STAHLWILLE Manual calibration device 7791 400Nm for size 1-100 52110091

STAHLWILLE Manual - measurement without shifting the point of force application - thanks to a special force transmission system, the mechanical calibration device no. 7791 avoids a displacement of the force application point during the calibration process- driven by the handwheel, the lever mounted below the test rail is moved linearly by a spindle- the linear movement is converted into a rotary movement which acts on the transducer- the torque wrench to be calibrated remains in a constant position during the entire calibration- this avoids measurement errors, This avoids measurement errors resulting from a shift in the point of application of force- A low-friction ball bushing automatically aligns the torque wrench horizontally- A further ball bushing ensures that the torque wrench is supported without friction- The resulting reduction in lateral forces on the transducer and friction on the torque wrench support leads to a reduction in measurement errors- Protected by national and international patents.
