  • Page 8 T10FM 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 9: Scope Of Supply

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

  • Page 10: Structure And Mode Of Operation

    T10FM 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.

    T10FM 4.1 Conditions on site T10FM torque flanges are protected to IP54 according to EN 60529. They must be protected against coarse dirt particles, dust, oil, solvents and humidity. During operation, the prevailing safety regulations for the security of personnel must be observed (see “Safety instructions").

    T10FM 4.4 Preparing for the rotor mounting IMPORTANT The rotor is very heavy (depending on measuring range: 26 kg ... 60 kg)! Use a crane or other suitable lifting equipment to lift it out of its packaging and install it.
  • Page 16 T10FM 1. Lift the rotor out of the packaging, rotate horizontally by 10_, so that flange B is pointing upwards (see Fig. 4.2). Flange B Fig. 4.2: Rotating the rotor 2. Place the rotor carefully onto a clean and stable table.

Again use screws of property class 10.9 and tighten them with the prescribed torque, as specified in Table 4.1. IMPORTANT With alternating loads, use a screw locking device to cement the connecting screws into place! Guard against contamination from varnish fragments.

  • Page 20: Installing The Stator

    T10FM 4.6 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 T10FM 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

    T10FM 4.7 Installing the clamp fixture Depending on the operating conditions, oscillations may be induced in the antenna ring. This effect depends 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 with extension is enclosed with the torque flange enabling the antenna ring to be supported.
  • Page 23 T10FM Support supplied by the customer, e.g. threaded rod Clamp fixture Extension Fan‐type lock washers Antenna segments Fig. 4.7: Installing the clamp fixture Important Use, e.g. plastic as the material. Do not use metallic material as this can affect the function of the antenna (signal transmission).

  • Page 24: Fitting The Slotted Disc (Speed Measuring System)

    T10FM 4.8 Fitting the slotted disc (speed measuring system) To prevent damage to the speed measuring systems' slotted disc during transportation, it is not mounted on the rotor. Before installing the rotor in the shaft run, the customer must attach it to the intermediate flange. The intermediate flange and the associated speed sensor are already mounted at the factory.

  • Page 25: Aligning The Stator (Speed Measuring System)

    T10FM 4.9 Aligning the stator (speed measuring system) The stator can be mounted in any position (for example, “upside down" installation is possible). For perfect measuring mode, the slotted disc of the speed measuring system must rotate at a defined position in the sensor pickup.
  • Page 26 T10FM NOTE To attach the stator, we recommend the use of M6 screws with plain washers (width of oblong hole, 9 mm). This size of screw guarantees the necessary travel for alignment. 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.

  • Page 27: 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 28: Connector Pin Assignment

    IMPORTANT These torque flanges are only intended for operation with a DC supply voltage. They must not be connected to older HBM amplifiers with square‐wave excitation. This could lead to the destruction of the connection board resistances or other errors in the measuring amplifiers (the torque flange, on the other hand, is protected and once the proper connections have been re‐established, is ready for operation...

    Connect a separated extra‐low voltage of 18 V...30 V to pin 3 (+) and pin 2 ( ) of connectors 1 or 3. We recommend that you use HBM cable KAB 8/00-2/2/2 and the relevant Binder sockets, that at nominal (rated) voltage (24 V) can be up to 50 m long and in the nominal voltage range, 20 m long (see Accessories, page 45).

  • Page 31: Calibration Signal

    T10FM Calibration signal The T10FM 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.
