tended. Proper and safe operation of this transducer requires proper trans-
portation, correct storage, assembly and mounting and careful operation.
General dangers of failing to follow the safety instructions
The transducer corresponds to the state of the art and is fail-safe. The
transducer can give rise to remaining dangers if it is inappropriately installed
and operated by untrained personnel.
Everyone involved with the installation, commissioning, maintenance or repair
of the transducer must have read and understood the Operating Manual and in
particular the technical safety instructions.
Remaining dangers
The scope of supply and performance of the transducer covers only a small
area of torque measurement technique. In addition, equipment planners,
installers and operators should plan, implement and respond to the safety
engineering considerations of torque measurement technique in such a way as
to minimize remaining dangers. Prevailing regulations must be complied with
at all times. Reference must be made to remaining dangers connected with
torque measurement technology.

Prevention of accidents
In accordance with the health and safety regulations relevant to accident
prevention, once the operator has fitted the torque transducer, a cover or
cladding must be attached as follows:
•The cover or cladding must not be free to rotate.
•The cover or cladding must prevent access to any areas where crushing or
shearing could occur, and must provide protection against any parts that
may come loose.
•Covers and cladding must be positioned at a suitable distance or so
arranged that it prevents access to any moving parts within.
•Covers and cladding must also be attached if the moving parts of the torque
transducers are installed outside the area in which people are moving about
and working.
The only permitted exceptions to the above requirements are if the various
parts and assemblies of the machine are already fully protected by the design
of the machine or by existing safety precautions.

2.3 Couplings
HBM supplies bellows couplings for installation of the torque transducer. The
couplings and the torque transducer are delivered as separate units. The
following points must be observed during installation:
•Only tighten the clamping screws of the couplings once the shafts are
installed in the coupling hubs!
•The bellows-type coupling must not be overstretched beyond the specified
permissible flexibility.
•Drive and output shafts must be without burr.
•Run the shaft diameter with j6 tolerance, to produce the H7/j6 preferred fit.
2.3.1 Installation position with couplings
With the bellows couplings, the T22 torque transducer can be operated in any
installation position (horizontal, vertical or diagonal). With vertical and diagonal
operation, make sure that additional masses are adequately supported.
2.3.2 Installation
1. Degrease the hub bore of each coupling half member and the shaft ends
with solvent (for example, acetone).
2. Push the hub onto the shaft, set the reference gap L (making use of the full
clamping length of the coupling) and align the shafts.
3. Tighten the clamping screws of the clamping element with a torque wrench
(for the required tightening torque, see Chapter 9.2.2).
CAUTION
When installing the coupling, you must not exceed the permissible
longitudinal and lateral forces or bending limit moments (see Chapter
8) of the torque transducer!
When tightening the clamping screws, hold the coupling on the
clamping element.

3 Electrical connection
3.1 General instructions
We recommend to use shielded, low−capacitance cable from HBM for the elec-
trical connection between torque transducer and measuring amplifier.
With cable extensions it is important to ensure that a good connection is pro-
vided, with minimum contact resistance and good insulation. All plug connec-
tions or cap nuts have to be tightened firmly.
Do not route measurement cables in parallel to power lines and control circuits.
If this is not possible (for example in cable ducts), maintain a minimum dis-
tance of 50 cm and protect the cable with a steel tube.
Avoid transformers, motors, contactors, thyristor controllers and similar
sources of stray fields.
3.2 Connector
The transducer is equipped with a permanent housing connector.
It can be connected to the relevant measurement electronics by using the
transducer connection cable (accessories, see Page 19). The pin assignment
for the transducer connection cable can be found in the following table:

T22
HBMA2302-2.0 en/de
3.3 Cable extension
Extension cables must be the shielded, low-capacitance type. We recommend
the use of HBM cables that comply with these requirements.
When using cable extensions, ensure that the connection is perfect, with the
lowest possible contact resistance and good insulation. For this reason all
connections should be soldered, or at the very least should use firmly fixed
terminals or screwed connectors.
Measurement cables should not be laid parallel to high-voltage lines or control
circuits (and therefore should not be laid in common cable shafts). If this is not
possible, protect the measurement cable with, for example, armoured steel
tubing and keep them as far away as possible from other cables. Avoid the
stray fields of transformers, motors and contactors.
3.4 Shielding design
The cable shielding is connected in accordance with the Greenline concept.
This encloses the measurement system 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. Please comply with the connection notes.
In the case of interference caused by differences in potential (compensating
currents), separate the connections between the zero operating voltage and
the housing ground on the measuring amplifier and connect a potential
equalization line between the transducer housing and the amplifier housing
(copper wire, 10 mm2conductor cross-section).

4 Load-carrying capacity
The T22 torque transducer is suitable for measuring static and dynamic torque.
Nominal torque can be exceeded statically up to the limit torque. If 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” chapter, Page 15.
4.1 Measuring dynamic torque
The following applies to the measurement of dynamic torque:
•The calibration carried out for static torque also applies for dynamic torque
measurement.
NOTE
The frequency of the dynamic torque must be lower than the natural
frequency of the mechanical measuring system.
•The natural frequency f0of the mechanical measuring system depends on
the moments of inertia J1and J2of the coupled rotating masses and on the
torsional stiffness of the transducer.
The natural frequency f0of the mechanical measuring system can be
determined from the following equation.

J2Ǔ
Ǹf0= Natural frequency in Hz
J1, J2= Moment of inertia in kg⋅m2
cT= Torsional stiffness in N⋅m/rad
•The vibration bandwidth (peak-to-peak) must not exceed 80 % of the
nominal torque identified for the torque transducer, even at alternating load.
In all cases the vibration bandwidth must lie within the loading range defined
by −Mnom and +Mnom.

The T22 torque transducer allows torque measurements of 9000 rpm up to
16000 rpm, depending on the measuring range. Limit values see Chapter 8.
5 Displaying torque
Torque
If a clockwise torque is applied, there is a positive output signal (0...+5 V,
respectively +10...+18 mA).
6 Maintenance
The T22 torque transducer is largely maintenance free. We recommend that
the low-friction special bearing should be replaced at the Darmstadt factory,
after approx. 20 000 working hours. The calibration will also be checked at this
time.
