of the pointer
Fixed firmly to the housing or the operating element, the pointer shaft with the red pointer is mounted at the centre of the position indicator. The red pointer therefore shows the revolution of the spindle at a ratio of 1 to 1, at the same time turning in the same direction as the spindle. The pendulum is positioned freely on the same pointer shaft, with the pendulum not turning in sync but always held in the same position owing to its force of gravity.
The outstanding feature of pendulum-type position indicators is that the measuring system is fully integrated in the operating element. During installation, they require no further measures on the machine side.
While the red pointer shows the rotary motion of the spindle at a ratio of 1 to 1, the register shows a numerical value matching the axial displacement of the spindle as factor of the thread pitch.
The standard scale has 50 graduation marks without numbers.
