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 specifications.
Any other use is not appropriate.
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 “Additional safety precautions" section. Proper and safe operation
requires proper transportation, correct storage, siting and mounting, and care
ful operation.
Load carrying 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. For example, the values stated in the specifications must
not be exceeded for
Slimit torque,

Safety instructions
T40B A03452_15_X00_00 HBM: public 7
Slongitudinal limit force, lateral limit force or limit bending moment,
Storque oscillation width,
Sbreaking torque,
Stemperature limits,
Sthe limits of the electrical load‐carrying capacity.
Use as a machine element
The torque flange can be used as a machine element. When used in this man
ner, 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 “Load carrying capacity limits" and to the specifications.
Accident prevention
According to the prevailing accident prevention regulations, once the transduc
ers have been mounted, a covering agent or cladding has to be fitted as fol
lows:
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 arranged 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 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‐rele
vant) cutoffs. This requires additional components and constructive measures,
for which the installer and operator of the plant is responsible. The electronics

Safety instructions
8A03452_15_X00_00 HBM: public T40B
conditioning the measurement signal should be designed so that measurement
signal failure does not subsequently 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 engi
neering considerations in such a way as to minimize residual dangers. Perti
nent 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 reliable. Transduc
ers can give rise to residual dangers if they are incorrectly operated or inappro
priately 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 particular the tech
nical 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 (BG 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 property 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.

Application
12 A03452_15_X00_00 HBM: public T40B
3 Application
The T40B torque flange measures static and dynamic torques on stationary
and rotating shafts. Test beds can be extremely compact because of the com
pact design 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 according to harmonized European standards and/or
complies with US and Canadian standards. The product carries the CE mark
and/or FCC label.

Structure and mode of operation
T40B A03452_15_X00_00 HBM: public 13
4 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 gages (SGs) are installed on the measuring body. The rotor electronics
for transmitting the bridge excitation voltage and the measurement signal are
located centrally in the flange. The transmitter coils for contactless transmis
sion of excitation voltage and measurement signal are located on the measur
ing body's outer circumference. The signals are sent and received by a separa
ble antenna ring. The antenna ring is mounted on a housing that contains the
electronics for voltage adaptation and the signal conditioning.
Connector plugs for the torque and rotational speed signals, the voltage supply
and digital output, are located on the stator. The antenna segments (the
antenna ring) must be mounted concentrically around the rotor (see chapter 5).

In the version with a rotational speed measuring system, the transducer can
also be fitted with a sensor head for a reference signal (zero index) for measur
ing the angle of rotation. The magnet to be used for this is located on the inner
surface of the flange. The sensor head for sampling the reference signal is
located in the bracket above the rotational speed sensor.

5.1 Important precautions during installation
Notice
A torque flange is a precision measuring element and therefore needs careful
handling. Dropping or knocking the transducer may cause permanent damage.
Make sure that the transducer cannot be overloaded, including while it is being
mounted.
SHandle the transducer with care.
SCheck the effect of bending moments, critical rotational speeds and natural
torsional vibrations, to prevent the transducer being overloaded by reso
nance sharpness.
SMake sure that the transducer cannot be overloaded.
WARNING
There is a danger of the transducer breaking if it is overloaded. This can cause
danger for the operating personnel of the system in which the transducer is
installed.
Implement appropriate safety measures to avoid overloads and to protect
against resulting dangers.
SUse a threadlocker (medium strength, e.g. LOCTITE) to glue the screws
into the counter thread to exclude prestressing loss due to screw slacken
ing, in the event of alternating loads.
SComply with the mounting dimensions to enable correct operation.
An appropriate shaft flange enables the T40B torque flange to be mounted
directly. It is also possible to mount a joint shaft or relevant compensating ele
ment directly on the rotor (using an intermediate flange when required). Under

Mechanical installation
T40B A03452_15_X00_00 HBM: public 17
no circumstances should the permissible limits specified for bending moments,
lateral and longitudinal forces be exceeded. Due to the T40B torque flange's
high torsional stiffness, dynamic shaft train changes are kept to a minimum.
Important
Even if the unit is installed correctly, the zero point adjustment made at the fac
tory can shift by up to approx. 2% of the sensitivity. If this value is exceeded,
we advise you to check the mounting conditions. If the residual zero offset
when the unit is removed is greater than 1% of the sensitivity, please send the
transducer back to the Darmstadt factory for testing.
5.2 Conditions on site
The T40B torque flange must be protected against coarse dirt particles, dust,
oil, solvents and moisture.
There is wide ranging compensation for the effects of temperature on the out
put and zero signals of the transducer (see “Specifications" section). If there
are no static temperature ratios, for example, because of the temperature dif
ferences between the measuring body and the flange, the values given in the
specifications can be exceeded. In this case, ensure static temperature ratios
by cooling or heating, depending on the application. As an alternative, check if
thermal decoupling is possible, e.g. by means of heat radiating elements such
as multiple disc couplings.
5.3 Installation orientation
The torque flange can be installed with any orientation.
With clockwise torque, the output frequency is 60 to 90 kHz for Option 5, Code
DU2 (Option 5, Code SU2: 10 to 15 kHz; Option HU2: 240 to 360kHz). In con
junction with HBM amplifiers or when using the voltage output, a positive out
put signal (0 V to +10 V) is present. In the case of the rotational speed measur
ing system, an arrow is attached to the stator housing to clearly define the
direction of rotation: if the measurement flange turns in the direction of the
arrow, connected HBM measuring amplifiers deliver a positive output signal.

5.4 Installation options
There are basically two options for mounting the torque flange: with or without
dismantling the antenna ring. We recommend mounting as described in Chap
ter 5.4.1. If mounting in accordance with Chapter 5.4.1 is not possible, (e.g. in
the case of subsequent stator replacement), you will have to dismantle the
antenna ring. It is essential in this case to comply with the notes on assembling
the antenna segments (see Chapter 5.4.2).
