If the transducer is used and operated inappropriately by untrained personnel,
residual dangers may arise.
Anyone responsible for installing, operating, maintaining or repairing this
transducer must be sure to have read and understood the operating manual
and in particular the notes on safety.
Residual dangers
The scope of performance and supply of this transducer covers only part of
the torque measurement technology. In addition, those involved in planning,
constructing and operating the safety engineering aspects of torque
measurement technology must design, produce and take responsibility for
such measures in order to minimise potential residual dangers. Prevailing
regulations must be complied with at all times. There must be a clear
reference to the residual dangers connected with measurement technology.

Meaning: Dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements can result in death or serious physical injury.
Symbol: CAUTION
Meaning: Potentially dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements could result in damage to property or some form of
physical injury.
Symbol: NOTE
Means that important information about the product or its handling is being
given.
Symbol:
Meaning: CE mark
The CE mark enables the manufacturer to guarantee that the product
complies with the requirements of the relevant EC guidelines (see Declaration
of Conformity at the end of these Mounting Instructions).

Reconstruction and modifications
HBM’s express consent is required for modifications affecting the transducer’s
construction and safety. HBM does not take responsibility for damage
resulting from unauthorised modifications.
Qualified personnel
The transducer may be used by qualified personnel only; the technical data
and the special safety regulations must be observed in all cases. When using
the transducer, the legal and safety regulations for the respective application
must also be observed. The same applies if accessories are used.
Qualified personnel means: personnel familiar with the installation, fitting,
start–up and operation of the product, and trained according to their job.
Prevention of accidents
According to prevailing accident prevention regulations, after fitting the T10F
torque transducers a cover must be fitted as follows:
•The cover must not be able rotate.
•The cover shall protect against crushing or cutting and provide protection
against parts that might come loose.
•The cover shall be installed at a safe distance from moving parts or shall
prevent anyone putting their hand inside.
•The cover shall even be fitted if the moving parts are installed in areas to
which persons do not usually have access.
The above regulations may only be disregarded if machine parts are already
sufficiently protected owing to the design of the machine or because other
precautions have been taken.
Guarantee
In the event of a claim, the guarantee can only be considered if the torque
flange is returned in its original packing.

1 Versions of the torque flange
In the case of option 2 “Electrical Configuration”, the T10F torque flange is
available in versions KF1, SF1 and SU2. These versions differ in their
electrical inputs and outputs to the stator. The rotors are the same for all
measuring range versions. Versions SF1 and SU2 can be optionally fitted with
a speed measuring system.

2 Application
T10F Torque Flanges acquire static and dynamic torque data from static or
rotating shafts and determine rotation speed together with information on the
direction of rotation. Due to their extremely short design they enable very
compact test arrangements to be used. They offer a very wide range of
applications.
In addition to conventional test-rig applications (motor, roller and gear
test-rigs) new solutions are possible for torque measurements partly
integrated into the machines. Here you benefit from the special characteristics
of the T10F Torque Flange:
•Extremely short design due to flange measuring–body
•High permissible dynamic loads
•High permissible transverse forces and bending moments
•Very high torsional stiffness
•No bearings, no slip-rings
Due to their construction without bearings and the contact–free transmission
of excitation voltage and measurement, torque flanges are maintenance–free.
Thus, frictional or thermal effects on the bearings can be excluded.
The torque flanges are supplied for nominal (rated) torques from 50 N⋅m up to
10 kN⋅m. Depending on the nominal torque, maximum speeds of up to
15,000 rpm are permissible.
T10F Torque Flanges are protected from electromagnetic interference. They
have been tested with regard to EMC according to the relevant European
standards, and carry the CE mark.

3 Design and function
Torque flanges consist of two separate parts: the rotor and the stator. The
rotor includes the measuring body and the adapter flange.
Strain gauges have been mounted on the measuring body. The rotor
electronics for transmitting the bridge excitation voltage and measuring signal
are located centrally on the flange. The top surface of the measuring body
supports the transmitter coils for contact–free transmission of excitation
voltage and measuring signal. The signals are transmitted and received by a
divisible antenna ring. The antenna ring is mounted on a housing that includes
the electronic system for voltage adaption and signal conditioning.
The stator includes connecting plugs for the torque signal, the power supply
and the rotation speed signal (optional). The antenna ring should be mounted
concentrically around the rotor (see chapter 4).
In the case of the option which includes a rotation speed measurement
system, the rotation speed sensor is mounted on the stator and the customer
fastens the associated slotted disc to the rotor. Rotation speed is measured
optically in accordance with the principle of infrared transmitted light barriers.
