Calibration Beams & Weights

Norbar’s Test Beams are designed for the static calibration of Torque Transducers. Ideally suited to Norbar’s transducers, the beams can be employed on other manufacturer’s equipment as well. Torque is generated by the application of a known force at a known radius from the center of rotation of the torque transducer. The beams are designed with square drives machined to the top limit of ISO 2725:1987 which minimizes any play between the beam and the transducer. However, a combination of square drive tolerances, misalignment of fittings and elastic rotation of the transducer shaft inevitably cause the beam to rotate from the horizontal under load. Various calibrated weights sets can be supplied in metric or imperial sizes for use with Norbar calibration beams.

  • Clockwise and counterclockwise operation
  • Compatible with male and female ¼” transducer drives
  • No bearings to cause energy loss during loading
  • Beams balanced to maximize energy transfer to transducer during loading
