Optical micrometers for pulley inspection

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.
