Son fonctionnement est soumis aux deux conditions suivantes : (1)cet appareil ne doit pas causer d’interférence et (2) cet appareil doit acceptertoute interférence, notamment les interférences qui peuvent affecter sonfonctionnement.NOTEAny changes or modification not expressly approved by the party responsiblefor compliance could void the user’s authority to operate the device. Wherespecified additional components or accessories elsewhere defined to be usedwith the installation of the product, they must be used in order to ensure com-pliance with FCC regulations.Appropriate useThe T12 torque flange is used exclusively for torque, angle of rotation andpower measurement tasks within the load limits stipulated in thespecifications. 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 compliancewith the specifications and with the safety requirements and regulations ofthese mounting instructions. It is also essential to observe the applicable legaland safety regulations for the application concerned. The same applies to theuse of accessories.The torque flange is not intended for use as a safety component. Please alsorefer to the “Additional safety precautions” section. Proper and safe operationrequires proper transportation, correct storage, siting and mounting, andcareful operation.Load carrying capacity limitsThe data in the technical data sheets must be complied with when using thetorque flange. In particular, the respective maximum loads specified mustnever be exceeded. For example, the values stated in the specifications mustnot be exceeded 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.
7T12A1979−10.0 en HBMUse as a machine elementThe torque flange can be used as a machine element. When used in thismanner, it must be noted that, to favor greater sensitivity, the transducer is notdesigned with the safety factors usual in mechanical engineering. Please referhere to the section “Load carrying capacity limits” and to the specifications.Accident preventionAccording to the prevailing accident prevention regulations, once thetransducers have been mounted, a covering agent or cladding has to be fittedas follows:The covering agent or cladding must not be free to rotate.The covering agent or cladding should prevent squeezing or shearing andprovide protection against parts that might come loose.Covering agents and cladding must be positioned at a suitable distance orbe so arranged that there is no access to any moving parts within.Covering agents and cladding must still be attached, even if the movingparts of the torque flange are installed outside people’s movement andworking range.The only permitted exceptions to the above requirements are if the torqueflange is already fully protected by the design of the machine or by existingsafety precautions.Additional safety precautionsThe torque flange cannot (as a passive transducer) implement any(safety-relevant) cutoffs. This requires additional components andconstructive measures, for which the installer and operator of the plant isresponsible. The electronics conditioning the measurement signal should bedesigned so that measurement signal failure does not subsequently causedamage.The scope of supply and performance of the transducer covers only a smallarea of torque measurement technology. In addition, equipment planners,installers and operators should plan, implement and respond to safetyengineering 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 instructionsThe torque flange corresponds to the state of the art and is reliable.Transducers can give rise to residual dangers if they are incorrectly operatedor inappropriately mounted, installed and operated by untrained personnel.Every person involved with siting, starting-up, operating or repairing a torqueflange must have read and understood the mounting instructions and inparticular the technical safety instructions. The transducers can be damaged
T128A1979−10.0 enHBMor destroyed by non-designated use of the transducer or by non-compliancewith the mounting and operating instructions, these safety instructions or anyother applicable safety regulations (BG safety and accident preventionregulations), when using the transducers. Transducers can break, particularlyin the case of overloading. The breakage of a transducer can also causedamage 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 thesafety instructions or specifications in the mounting and operating instructionsare ignored, it is also possible that the transducer may fail or malfunction, withthe result that persons or property may be adversely affected (due to thetorques acting on or being monitored by the torque flange).Conversions and modificationsThe transducer must not be modified from the design or safety engineeringpoint of view except with our express agreement. Any modification shallexclude all liability on our part for any damage resulting therefrom.Selling onIf the torque flange is sold on, these mounting instructions must be includedwith the torque flange.Qualified personnelQualified personnel means persons entrusted with siting, mounting, startingup and operating the product, who possess the appropriate qualifications fortheir function.This includes people who meet at least one of the three followingrequirements:−Knowledge of the safety concepts of automation technology is arequirement and as project personnel, you must be familiar with theseconcepts.−As automation plant operating personnel, you have been instructed how tohandle the machinery.

T1212A1979−10.0 enHBM4 ApplicationThe T12 digital torque transducer acquires static and dynamic torque atstationary or rotating shafts, determines the rotational speed or angle ofrotation while specifying the direction of rotation, and calculates the power. Itis designed for:highly dynamic torque measurements when testing the power andfunctionality of engines and compound setshigh-resolution rotational speed and angle of rotation measurementsfast, dynamic power measurements on engine and transmission test rigsand roll test standsDesigned to work without bearings and with contactless digital signaltransmission, the torque measuring system is maintenance-free.The torque transducer is supplied for nominal (rated) torques of 100 Nm to10 kNm. Depending on the nominal (rated) torque, maximum rotationalspeeds of up to 18 000 rpm are permissible.The T12 torque transducer is reliably protected against electromagneticinterference. It has been tested according to harmonized European standardsand complies with US and Canadian standards. The product carries the CEmark and / or FCC label.

A further scaling of the frequencyoutput and the analog output is then possible.ImportantScaling at position  (see Fig. 4.1) changes the internal calibration of thetorque transducer.The rotational speed signal can be filtered and also scaled for analog output.The angle of rotation signal, the power signal (low-pass filter LP) and thetemperature signal are only available on fieldbuses.The torque signal and the rotational speed signal can be filtered via two lowpasses connected in series, with filter outputs also being available separately.The scaled, unfiltered torque signal is used to calculate power. The resultant,highly-dynamically calculated power signal is filtered via a further low pass.
T1214A1979−10.0 enHBMFor settings over 100 Hz (torque low-pass filter 1 only), phase delaycompensation is run for the angle of rotation signal. This ensures that torqueand angle of rotation values that are measured simultaneously are also outputsimultaneously.Two pulse strings, offset by 90, are also available as RS422-compatiblesignals for rotational speed and angle of rotation.6 Structure and mode of operationThe torque transducer comprises two separate parts: the rotor and the stator.Strain gages (SGs) are installed on the rotor for torque calculation.Carrier-frequency technology (19.2 kHz carrier frequency) is used for the SGevaluation. The rotor temperature is acquired at two measuring points andaveraged.The electronics for transmitting the bridge excitation voltage and themeasurement signal are located centrally in the rotor. The coils for thecontactless transmission of excitation voltage and measurement signal arelocated on the outer circumference of rotor side A. The signals are sent andreceived by a transmitter head. The transmitter head is mounted on the stator,which houses the electronics for voltage adaptation and signal conditioning.Connector plugs for inputs and outputs (for pin assignment, see Chapter 9.3)are located on the stator. The transmitter head encloses the rotor over asegment of about 120 and should be mounted concentrically around the rotor(see Chapter 7).In the case of the rotational speed measuring system option, the rotationalspeed sensor is mounted on the stator and the customer attaches theassociated slotted disc on the rotor. Rotational speed measurement is optical,using the infrared transmitted light principle.

T1216A1979−10.0 enHBM7 Mechanical installation7.1 Important precautions during installationNOTEA torque flange is a precision measuring element and therefore needs carefulhandling. Dropping or knocking the transducer may cause permanentdamage. Make sure that the transducer cannot be overloaded, including whileit is being mounted.Handle the transducer with care.Check the effect of bending moments, critical rotational speeds and naturaltorsional vibrations, to prevent the transducer being overloaded byresonance sharpness.Make sure that the transducer cannot be overloaded.WARNINGThere is a danger of the transducer breaking if it is overloaded. This cancause danger for the operating personnel of the system in which thetransducer is installed.Implement appropriate safety measures to avoid overloads and to protectagainst resulting dangers.Use a threadlocker (medium strength, e.g. LOCTITE) to glue the screwsinto the counter thread to exclude prestressing loss due to screwslackening, in the event of alternating loads.Comply with the mounting dimensions to enable correct operation.An appropriate shaft flange enables the T12 torque flange to be mounteddirectly. It is also possible to mount a joint shaft or relevant compensatingelement directly on the rotor (using an intermediate flange when required).Under no circumstances should the permissible limits specified for bendingmoments, lateral and longitudinal forces be exceeded. Due to the T12 torqueflange’s high torsional stiffness, dynamic shaft train changes are kept to aminimum.
17T12A1979−10.0 en HBMImportantEven if the unit is installed correctly, the zero point adjustment made at thefactory can shift by up to approx. 3% of the sensitivity. If this value isexceeded, we advise you to check the mounting conditions. If the residualzero offset when the unit is removed is greater than 1% of the sensitivity,please send the transducer back to the Darmstadt factory for testing.7.2 Conditions on siteThe T12 torque transducer is protected to IP54 according to EN 60529.Protect the transducer from coarse dirt, dust, oil, solvents and moisture.During operation, the prevailing safety regulations for the security ofpersonnel must be observed (see “Safety instructions”).There is wide ranging compensation for the effects of temperature on theoutput and zero signals of the T12 torque transducer (see specifications onpage 56). This compensation is carried out at static temperatures. Thisguarantees that the circumstances can be reproduced and the properties ofthe transducer can be reconstructed at any time.If there are no static temperature ratios, for example, because of thetemperature differences between flange A and flange B, the values given inthe specifications can be exceeded. Then for accurate measurements, youmust ensure static temperature ratios by cooling or heating, depending on theapplication. As an alternative, check thermal decoupling, by means of heatradiating elements such as multiple disc couplings.7.3 Mounting positionThe transducer can be mounted in any position. With clockwise torque, theoutput frequency is 10 to 15 kHz (Option 4, code DF1/DU2: 60 kHz to90 kHz). In conjunction with HBM amplifiers or when using the voltage output,a positive output signal (0 V to +10 V) is present.With counterclockwise torque, the output frequency is 5 kHz to 10 kHz (Option4, code DF1/DU2: 30 kHz to 60 kHz).In the case of the rotational speed measuring system, an arrow is attached tothe head of the sensor to clearly define the direction of rotation. When thetransducer rotates in the direction of the arrow, a positive rotational speedsignal is output.
T1218A1979−10.0 enHBM7.4 Installing the slotted disc (rotational speed measuringsystem only)To prevent damage to the rotational speed measuring system’s slotted discduring transportation, it is not mounted on the rotor. The customer must attachit to the mounting ring before installing the rotor in the shaft train. Themounting ring and the associated rotational speed sensor are alreadymounted at the factory.The requisite screws, a suitable screwdriver and the threadlocker are includedamong the components supplied.Slotted discFastening screw Mounting ringFig. 6.1: Installing the slotted discImportantWhen carrying out the installation, be careful not to damage the slotted disc!Installation sequence1. Push the slotted disc onto the mounting ring and align the screw holes.2. Apply some of the threadlocker to the screw thread and tighten the screws(tightening torque < 0.15 Nm).
19T12A1979−10.0 en HBM7.5 Installing the rotorTipUsually the rotor type plate is no longer visible after installation. This is whywe include with the rotor additional stickers with the important characteristics,which you can attach to the stator or any other relevant test-benchcomponents. You can then refer to them whenever there is anything you wishto know, such as the shunt signal. To explicitly assign the data, theidentification number and the size are engraved on the rotor flange, wherethey can be seen from outside.NOTEMake sure during installation that you do not damage the measuring zonemarked in Fig. 6.2 by using it to support tools, or knocking tools against itwhen tightening screws, for example. This can damage the transducer andproduce measurement errors, or even destroy the transducer.Fastening screwFlange B Identification number and measuring rangeMeasuring zoneFig. 6.2: Screw connections, flange B
T1220A1979−10.0 enHBM1. Prior to installation, clean the plane faces of the transducer flange and thecounter flange.For safe torque transfer, the faces must be clean and free from grease.Use a piece of cloth or paper soaked in solvent. When cleaning, make surethat you do not damage the transmitter coils.2. For the flange B screw connection, use hexagon socket screws DIN ENISO 4762 of property class 10.9 (measuring ranges 3 kN@m to 10 kN@m:12.9) of the appropriate length (depending on the connection geometry, seeTable 6.1).We recommend fillister-head screws DIN EN ISO 4762, blackened,smooth-headed, permitted size and shape variance as per DIN ISO 4759,Part 1, product class A.3. First tighten all the screws crosswise with 80% of the prescribed tighteningtorque (Table 6.1), then tighten again crosswise, with the full tighteningtorque.4. There are relevant tapped holes on flange A for continuing the shaft trainmounting. Again use screws of property class 10.9 (measuring ranges3kNm to 10 kNVm: 12.9), and tighten them with the prescribed moment asspecified in Table 6.1.Fastening screw ZFlange AFastening screw ZFig. 6.3: Screw connections, flange A
21T12A1979−10.0 en HBMImportantUse a threadlocker (medium strength, e.g. LOCTITE) to glue the screws intothe counter thread to exclude prestressing loss due to screw slackening, inthe event of alternating loads.NOTEComply with the maximum thread reach as per Table 6.1.

Screw in the cover plate locking screws and tighten them at 2 N@m.7.7 Installing the statorOn delivery, the stator has already been installed and is ready for operation.There are four tapped holes on the base of the stator housing for mountingthe stator. Externally, two with a metric M6 thread, internally, two with a UNF1/4” thread (closed with a plastic threaded pin).We recommend using two metric thread DIN EN ISO 4762 fillister-headscrews with hexagon sockets of property class 10.9 of the appropriate length(depending on the connection geometry – not included among thecomponents supplied; tightening torque = 14 N@m).TipTo allow the stator to be aligned to the rotor, make sure that repositioning ispossible (e.g. oblong holes).The stator can be mounted radially in any position (an “upside down”installation is possible, for example). You can also install the stator over theprotection against contact (option), see Chapter 7.7.3 .Fig. 6.11: Mounting holes in the stator housing (viewed from below)With the T12/5 kN@m and T12/10 kN@m torque transducers, we recommendadditionally supporting the stator at the protection against contact. Fig. 6.12shows an example of how to attach an angle bracket with a bolt (A) or with athreaded rod (B). Note that in this case, the cover plates cannot be fitted.

37T12A1979−10.0 en HBM9 Electrical connection9.1 General informationDetailed instructions for connecting the T12 to the CAN Bus or thePROFIBUS can be found in the “T12 CAN Bus/PROFIBUS” interfacedescription (in pdf format) on the T12 system CD.To make the electrical connection between the torque transducer and themeasuring amplifier, we recommend using shielded, low-capacitancemeasurement cables from HBM.With extension cables, make sure that there is a proper connection withminimum contact resistance and good insulation. All plug connections orswivel nuts nuts must be fully tightened.Do not route the measurement cables parallel to power lines and controlcircuits. If this cannot be avoided (in cable pits, for example), maintain aminimum distance of 50 cm and also draw the measurement cable into a steeltube.Avoid transformers, motors, contactors, thyristor controls and similarstray-field sources.Consider longer cable of approximately 40cm due to the installation of thewounded core (toroidal core).ImportantTransducer connection cables from HBM with plugs attached are identified inaccordance with their intended purpose (Md or n). When cables areshortened, inserted into cable ducts or installed in control cabinets, thisidentification can get lost or become concealed. If this is the case, it isessential for the cables to be re-labeled!Tape wound core (toroidal core):To suppress high frequencies a tape wound core (toroidal core) on the powercable has to be used. Use at least 3 loops of the cable.
T1238A1979−10.0 enHBM3 loopsFig. 6.21: Installation ExampleIf the core has to be removed for any purpose (e.g. for maintenance), it mustbe replaced on the cable. Use only wounded core (toroidal core) of the correcttype.Type: Vitroperm RModel No.: T60006−22063W517Size: external diameter x internal diameter x height = 63 x 50 x 25The core should be placed as close as possible to the connector. However,prevent stress on the connector due to the extra weight of the cable.NOTEFor US stator Version Option 9, Code U the use of a tape wound core (tor-oidal core) on the power cable (plug 1 or plug3) is mandatory to ensure com-pliance with FCC regulations.ImportantFor US Version Option 9, Code U the use of a tape wound core (toroidal core)on the signal cable is mandatory to ensure compliance with FCC regulations.The cables and plugs for connectors 1, 2 and 3 are compatible with theT10FS torque flange.
39T12A1979−10.0 en HBM9.2 Shielding designThe cable shield is connected in accordance with the Greenline concept. Thisencloses the measurement system (without the rotor) in a Faraday cage. It isimportant that the shield is laid flat on the housing ground at both ends of thecable. Any electromagnetic interference active here does not affect themeasurement signal. Special electronic coding methods are used to protectthe purely digital signal transmission between the transmitter head and therotor from electromagnetic interference.In the case of interference due to potential differences (compensatingcurrents), supply voltage zero and housing ground must be disconnected onthe amplifier and a potential equalization line established between the statorhousing and the amplifier housing (copper conductor, 10 mm2 wirecrosssection).Should differences in potential between the machine rotor and stator causeinterference, because of unchecked leakage, for example, this can usually beovercome by connecting the rotor definitively to ground, by a wire loop, forexample. The stator should be fully grounded in the same way.9.3 Connector pin assignmentAssignment for plug 1:Supply voltage and frequency output signal.6157243Binder 423device plugTop viewPlugpinAssignment ColorcodeD-Sub-plugpin1Torque measurement signal (frequency output;5 V1)/0) wh 132 Supply voltage 0 V; bk 53Supply voltage 18 V  30 V bu 64Torque measurement signal (frequency output;5 V1)V) rd 125Measurement signal 0 V;symmetricalgy 86Shunt signal trigger 5 V  30 V and TEDS fortorquegn 147Shunt signal 0 V; gy 8Shielding connected to housing ground1) RS−422 complementary signals; with cable lengths exceeding 10 m, we recommendusing a termination resistor R=120 ohms between the wires (wh) and (rd).

You can supply one or more torqueflanges within a test bench at the same time. Should the device be operatedon a DC voltage network1), additional precautions must be taken to dischargeexcess voltages.The notes in this section relate to the self-contained operation of the T12without HBM system solutions.The supply voltage is electrically isolated from signal outputs and shunt signalinputs. Connect a separated extra-low voltage of 18 V to 30 V to pin 3 (+) andpin 2 ( ) of plug 1 or 3. We recommend that you use HBM cableKAB 8/00−2/2/2 and the relevant Binder sockets, that at nominal (rated)
T1244A1979−10.0 enHBMvoltage (24 V) can be up to 50 m long and in the nominal (rated) voltagerange, 20 m long (see Accessories, page 88).If the permissible cable length is exceeded, you can feed the supply voltage inparallel over two connection cables (plugs 1 and 3). This enables you todouble the permissible length. Alternatively, install an on-site power supply.If you feed the supply voltage through an unshielded cable, the cable must betwisted (interference suppression). We also recommend that a ferrite elementshould be located close to the connector plug on the cable, and that the statorshould be grounded.ImportantThe instant you switch on, a current of up to 4 A may flow and this may switchoff power supplies with electronic current limiters.1) Distribution system for electrical energy with greater physical expansion (over several test benches, forexample) that may possibly also supply consumers with high nominal (rated) currents.
45T12A1979−10.0 en HBM10 Shunt signalThe T12 torque transducer supplies a shunt signal, at either 50% or 10% ofthe nominal (rated) torque, as selected. Activate this function via the T12Assistant or the shunt signal trigger on plug 1 or plug 3 (see Section 9.3). Thelast shunt selected in the T12 Assistant is then triggered.The internal signal conditioning may cause a delay in triggering of about 5seconds.To obtain stable conditions, we recommend activating the shunt signal onlyonce the transducer has been warming up for 15 minutes.The framework conditions for reproducibility (e.g. the mounting conditions)must be established in order to reproduce the measured values in themanufacturing certificate.ImportantThe transducer should not be under load when the shunt signal is beingmeasured, as the signal is applied additively.After about 5 minutes, the shunt signal is automatically deactivated.
T1246A1979−10.0 enHBM11 Load-carrying capacityNominal (rated) torque can be exceeded statically up to the limit torque. If thenominal (rated) torque is exceeded, additional irregular loading is notpermissible. This includes longitudinal forces, lateral forces and bendingmoments. Limit values can be found in the “Specifications” chapter (Chapter15, page 56).Measuring dynamic torqueThe torque transducer is suitable for measuring static and dynamic torques.The following apply to the measurement of dynamic torque:The T12 calibration run for static measurements is also valid for dynamictorque measurements.The natural frequency f0 of the mechanical measuring system depends onthe moments of inertia J1 and J2 of the connected rotating masses and theT12’s torsional stiffness.Use the equation below to approximately determine the natural frequency f0 ofthe mechanical measuring system:f0+12p·cT·ǒ1J1)1J2ǓǸf0= natural frequency in HzJ1, J2= mass moment of inertia in kgm2cT= torsional stiffness in Nm/radThe maximum oscillation width is 200% (measuring range 3 kN@m to 10kN@m: 160%) of the typical nominal (rated) torque for the T12 (see“Specifications”, page 56) The oscillation width must lie between themaximum upper and lower torques of the defined loading range.

47T12A1979−10.0 en HBM12 TEDSTEDS (Transducer Electronic Data Sheet) allows you to store the transducerdata (characteristic values) in a chip, that can be read out by a connectedmeasuring instrument.There are two TEDS blocks in the T12 digital torque transducer:TEDS 1 (torque): a choice of voltage sensor or frequency sensor/pulsesensorTEDS 2 (rotational speed/angle of rotation): frequency sensor/pulse sensorThe data are written automatically into the TEDS blocks by the T12 Assistant,when the parameters are stored. The same menu is used to select whetherthe device should be presented as a voltage sensor or as a frequency sensoror as a frequency or pulse sensor. A template is also stored, which providesthe conversion factors for the different physical units.The T12 is a transducer, that is to say, the T12 does not read the TEDSblocks, it only writes them. (We therefore strongly advise against editing thevalues with the HBM TEDS Editor, for example!)You can read the data of the TEDS block with the TEDS Editor.ImportantTo ensure that the data of the TEDS blocks correspond to the properties ofthe T12 torque transducer, you must not overwrite the information from themeasuring amplifier.For more information on TEDS, look in the T12 Assistant online Help.Content of the TEDS memory as defined in IEEE 1451.4The information in the TEDS memory is organized into areas, whichare prestructured to store defined groups of data in table form.Only the entered values are stored in the TEDS memory itself.
