Measurement without displacement of the force application point
Due to a special force transmission system, the mechanical calibration device no. 7791 avoids a displacement of the point of application of force 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 spanner to be calibrated remains constant in its position during the entire calibration process
in this way, measurement errors resulting from a shift of the point of application of the force are avoided
the torque spanner is automatically aligned horizontally by a low-friction ball bushing
another ball bushing ensures friction-free support of the torque wrench
the resulting reduction of the transverse forces on the transducer and the friction on the torque wrench support leads to a reduction of the measuring errors.
