  • Page 7: Application

    T10F Application The T10F Torque Flanges measure static and dynamic torques on stationary or rotating shafts. Due to their extremely short design they enable very compact test arrangements to be used. They offer a very wide range of applications. In addition to conventional test-rig applications (motor, roller and gear test-rigs) new solutions for torque measurements partly integrated into the machines are possible.

  • Page 8: Design And Function

    T10F Design and function Strain gauges (S/G) have been mounted on the measuring body. The rotor electronics for bridge-excitation-voltage and measuring-signal transmission is located centrically in the flange. The transmitter coils for the non-contact transmission of excitation voltage and measuring signal are located on the measuring body’s outer circumference.

  • Page 9: Mechanical Installation

    An appropriate shaft flange enables the T10F Torque Flanges to be mounted directly. The adapter flange enables direct mounting of a cardan shaft or corresponding corrector elements (if necessary, via intermediate flange).

  • Page 10: Conditions At The Site Of Installation

    T10F Conditions at the site of installation The T10F Torque Flanges are protected to IP54 according to EN 60 529. The measuring hubs must be protected from dirt, dust, oil, solvants and humidity. During operation, the prevailing safety regulations for the security of personnel must be observed (see ”Notes on safety”).

  • Page 11: Installation Possibilities

    T10F 3.3 Installation possibilities On principle, there are two possibilities for torque-flange mounting: with antenna ring complete or disassembled. We recommend to proceed as described in chapter 3.3.1. If installation according to 3.3.1 is not possible, the stator must be disassembled. For this, do in any case observe the notes on antenna-segment mounting (see ”Installing the stator”).

    T10F 3.4 Installing the rotor NOTE In general, the rotor type-plate will no longer be visible after installation. Therefore, additional adhesive labels including the major characteristics have been supplied; they can be fixed on the stator or other relevant test-rig components thus enabling required data such as e.g. the calibration signal to be read off at any time.
  • Page 15 T10F 2. Use eight DIN912 hexagon-socket screws, property class 10.9 (measuring range 10kNm: 12.9), of the appropriate length (depending on the connection geometry, see Tab. 3.1) to screw-fasten the measuring body. We recommend, particularly for 50Nm, 100Nm and 200Nm situations, fil-...
  • Page 16 T10F CAUTION With alternating loads, use screw locking device to glue into place the connection screws. Guard against contamination from varnish frag- ments. Do in any case observe the maximum thread reach specified in Tab. 3.1. Otherwise, considerable measurement errors might occur or the transducer might suffer damage.

  • Page 17: Installing The Stator

    T10F 3.5 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 installation. If your application does not require stator disassembly, proceed as described in sections 2., 6., 7.

  • Page 22: Matching To The Cable Length

    T10F 4.1 Matching to the cable length The cable length is limited to 20m because of the transmission method used between the rotor and the stator. If you are using a long connecting cable, you must match the stator electronics. There are three switches in the stator housing for this.

  • Page 23: Calibration

    T10F 4.2 Calibration The T10F Torque Flanges supply an electrical calibration signal that can be called from the amplifier. The excitation voltage is increased by pressing the appropriate key on the amplifier. The torque flange generates a calibration signal of about 50% of the nominal torque. The precise value is specified on the type plate.

  • Page 24: Electrical Connection Stator B

    T10F Electrical connection stator B Stator B has the identifying order number K--T10F... (see page 35). The stator housing has several 7--pin Binder 723 device plugs which are assigned in ac- cordance with the option selected. The supply voltage and the calibration signal of plugs 1 and 3 are direct-- coupled via multifuses (automatically resetting fuses).

  • Page 25: Supply Voltage

    Connect a protective low voltage of 18V ...30V to pin 3 (+) and pin 2 ( ) of plug 1 or 3. We recommend the use of HBM connection cable KAB 139A, which may be up to 50m long for the rated voltage (24V) and 20m long within the rated voltage range.

  • Page 26: Calibration

    T10F CAUTION At the instant of switching on, a current of up to 2A may flow and this may switch off power packs with electronic current limiters. 5.2 Calibration NOTE The measurement flange should not be under load when the calibration signal is being measured, since the calibration signal is mixed additively.

    T10F ™5V asymmetrical symmetrical Fig.5.1: Solder bridges for shifting the frequency output voltage 5.4 Setting up zero point If you have a torque measurement flange with the voltage output option, you can remove the identification plate to gain access to two potentiometers. You can use the zero point potentiometer to correct certain zero point variances.

  • Page 28: Functional Testing

    T10F 5.5 Functional testing If it is suspected that the torque measurement flange is not working correctly, the identification plate can be removed so that testing can be carried out. If the LED is shining, the rotor and stator are properly aligned and there is no in- terference with the transmission of measuring signals.
