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.

T10FM

A0894-5.2 enHBM

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).

T10FM

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.

1 Scope of supply

Rotor

Stator

Mounting instructions

Test record

Optional: Speed kit (slotted disc, screwdriver, screw locking device,

screws)

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.
