Measuring Wheels
In order to avoid errors when using mea-
suring wheel actuation, it is important
that the slip is kept as low as possible.
When choosing a profile (surface struc-
ture), special attention must be given to
the properties the material being mea-
sured, such as elasticity, thickness and
interaction resistance. Slippage is also
influenced by the width of the contac-
ting measuring wheel, the pressure of
contact, the tensile stress in the mate-
rial that is being measured and the angle
of wrap. The angle of wrap should be as
large as possible. Wheel bodies are made
of cast metal or plastics (see designa-
tion).
The position of the measuring wheel
should be chosen such that the material
moves away from the bearing of the sen-
sor.
Use the following measuring wheels for
different transmission ratios of counters:
