Safety Instructions
Appropriate use
The T40B torque flange is used exclusively for torque, angle of rotation and
power measurement tasks within the load limits stipulated in the specifica
tions. Any other use is not the designated use.
Stator operation is only permitted when the rotor is installed.
The torque flange may only be installed by qualified personnel in compliance
with the specifications and with the safety requirements and regulations of
these mounting instructions. It is also essential to observe the applicable legal
and safety regulations for the application concerned. The same applies to the
use of accessories.
The torque flange is not intended for use as a safety component. Please also
refer to the section: “Additional safety precautions". Proper and safe operation
requires proper transportation, correct storage, siting and mounting, and care
ful operation.
Loading capacity limits
The data in the technical data sheets must be complied with when using the
torque flange. In particular, the respective maximum loads specified must
never be exceeded. The values stated in the specificationsmust not be
exceeded, for example, for
limit torque,
longitudinal limit force, lateral limit force or limit bending moment,
torque oscillation width,
breaking torque,
temperature limits,
the limits of the electrical loading capacity.
Use as a machine element
The torque flange can be used as a machine element. When used in this
manner, it must be noted that, to favor greater sensitivity, the transducer is not
designed with the safety factors usual in mechanical engineering. Please refer
here to the section “Loading capacity limits", and to the specifications.
Accident prevention
According to the prevailing accident prevention regulations, once the trans
ducers have been mounted, a covering agent or cladding has to be fitted as
follows:
The covering agent or cladding must not be free to rotate.
T40B
6
A3452-4.0 en/deHBM
The covering agent or cladding should prevent squeezing or shearing and
provide protection against parts that might come loose.
Covering agents and cladding must be positioned at a suitable distance or
be so arranged that there is no access to any moving parts within.
Covering agents and cladding must still be attached even if the moving
parts of the torque flange are installed outside people's movement and
working range.
The only permitted exceptions to the above requirements are if the torque
flange is already fully protected by the design of the machine or by existing
safety precautions.
Additional safety precautions
The torque flange cannot (as a passive transducer) implement any (safety‐rel
evant) cutoffs. This requires additional components and constructive meas
ures for which the installer and operator of the plant is responsible. The layout
of the electronics conditioning the measurement signal should be such that
measurement signal failure does not cause damage.
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 safety engin
eering considerations in such a way as to minimize residual dangers. Pertin
ent national and local regulations must be complied with.
General dangers of failing to follow the safety instructions
The torque flange corresponds to the state of the art and is failsafe. Trans
ducers can give rise to residual dangers if they are incorrectly operated or
inappropriately mounted, installed and operated by untrained personnel.
Every person involved with siting, starting‐up, operating or repairing a torque
flange must have read and understood the mounting instructions and in partic
ular the technical safety instructions. The transducers can be damaged or
destroyed by non‐designated use of the transducer or by non‐compliance with
the mounting and operating instructions, these safety instructions or any other
applicable safety regulations (safety and accident prevention regulations),
when using the transducers. Transducers can break, particularly in the case of
overloading. The breakage of a transducer can also cause damage to prop
erty or injury to persons in the vicinity of the transducer.
If the torque flange is not used according to the designated use, or if the
safety instructions or specifications in the mounting and operating instructions
are ignored, it is also possible that the transducer may fail or malfunction, with
the result that persons or property may be adversely affected (due to the
torques acting on or being monitored by the torque flange).

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.
Selling on
If the torque flange is sold on, these mounting instructions must be included
with the torque flange.
Qualified personnel
Qualified personnel means persons entrusted with siting, mounting, starting
up and operating the product, who possess the appropriate qualifications for
their function.
This includes people who meet at least one of the three following require
ments:
- Knowledge of the safety concepts of automation technology is a require
ment and as project personnel, you must be familiar with these concepts.
- As automation plant operating personnel, you have been instructed how to
handle the machinery. You are familiar with the operation of the equipment
and technologies described in this documentation.
- As commissioning engineers or service engineers, you have successfully
completed the training to qualify you to repair the automation systems. You
are also authorized to activate, ground and label circuits and equipment in
accordance with safety engineering standards.

2 Application
The T40B torque flange measures static and dynamic torques on stationary
and rotating shafts. Test beds can be extremely compact because of the short
construction of the transducer. This offers a very wide range of applications.
The T40B torque flange is reliably protected against electromagnetic interfer
ence. It has been tested with regard to EMC according to the relevant
European standards, and carries the CE mark.

A3452-4.0 en/deHBM
3 Structure and mode of operation
The torque flange consists of two separate parts: the rotor and the stator. The
rotor comprises the measuring body and the signal transmission elements.
Strain gauges (SGs) are installed on the measuring body. The rotor electron
ics for transmitting the bridge excitation voltage and the measurement signal
are located centrally in the flange. The transmitter coils for contactless trans
mission of excitation voltage and measurement signal are located on the
measuring body's outer circumference. The signals are sent and received by
a separable antenna ring. The antenna ring is mounted on a housing that con
tains the electronics for voltage adaptation and the signal conditioning.
Connector plugs for the torque and speed signals, the voltage supply and
digital output, are located on the stator. The antenna segments (ring) should
be mounted more or less concentrically around the rotor (see chapter 4).

Fig 3.1: Mechanical construction without a rotational speed measuring system
The speed sensor is mounted on the stator in Option 6 with a rotational speed
measuring system. The rotational speed is measured magnetically with an
AMR sensor and a magnetic ring. The magnetic ring for measurement of rota
tional speed is welded to the flange.
