Stahlwille Mechanical calibration device Measuring r.–400N·m for transducers sizes 1-100

measurement possible without moving the point of application of forcethanks to a specially designed force transmission system, mechanical loader No 7791 avoids the risk of the point of force application shifting during the calibration processthe lever below the test rail is actuated in a linear direction by the handwheel acting on a spindlethe linear motion is translated into a rotary movement which acts on the transducerthe torque wrench to be calibrated remains in the same position throughout the calibration processthis prevents measuring errors caused by the point of force application being movedthanks to a low-friction linear ball bearing, the torque wrench is automatically levelled as it is placed in the unita further linear ball bearing ensures the contact with the torque wrench is friction-freethe reduction in lateral forces acting on the transducer and in the friction on the point of contact with the torque wrench results in a corresponding reduction in mismeasurementprotected by national and international patents
