  • Page 9 T10FS 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.

  • Page 10: Torque Flange Versions

    T10FS Torque flange versions In the case of option 2 “Electrical configuration", the T10FS torque flange exists in versions KF1, SF1 and SU2. The difference between these versions lies in the electrical inputs and outputs on the stator, the rotors are the same for all the versions of a measuring range.

  • Page 11: Application

    T10FS Application T10FS torque flanges record static and dynamic torque on fixed or rotating shafts and also return RS-422 signals with direction of rotation information to determine the speed. With an optical speed measuring system, a reference pulse can also be output with the speed pulses. Test beds can be extremely compact because of the short construction of the measurement flanges.

  • Page 12: Structure And Mode Of Operation

    T10FS Structure and mode of operation Torque flanges consist of two separate parts: the rotor and the stator. The rotor comprises the measuring body and the signal transmission elements. Strain gauges (SGs) are mounted on the measuring body. The rotor electronics for transmitting the bridge excitation voltage and the measurement signal are located centrally in the flange.

    (medium strength) to exclude prestressing loss due to screw slackening. An appropriate shaft flange enables the T10FS torque flanges 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).

  • Page 14: Conditions On Site

    The measurement flange can be mounted in any position. With clockwise torque, the output frequency is 10 kHz to 15 kHz. With HBM amplifiers or with the “voltage output" option, a positive output signal (0 V ... +10 V) is present.

  • Page 15: Installation Options

    T10FS 4.3 Installation options In principle, there are two possibilities for torque flange mounting: with the antenna ring complete or dismantled. We recommend mounting as described in Chapter 4.3.1. If installation in accordance with 4.3.1 is not possible (e.g. in the case of subsequent stator replacement or mounting with a speed measuring system), you will have to dismantle the antenna ring.

  • Page 18: Mounting The Rotor

    T10FS 4.4 Mounting the rotor Additional installation notes for the speed measuring system can be found in Chapter 4.7, Page 24. NOTE 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.
  • Page 19 T10FS 2. For the bolted rotor connection, use eight DIN EN ISO 4762 property class 10.9 hexagon socket screws (measuring range w 3 kNVm: 12.9) of a suitable length (dependent on the connection geometry). We recommend fillisterhead screws DIN EN ISO 4762, blackened, smoothheaded, permitted size and shape variance as per DIN ISO 4759, Part 1, product class A.

  • Page 20: Installing The Stator

    T10FS 4.5 Installing the stator On delivery, the stator has already been installed and is ready for operation. The antenna segments can be separated from the stator, for example, for maintenance or to facilitate stator mounting. To stop you modifying the center alignment of the segment rings opposite the base of the stator, we recommend that you separate only one antenna segment from the stator.
  • Page 21 T10FS 1. Loosen and remove the screw fittings (M5) on one antenna segment. Make sure that the fan‐type lock washers are not lost! 2. Use an appropriate base plate to install the stator housing in the shaft train so that there is sufficient possibility for horizontal and vertical adjustments.

  • Page 22: Installing The Clamp Fixture

    T10FS 4.6 Installing the clamp fixture Depending on the operating conditions, oscillations may be induced in the antenna ring. This effect is dependent on  the speed  the antenna diameter (depends in turn on the measuring range)  the design of the machine base To avoid vibrations, a clamp fixture is enclosed with the torque flange enabling the antenna ring to be supported.

Do not use metallic material as this can affect the function of the antenna (signal transmission).

    T10FS 4.7 Mounting the slotted disc (optical speed measuring system) To prevent the slotted disc of the optical speed measuring system being damaged in transit, it is not mounted on the rotor in the case of measurement flanges with option 2, code L (nominal (rated) speed 8000 min 15000 min ).

  • Page 25: Fitting The Mounting Elements (Speed Measuring System)

    T10FS 4.8 Fitting the mounting elements (speed measuring system) Three mounting elements with screws are included with the torque flange to prevent the speed sensor being damaged during installation. The mounting elements hold the rotor centrally in the antenna ring, making installation easier and safer.

  • Page 26: Fixing The Mounting Elements

    T10FS 4.8.1 Fixing the mounting elements 1. Place the rotor with the identification plate upward on a flat base. For the optical speed measuring system only: Hold the stator at a slight slant and push it over the rotor until the slotted disc is located in the optical sensor (Step A, Fig.
  • Page 27 T10FS 4. Fasten the base retaining screws; only tighten them gently at first, so that the mounting elements do not get jammed. 5. Remove the mounting elements (if a mounting element should get jammed, try to move it to the left or right).

    T10FS 4.9 Aligning the stator (speed measuring system) The stator can be mounted in any position (for example, “upside down" installation is possible). For measuring mode to operate perfectly, the speed sensor (pole ring/slotted disc) of the speed measuring system must be positioned at a defined point to the sensor.

    T10FS 4.9.2 Optical speed measuring system Axial alignment There are markers in the optical sensor for axial alignment (orientation lines). When installed, the slotted disc should be exactly above these alignment lines. Divergence of up to "2 mm is permissible in measuring mode (total of static and dynamic shift).
  • Page 33 T10FS Radial alignment The rotor axis and the optical axis of the speed sensor must be along a line at right angles to the stator platform. A vertical marker line on the head of the sensor serves as an orientation guide.

  • Page 34: Electrical Connection

    Avoid transformers, motors, contactors, thyristor controls and similar stray‐field sources. IMPORTANT Transducer connection cables from HBM with attached connectors are identified in accordance with their intended purpose (Md or n). When cables are shortened, inserted into cable ducts or installed in control cabinets, this identification can get lost or become concealed.

  • Page 35: Shielding Design

    T10FS 5.2 Shielding design The cable shield is connected in accordance with the Greenline concept. This encloses the measurement system (without the rotor) in a Faraday cage. It is important that the shield is laid flat on the housing ground at both ends of the cable.

    Connect a separated extra‐low voltage of 18 V ... 30 V to pin 3 (+) and pin 2 ( ) of connector 1 or 3. We recommend that you use HBM cable KAB 8/00‐2/2/2 and relevant Binder sockets, that at nominal (rated) voltage (24 V) can be up to 50 m long and in the nominal (rated) voltage range, 20 m long (see Accessories, Page 66).
  • Page 41 T10FS If you feed the supply voltage through an unshielded cable, the cable must be twisted (interference suppression). We also recommend that a ferrite element should be located close to the connector plug on the cable, and that the stator should be grounded.

  • Page 42: Calibration

    T10FS Calibration The T10FS torque flange delivers an electrical calibration signal that can be switched at the amplifier end for measurement chains with HBM components. The measurement flange generates a calibration signal of about 50 % of the nominal (rated) torque. The precise value is specified on the type plate. Adjust the amplifier output signal to the calibration signal supplied by the connected torque flange to adapt the amplifier to the measurement flange.

  • Page 43: Calibration Option 2, Code Sf1/Su2

    When voltages are less than 0.7 V, the measurement flange is in measuring mode. Current consumption at nominal (rated) voltage is approx. 2mA and at maximum voltage is approx. 22 mA.
