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.

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. The values stated in the specificationsmust 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 load‐carrying 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 “Load‐carrying 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

A3452-5.0 en/de HBM

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 fail‐safe. 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 (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 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 system startup 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.

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 via an

AMR sensor and a magnetic ring. The magnetic ring for measurement of rota-

tional 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 meas-

uring 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 speed sensor.
