    PTB calibration certificate in accordance with DIN 51 309 or EA 10/14: Class 0.5 Application The T10FH torque flange records static and dynamic torque on fixed or rotat ing shafts and also return RS422 signals with direction of rotation information to determine the speed.

  • Page 10: Structure And Mode Of Operation

    T10FH Structure and mode of operation The torque flange (Option 2, code N) consists of two separate parts: the rotor and the stator. The rotor comprises the measuring body and the signal transmission ele ments. Strain gages (SGs) are mounted on the measuring body. The rotor electronics for transmitting the 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 T10FH torque flange to be mounted directly. It is also possible to directly mount a joint shaft or relevant compen sating elements on the opposite flange (using an intermediate flange when re quired).

    T10FH 4.1 Conditions on site The T10FH torque flange is protected to IP54 according to EN 60529. Protect the transducer from coarse dirt, dust, oil, solvents and moisture. During opera tion, the prevailing safety regulations for the security of personnel must be ob served (see "Safety Instructions").

    1. Remove the top layer of foam packaging. Fig. 4.1: T10FH packaging 2. Fasten two equal−length ropes of sufficient bearing strength to the eye bolts (each of the two ropes must be able to bear the full weight of the ro tor) and hoist the rotor out of its packaging with the crane (see Fig.
  • Page 16 T10FH Fig. 4.2: Hoist the rotor out of its packaging 3. Place the rotor onto a clean and stable base. 4. Remove one of the eyebolts. 5. Carefully lift the rotor until it hangs freely. 6. Carefully tilt the rotor by lowering it over the flange edge until it rests hori zontally on both outer flange surfaces (see Fig.

    T10FH 4.6 Installing the stator On delivery, the stator has already been fitted ready for operation. The an tenna segments have to be separated for installation. 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 22 T10FH 4. Align the antenna and rotor so that the antenna encloses the rotor coaxi ally. Please observe the permissible alignment tolerances stated in the specifications. 5. Now fully tighten the screw fitting of the stator housing. 6. Make sure that the gap in the lower antenna segment area is free of electrically conductive foreign bodies.

    T10FH 4.7 Installing the clamp fixture Depending on the operating conditions, the antenna ring may be excited to vi brate. 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.

    Avoid transformers, motors, contactors, thyristor controls and similar stray− field sources. CAUTION 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.

    Option 3, SU2 torque transducers are only intended for operation with a DC supply voltage (separated extra−low voltage). They must not be con nected to older HBM amplifiers with square−wave excitation.
