Reproducible Results

Steinmeyer produced special shafts where the thread was ground in three diameters for basic testing. The idle torque of the nut was measured to detect the preload which resulted in three clearly marked steps. The torque measurement verifies these three preload regions in the prestroke and return stroke.

The findings from these comparisons were unambiguous and reproducible. The evaluation of the sensor signal correlates clearly with the preload regions of the idle torque.

Steinmeyer engineers developed a concept from these fundamentals jointly with ifm.
