    Torque Sensor Model 8627, 8628, 8632 1.4 Reconstructions and Modifications Each modification of the sensors without our written approval excludes liability on our part. Personnel The installation, assembly, commissioning, operation and the disassembly must be carried out by qualified only. The personnel must have the knowledge and make use of the legal regulations and safety instructions.

  • Page 9: Term Definitions

    Torque Sensor Model 8627, 8628, 8632 2. Term Definitions Terms Measuring side: Shaft connection in which the torque to be measured is applied. Usually this side has the smallest moment of inertia. Dive side: The shaft end on the opposite side of the measuring side with the larger mo- ment of inertia.

  • Page 10: Product Description

    The sensor measures static and dynamic torques. The mounting position of the torque sensor is horizontally or vertically. Caution: It is to be differentiated between measuring side and drive side, see data sheet of the sensor on the burster website. Torsion Body Mechanical Setup The sensor do not contain rotary parts.

  • Page 11: Mechanical Assembly

    Torque Sensor Model 8627, 8628, 8632 Mechanical Assembly Caution: During the assembly inadmissibly large forces may not act on the sensor or the couplings. At small torque (< 20 Nm) connect the sensor electrically during the assembly and observe the signal, the measurement signal ma not exceed the limit values.

  • Page 12: Flange Connection

    Torque Sensor Model 8627, 8628, 8632 Flange Connection Before the assembly, flanges must be cleaned with dissolver (e.g. acetone), no foreign particles may adhere to them. The surface of the flange must indicate a evenness of at least 0.02 mm.

  • Page 14: Cable

    Caution: Depending on bridge resistance and wire cross section, the measur- ing cable length enters into the characteristic value of the sensor. Therefore order the sensor together with the extension cable and the calibration at burster praezisionsmesstechnik gmbh & co kg.

  • Page 15: Measuring

    Torque mains clockwise or clockwise torque if the torque acts clockwise when facing the shaft end. In this case a positive electrical signal is obtained at the output. Torque sensors by burster praezisionsmesstechnik gmbh & co kg can measure both, clockwise and counter-clockwise direction.

    The calibration of the sensor is carried out according to the guidelines of the DKD/DAkkS. The surveillance of the calibrating-laboratory takes place by the DKD/DAkkS. At this calibration, the uncertainly of measurement of the torque sensors is determined. Further information can be obtained burster praezi- sionsmessgeräte gmbh & co kg. 11.3 RE-Calibration The re-calibration of the torque sensor should be carried out after 26 months.
