STAHLWILLE Mechanical Base Unit

Measurement possible without moving the point of application of force
- Thanks to a specially designed force transmission system, mechanical loader No 7791 avoids the risk of the point of force application shifting during the calibration process.
- The lever below the test rail is actuated in a linear direction by the handwheel acting on a spindle.
- The linear motion is translated into a rotary movement which acts on the transducer.
- The torque wrench to be calibrated remains in the same position throughout the calibration process.
- This prevents measuring errors caused by the point of force application being moved.
- Thanks to a low-friction linear ball bearing, the torque wrench is automatically levelled as it is placed in the unit.
- a further linear ball bearing ensures the contact with the torque wrench is friction-free.
- The 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 mismeasurement.
