SAFETY INSTRUCTIONS
1 SAFETY INSTRUCTIONS
Intended use
The T210torque transducer is used exclusively for torque and rotation speed measure
ment tasks, and directly associated control and regulatory tasks. Use for any purpose
other than the above is deemed improper use.
In the interests of safety, the transducer should only be operated as described in the
Operating Manual. During use, compliance with the legal and safety requirements for the
relevant application is also essential. The same applies to the use of accessories.
The transducer is not a safety element within the meaning of appropriate use. Proper and
safe operation of this transducer requires proper transportation, correct storage, assem
bly 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 failsafe. The transducer can
give rise to remaining dangers if it is inappropriately installed and operated by untrained
personnel.
Everyone involved with mounting, starting up, maintaining, or repairing the transducer
must have read and understood the Operating Manual and in particular the technical
safety instructions.
Residual dangers
The scope of supply and performance of the transducer covers only a small area of
torque measurement technology. In addition, system planners, installers and operators
should plan, implement and respond to the safety engineering considerations of torque
measurement technology in such a way as to minimize remaining dangers. Existing regu
lations must be complied with at all times. Reference must be made to remaining dan
gers connected with torque measurement technology.
Conversions and modifications
The design or safety engineering of the transducer must not be modified without our ex
press permission. Any modification shall exclude all liability on our part for any resulting
damage.
Qualified personnel
The transducer must only be installed and used by qualified personnel, strictly in accor
dance with the specifications and with safety requirements and regulations. During use,
compliance with the legal and safety requirements for the relevant application is also
essential. The same applies to the use of accessories.

Qualified personnel means persons entrusted with siting, mounting, starting up and oper
ating the product who possess the appropriate qualifications for their function.
Accident prevention
According to the prevailing accident prevention regulations, once the torque transducers
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 ar
ranged 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 transducer are installed outside peoples' movement and working range.
The only permitted exceptions to the above requirements are if the various parts and as
semblies of the machine are already fully protected by the design of the machine or by
existing safety precautions.

MOUNTING
4.3 Couplings
HBK offers bellows couplings for installation of the torque transducer. The following
points must be observed when installing:
1. Degrease the hub hole in each coupling half and the shaft ends with solvent (e.g. ace
tone).
2. Push the hub onto the shaft.
3. Adjust the air gap to the transducer, which should be min. 1mm from the transducer
housing, or push the coupling onto the shaft until it reaches the limit stop.
4. Using the full clamping length, align the coupling and shafts.
5. Tighten the clamping bolts of the clamp with a torque wrench (see Specifications for
the required torque).
Notice
Do not tighten the clamping bolts of the couplings until the shafts have been installed in
the coupling hubs!
The bellows coupling must not be stretched beyond the permissible compliance.
Input and output shafts must be free of grease and burrs.
Make the shaft diameters with j6 tolerance to obtain the preferred H7/j6 fit.
When selecting the coupling, the specifications of the transducer – and in particular the
maximum permissible mechanical stresses – must be taken into account in addition to the
specifications of the coupling.
4.3.1 Mounting position with couplings
The T210torque transducer can be operated with bellows couplings in any mounting po
sition (horizontally, vertically or at an angle). Please ensure that additional masses are
adequately supported during vertical and inclined operation.
The specifications and the mounting instructions for the couplings can be found in the
data sheet of the bellows couplings.
CAUTION
The permissible axial and lateral forces and the bending moment limits of the torque trans
ducer must not be exceeded when mounting couplings!
Brace the coupling by the clamp when tightening the clamping bolts.

ELECTRICAL CONNECTION
10
5 ELECTRICAL CONNECTION
5.1 General information
For the electrical connection between the torque transducer and measuring amplifier we
recommend using shielded, low-capacitance measuring cables.
With extension cables, make sure that there is a proper connection with minimum contact
resistance and good insulation. All plug connections or swivel nuts must be tightened
firmly.
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 measuring cable into a steel tube.
Avoid transformers, motors, contactors, thyristor controls and similar stray-field sources.
5.2 Connector plug
The transducer is equipped with a permanently mounted housing connector.
It can be connected to the corresponding measurement electronics via the transducer
connection cable (available as an accessory). Please refer to the following table for the
pin assignment of the transducer connection cables.

Fig. 5.1 Connection diagram T210
The transducer generates an internally electrically isolated measurement signal. The
grounds must not be bridged directly on the transducer, otherwise measurement errors
may occur depending on the supply and analysis device. If necessary they can be bridged
on the supply and analysis device. The "control signal" is used to test the transducer. It is
connected to the torque outputs at 50% of the nominal signal. The modulation level is
4.5 V up to the supply voltage. The reference voltage is the supply ground.
The transducer has a ready for measurement signal. If the output is returning a HIGH
level, normally the measurement electronics are working. With a LOW level there is an
error.
5.3 Extending the cable
Extension cables must be shielded and of low capacitance.
With cable extensions it is important to ensure that a good connection is provided, with
minimum contact resistance and good insulation. So all connections should be soldered,
or at least made with secure, stable clamp terminals or screwed plug connectors.

13
T210
ELECTRICAL CONNECTION
Measuring cables should not be laid parallel to power cables and control circuits (that is,
not in shared cable ducts). If this is not possible, protect the measurement cable with a
rigid steel conduit, for example, and keep it as far away from other cables as possible.
Avoid stray fields from transformers, motors and contact switches.
Notice
At the maximum rotational speed of 30,000 rpm the cable length is limited to maximum
10 m.
5.4 Shielding design
The cable shield 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.
In the event of interference due to potential differences (compensating currents), discon
nect supply voltage zero from the housing ground at the measuring amplifier and lay a
potential equalization line between the transducer housing and the measuring amplifier
housing (copper cable, 10 mm2cable cross-section).

6 LOAD-CARRYING CAPACITY
The T210can be used to measure static and dynamic torques.
Nominal (rated) torque can be exceeded statically up to the torque limit. If the nominal
torque is exceeded, additional irregular loading is not permissible. This includes axial
force and lateral forces and bending moments. The limit values can be found in chapter
10 "Specifications", page 22.
6.1 Measuring dynamic torque
When measuring dynamic torques, please note:
SThe calibration performed for static torques is also valid for dynamic torque measure
ments.
Notice
The frequency of the dynamically acting torques must be lower than the natural fre
quency of the mechanical measuring arrangement.
SThe natural frequency f0of the mechanical measuring arrangement depends on the
moments of inertia J1and J2of the two connected rotating masses and the torsional
stiffness of the transducer.
The equation below can be used to determine the natural frequency f0of the mechanical
measuring arrangement.

6.2 Rotational speed
A slotted disk is installed on the loaded member. This is scanned by an encoder in the
housing. The T210returns two 90° offset square wave signals with 512 pulses per revolu
tion at the output. Detection of the direction of rotation is possible with this angle. In
clockwise rotation, channel B (pin G) lags channel A (pin B) by 90°.

The rotational speed reference signal Z is additionally outputted on pin H. It is also a 5 V
square wave signal. At 1 pulse per revolution, it is suitable for measuring high rotational
speeds, as this places lower demands on the evaluation unit.
Information
The T210torque transducers are suitable for a nominal (rated) rotational speed of max.
30,000 rpm depending on the nominal (rated) measuring range.
Tip
To ensure an optimum distribution of grease in the bearing, turning the measurement shaft
once before the start of the measurement with the maximum expected rotational speed is
recommended.

MAINTENANCE
18
8 MAINTENANCE
The T210torque transducer is largely maintenance-free. We recommend having the low-
friction special bearings replaced at the factory after approximately 20,000 operating
hours. It is also a good idea to have a calibration performed at this point at the latest.
