Measuring wheels are a very cost-effective way to
use rotary encoders to measure linear motion such
as a cut to length applications. Measuring wheels
are also useful when it is inconvenient to mount the
encoder directly to the motion device. It is common
to have one or two measuring wheels mounted on an
encoder shaft. The two most important factors in selecting
the best measuring wheel for a given application are
the circumference and the surface material. The surface
material must be chosen to give optimal traction without
unduly compromising wear, while the circumference
should be selected to give the best accuracy within
the mounting constraints available.
EPC offers two types of measuring wheels in both
english and metric circumferences. The first type,
Faced Measuring Wheels, has a wide contact
surface with a variety of faced coatings, one of which
will be suitable for nearly every specialized application.
The second, Rubber Insert Measuring Wheels,
uses a replaceable rubber insert, or "spare tire",
that is easier to set up and maintain, and fits most
general-purpose requirements.

and performs better for tracking rough or hard
fibers than the slightly softer 80 urethane material.
