Note:
Position indicators are provided for installation in handwheels. They allow direct readout of set measurement values such as lengths, flow rates, speeds, etc, at a glance.
The measurement values are acquired according to the gravity principle. Conceived for use on horizontal spindles.

The transmission ratio indicates how many spindle rotations (black pointer) are necessary for one rotation of the smaller, red pointer (while the longer, black pointer indicates the rotational movement of the spindle 1:1, i.e., 1 spindle rotation = 1 pointer rotation, the smaller, red pointer carries out only a fraction, defined by the transmission ratio, of the rotational motion).
On request:
– Other transmission ratios
