 Installing the slotted disc (speed measuring system
only)

To prevent damage to the speed measuring system's slotted disc during
transportation, it is not mounted on the rotor. Before installing the rotor in the
shaft run, the customer must attach it to the mounting ring. The mounting ring
and the associated speed sensor are already fitted at the factory.

The requisite screws, a suitable screwdriver and the screw locking device are
included in the list of components supplied.

CAUTION

When carrying out installation work, 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 screw locking device to the screw thread and tighten
the screws (tightening torque < 0.15 N⋅m).

6.4 Installing the rotor

T12

NOTE

In general, the rotor identification plate is no longer visible after
installation. This is why we include with the rotor additional stickers
with the important ratings, 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.
Data can also be accessed through T12 Assistent.
To explicitly assign the data, the identification number and the
measuring range are specified on the rotor where they can be seen from
outside.

A1979-7.1 enHBM

T12

17

Fig. 6.2: Screw connections, flange B

1. Prior to installation, clean the plane surfaces of the transducer flange and
the counter flange. For safe torque transfer, the surfaces 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 A screw connections, use hexagon‐socket screws DIN EN
ISO 4762 of property class 10.9 (measuring range 3 kN@m ... 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 or similar,
blackened, smoothheaded, permitted size and shape variance in
accordance with DIN ISO 4759, Part 1, product class A.

WARNING

With alternating load: Use a screw locking device (e.g. LOCTITE no. 242)
to glue the screws into the counter thread to exclude prestressing loss
due to screw slackening.

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.

A1979-7.1 en HBM

18

4. There are relevant tapped holes on flange A for continuing the shaft run
mounting. Again use screws of property class 10.9 (measuring range of
3 kN@m ... 10 kN@m: 12.9) and tighten them with the prescribed torque, as
specified in Table 6.1.

NOTE

Even if mounted correctly, the zero point adjusted at the factory may be
offset by up to 3 %. If this value has been exceeded, we recommend to
check the mounting conditions. If the remaining zero point offset is

greater than 1 % after dismounting, please send your transducer to our
factory in Darmstadt for evaluation.

CAUTION

With alternating loads, use a screw locking device to glue the
connecting screws into place. Guard against contamination from
varnish fragments.

6.6 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).

For installation with metric thread, we recommend using two
DIN EN ISO 4762

10.9 of the appropriate length (depending on the connection geometry; not
included among the components supplied; tightening torque = 14 N@m).

NOTE

fillister‐head screws with hexagon sockets of property class

Provide a possibility for adjustment (e.g. slotted holes) for aligning
stator and rotor.

The stator can be mounted radially in any position (for example, "upside
down" installation is possible). You can also install the stator over the
protection against contact (option), see chapter 6.6.3.

6.6.1 Preparing with the mounting kit (included among the items sup

plied)

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

Radial alignment with spacers

The spacers should preferably be attached to the transmitter head, offset by
90°, as shown in Fig. 6.14. If your stator is equipped with a speed measuring
system, you must either shorten the spacers to an appropriate length or bond
them on a slightly staggered manner next to the speed measuring system.

6.6.2 Aligning the stator

1. Position the stator on an appropriate base plate in the shaft run, 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. Initially, the fastening screws should only be hand‐tight.

4. Use the spacers to radially align the stator to the rotor.

A1979-7.1 enHBM

6. Connect the power line (connector 1 or connector 3). Notice the LED to
the right of connector 4. The stator is correctly aligned, when the LED
successively

• flashes red for about 10 seconds

• flashes yellow for about 10 seconds

• then stays permanently green (CAN bus) or yellow or green

(PROFIBUS).

NOTE

When data are being exchanged via the CAN bus or the PROFIBUS, the
LED flashes green.

You can also use the T12 Assistant to check for the correct alignment. The
LED must stay green in the "Rotor clearance setting mode".

7. Now fully tighten the fastening screws (tightening torque: 14 N@m).

8. Remove the spacers, by first removing the adhesive strip and then the red
plastic strip.

9. Make sure that the air gap between the rotor and stator is free from

electrically conductive and other foreign matter.

6.6.3 Stator installation over the protection against contact (option)

You can also axially flange the stator over the protection against contact
(material: aluminum). Holes are provided in the side parts of the protection
against contact for this purpose. For this mounting, we recommend
fillister‐head screws M6 with hexagon sockets in accordance with
DIN EN ISO 4762; black/oiled/m

=0.125, of the appropriate length.

6.7 Optical speed/angle of rotation measuring system
(option)

As the stator with the optical 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 speed measuring system
must rotate at a defined position in the sensor pickup.

Axial alignment

There is a mark (orientation line) in the sensor pickup for axial alignment
(orientation line). When installed, the slotted disc should be exactly above this
orientation line. Divergence of up to "2 mm is permissible in measuring
mode (total of static and dynamic shift).

8 Electrical connection

8.1 General hints

Detailed instructions for connecting the T12 to the CAN bus or the PROFIBUS
can be found in the "T12‐CAN bus/PROFIBUS" Internet 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 cable extensions, make sure that there is a proper connection with
minimum contact resistance and good insulation. All plug connections or
sleeve nuts must be properly 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.

CAUTION

Transducer connection cables from HBM with attached connectors 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!

NOTE

Cables and connectors for connections 1, 2 and 3 are compatible with
the T10FS torque flange.

8.2 Shielding design

The cable shielding is connected in accordance with the Greenline concept.
This encloses the measurement system (without a 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

A1979-7.1 en HBM

36

T12

measurement signal. Signal transmission between transmitter head and rotor
is purely digital and special electronic coding methods are used to protect
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

2

housing and the amplifier housing (copper conductor, 10 mm

wire cross

section).

If potential differences arise between the rotor and the stator on the machine,
perhaps due to unchecked leakage, and this causes interference, it can usu
ally be overcome by connecting the rotor directly to ground, for instance by a
wire loop. The stator should be fully grounded in the same way.

8.4.1 Supply voltage for self‐contained operation

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...30 V to pin 3 (+) and pin 2

) of connectors 1 or 3. We recommend that you use HBM cable

(
KAB 8/00-2/2/2 and the relevant female Binder connectors, that at nominal
(rated) voltage (24 V) can be up to 50 m long and in the nominal voltage
range, 20 m long (see Accessories, Page 77). If the permissible cable length
is exceeded, you can supply the voltage in parallel over two connection
cables (males connectors 1 and 3). This enables you to double the
permissible length. Alternatively an on‐site power pack should be installed.

, additional measures have to be taken for discharging over

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 on the cable, and the stator should
be grounded.

CAUTION

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.

9 Shunt signal

The T12 torque transducer supplies an electrical 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 activation on connector 1 or connector 3
(see chapter 8.3). The shunt signal selected last in the T12 Assistant will then
be activated.

NOTE

Due to the internal singal processing, activation of the shunt signal may
be delayed by about 5 seconds.

To obtain stable conditions, the shunt signal should only be activated once the
transducer has been warming up for 15 minutes.

To enable the values of the test report to be reproduced, the bonndary condi
tions of comparability (e. g. mounting conditions) have to be reproduced.

NOTE

When measuring the shunt signal, the transducer should not be loaded,
because the signal is applied in addition.
The shunt signal is automatically deactivated after about 5 minutes.

10 Loading capacity

Nominal (rated) torque can be exceeded statically up to the limit torque. If the
nominal 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" section, Page 51.

10.1 Measuring dynamic torque

11 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 device.

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 (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.
the conversion factors for the various engineering units.

A template is also stored, which provides

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!)

To read out the data and thus the parameterization of an MGC amplifier (such
as the ML60B or ML01B with AP01i), the relevant connection board is
connected to the T12 via cable KAB149 (torque) or KAB163 (speed).

You must then run the "TEDS" command in the MGC amplifier.
The MGC amplifier reads the data from the T12 TEDS block and parameters

are assigned accordingly.
You can also read the TEDS block data with the TEDS Editor.

CAUTION

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 MGC.

For more information on TEDS, look in the T12 Assistant online Help.

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:

12 Maintenance

The T12 torque transducer without speed measuring system is mainten
ance‐free.

12.1 Cleaning the speed measuring system

During operation and depending on the ambient conditions, the slotted disc of
the rotor and the associated stator sensor optics can get dirty. This becomes
noticeable:

• In transducers with a reference pulse, when an increment error is displayed
in the "Speed signal" status in the T12 Assistant

• In transducers without a reference pulse, when there are cyclic intrusions
into the 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 or

spirit‐impregnated cotton bud or cloth.

CAUTION

Do not use any other solvent for cleaning the sensor optic.

Each type of irregular stress can only be permitted with its given limit values (bending moment, lateral or
axial load, exceeding the nominal (rated) torque) if none of the others can occur. Otherwise the limit values
must be reduced. If for instance 30 % of the bending limit moment and also 30 % of the lateral limit force
are present, only 40 % of the axial limit force are permitted, provided that the nominal (rated) torque is not
exceeded. With the permitted bending moments, axial, and lateral limit forces, measuring errors of about

0.3 % of the nominal (rated) torque can occur.

The nominal (related) torque must not be exceeded.
