Optical laser-based sensors from
Micro-Epsilon are reported to be
playing a vital role in inspecting the
quality of manufactured pulleys. The
high speed and high resolution of
the sensor enables the tip diameter of
the pulleys to be measured accurately
and rapidly in two planes.

Measurement technology service
provider QS-Grimm has developed
special purpose testing stations for
the application, comprising four
optoCONTROL 2500 optical
micrometers from Micro-Epsilon.

Two sensors each record the tip
diameter on a plane to the left and
right of the pulley. Due to their ability
to rapidly evaluate the measurement
data in one plane, the diameter of
the tip can be determined accurately
to a resolution of 0.1µm.
