Safety instructions
Designated use
The T10FM torque flange is used exclusively for torque and rotation speed
measurement tasks, and directly associated control and regulatory tasks. Use
for any additional purpose shall be deemed to be not as intended.
In the interests of safety, the transducer should only be operated as described
in the Operating Manual. It is also essential to comply with the legal and
safety requirements for the application concerned during use. The same
applies to the use of accessories.
The transducer is not a safety element within the meaning of its designated
use. Proper and safe operation of this transducer requires proper
transportation, 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 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, equipment 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. On‐site regulations must be complied with
at all times. Reference must be made to remaining dangers connected with
torque measurement technology.

The following symbols are used in this Operating Manual to point out
remaining dangers:
Symbol: DANGER
Meaning: Maximum danger level
Warns of an imminently dangerous situation in which failure to comply with
safety requirements will result in death or serious physical injury.
Symbol: WARNING
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: ATTENTION
Meaning: Possibly 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.
Symbols for application and disposal instructions, as well as useful
information:
Means that important information about the product or its handling is being
provided.
Symbol:
Meaning: CE mark
The CE mark enables the manufacturer to guarantee that the product
complies with the requirements of the relevant EC directives (the Declaration
of Conformity can be found at http://www.hbm.com/hbmdoc).

Symbol:
Meaning: Statutory waste disposal mark
In accordance with national and local environmental protection and material
recovery and recycling regulations, old devices that can no longer be used
must be disposed of separately and not with normal household garbage.
If you need more information about waste disposal, please contact your local
authorities or the dealer from whom you purchased the product.
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.
Qualified personnel
The transducer must only be installed and used by qualified personnel, strictly
in accordance with the specifications and with safety requirements and
regulations. It is also essential to comply with the legal and safety
requirements for the application concerned during use. The same applies to
the use of accessories.
Qualified personnel means persons entrusted with siting, mounting, starting
up and operating the product who possess the appropriate qualifications for
their function.

Accident prevention
According to the prevailing accident prevention regulations, once the torque
flange has been mounted, a covering agent or cladding has to be fitted as
follows:
The cover or cladding must not be free to rotate.
The cover or cladding should avoid squeezing or shearing and provide
protection against parts that might come loose.
Covers and cladding must be positioned at a suitable distance or be
arranged so that there is no access to any moving parts within.
Covers and cladding must also be attached if the moving parts of the
torque flange are installed outside peoples' movement and operating
range.
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.
Warranty
In the case of complaints, a warranty can only be given if the torque flange is
returned in the original packaging.

2 Application
The T10FM torque flanges record static and dynamic torque on stationary or
rotating shafts and determine the speed, specifying the direction of rotation.
Test beds can be extremely compact because of their extremely short
construction. They therefore offer a very wide range of applications.
In addition to conventional test‐bench engineering (engine, roll and
transmission test benches), new solutions are possible for torque
measurements partly integrated in the machines.
Thanks to the bearing‐free design and the contactless transmission of
excitation voltage and measured values, the torque measuring system of
torque flanges requires no maintenance. Thus there are no friction or bearings
heating effects.
The torque flanges are supplied for nominal (rated) torques from 15 kNm to
80 kNm. Depending on the nominal torque, maximum speeds of up to 6000
min-1 are permissible.
T10FM torque flanges are reliably protected against electromagnetic
interference. They have been tested with regard to EMC according to the
relevant European standards, and carry the CE mark.

3 Structure and mode of operation
The torque flange consist of two separate parts: the rotor and the stator. The
stator comprises an antenna ring and a housing.
Strain gauges (SGs) are mounted on the rotor. The rotor electronics for
transmitting the bridge excitation voltage and the measurement signal are
located centrally in the flange. The coils for the non‐contact transmission of
excitation voltage and measurement signal are located on the rotor's outer
circumference. The signals are sent and received by a separable antenna
ring. The antenna ring is mounted on a housing that includes the electronic
system for voltage adaptation and signal conditioning.
Connectors for the torque signal, the voltage supply and the speed signal
(option) are located on the stator. The antenna ring should be mounted
concentrically around the rotor (see Chapter 4).
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.
