Intended use
The T40MS 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 the designated use.
Stator operation is only permitted when the rotor is installed.
The T40MS 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 T40MS 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 careful operation.
Loading capacity limits
The data in the technical data sheets must be complied with when using the T40MS torque
flange. In particular, the respective maximum loads specified must never be exceeded. The
following limits set out in the specifications must not be exceeded, e.g.:
•Limit torque
•Longitudinal limit force, lateral limit force or bending limit moment
•Torque vibration bandwidth
•Breaking torque
•Temperature limits
•Limits of electrical loading capacity
Use as a machine element
The T40MS 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 transducers 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.
•The covering agent or cladding should prevent squeezing or shearing and
provide protection against parts that might come loose.
•Covers 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
T40MS torque flange are installed outside peoples' movement and working range.
The only permitted exceptions to the above requirements are if the T40MS torque flange
is already fully protected by the design of the machine or by existing safety precautions.
Additional safety precautions
The T40MS torque flange cannot (as a passive transducer) implement any (safety-
relevant) cutoffs. This requires additional components and constructive measures 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 engineering considerations in such a way as to
minimize residual dangers. Pertinent national and local regulations must be complied with.
General dangers of failing to follow the safety instructions
The T40MS torque flange is state of the art and reliable. Transducers 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 T40MS torque flange must have read and understood the mounting instructions
and in particular 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 (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 T40MS 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 affected (due to the torques acting on or being monitored by the T40MS
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.

2 Application
The T40MS 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 T40MS torque flange is reliably protected against electromagnetic interference. It has
been constructed according to the relevant European standards (e.g. EMC behavior) and/or
complies with US and Canadian standards. The product carries the CE mark and/or FCC
label.

HBM T40MS 2020 en (11.03.2020) HBM: public
3 Structure and mode of operation
The T40MS 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 electronics for
transmitting the bridge excitation voltage and the measurement signal are located centrally
in the flange. The transmitter coils for contactless transmission 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 includes the electronic system for voltage adaptation and signal conditioning.
Connectors for the torque and speed signals, the voltage supply and the digital output
are located on the stator. The antenna segments (ring) should be mounted more or less
concentrically around the rotor (see Chapter 4).

The rotational speed sensor is mounted on the stator in Option 6 with a rotational speed
measuring system. The rotational speed is measured magnetically via an AMR sensor and a
magnetic ring. The magnetic ring for measuring the rotational speed is welded to the flange.
Fig. 3.2: Mechanical construction with a rotational speed measuring system
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 measuring 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.

4 Mechanical installation
4.1 Important precautions during installation
NOTE
A T40MS torque flange is a precision measurement element and therefore needs careful
handling. Dropping or knocking the transducer may cause permanent damage. Make
sure that the transducer cannot be overloaded, even while it is being mounted.
•Handle the transducer with care.
•Check the effect of bending moments, critical speeds and natural torsional
oscillations, to prevent the transducer being overloaded by increases in
resonance.
•Make 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.
•Use a screw locking device (medium strength, e.g. LOCTITE No. 242) to glue the
screws into the counter thread to exclude prestressing loss due to screw
slackening, if alternating loads are to be expected.
•Comply with the mounting dimensions to enable correct operation.
An appropriate shaft flange enables the T40MS torque flange to be mounted directly. It is
also possible to mount a joint shaft or relevant compensating element directly on the rotor
(using an intermediate flange when required). Under no circumstances should the
permissible limits specified for bending moments, lateral and longitudinal forces be
exceeded. Due to the T40MS torque flange's high torsional stiffness, dynamic shaft train
changes are kept to a minimum.

12
HBM T40MS 2020 en (11.03.2020) HBM: public
Important
Even if the unit is installed correctly, the zero point adjustment made at the factory 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.
4.2 Conditions on site
The torque flange must be protected against coarse dirt particles, dust, oil, solvents and
humidity.
There is wide ranging compensation for the effects of temperature on the output and zero
signals of the transducer (see Chapter "Specifications"). If there are no static temperature
ratios, for example, because of the temperature differences 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.
4.3 Mounting position
The T40MS torque flange can be mounted in any position.
With clockwise torque, the output frequency is, depending on the option, 60 - 90 kHz, 10 -
15 kHz or 240 - 360 kHz). With HBM amplifiers or with the voltage output option, a positive
output signal (0 V -+10 V) is present.
4.4 Installation options
For T40MS torque flange mounting 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 4.4.1).

4.5 Mounting the rotor
T ip
Usually the rotor identification plate is no longer visible after installation. This is why we
include with the rotor additional stickers with the important ratings, which you can attach to
the stator or any other relevant test-bench components. You can then refer to them
whenever there is anything you wish to know, such as the shunt signal.
1. Prior to installation, clean the plane surfaces of the transducer flange and the counter
flange.
For safe torque transfer, the surfaces must be clean and free from grease. Use a piece
of cloth or paper soaked in solvent. When cleaning, make sure that you do not damage
the transmitter winding or the speed measuring system.
2. For the bolted rotor connection (see Fig. 4.9), use DIN EN ISO 4762 hexagon socket
screws of the property class stated in Table 4.1, in a suitable length (dependent on the
connection geometry, see Table 4.1 on Page 14).
We recommend DIN EN ISO 4762 fillister head screws, blackened, smooth-headed,
permitted size and shape variance in accordance with DIN ISO 4759, Part 1, product
class A.
Important
Use a screw locking device (medium strength, e.g. LOCTITE No. 242) to glue the screws
into the counter thread to exclude pre-stressing loss due to screw slackening, if alternating
loads are to be expected.
3. Fasten all screws with the specified torque
(Table 4.1 on page 14).
4. There are tapped holes on the rotor for further mounting. Also use screws of property
class 10.9 or 12.9, and fasten with the torque specified in Table 4.1.
Important
Use a screw locking device (medium strength, e.g. LOCTITE No. 242) to glue the screws
into the counter thread to exclude pre-stressing loss due to screw slackening, if alternating
loads are to be expected.

1. Undo and remove the bolted connections (M5) on the upper antenna segment.
There are fan type lock washers between the antenna segments: Make sure that they do
not get lost.
2. Use an appropriate base plate to install the stator housing in the shaft train so that there
is sufficient opportunity for horizontal and vertical adjustments. Do not fully tighten the
bolts yet.
Tip
If your transducer has a sensor for the reference signal, you should only fit the
upper antenna segment after step 5.
3. Now use two hexagon socket screws to mount the upper antenna segment removed
in Point 1 on the lower antenna segment.
Make sure that the two fan type lock washers are inserted between the antenna
segments (these ensure that there is a defined contact resistance)!
