Triangulation Sensors Go 3-D
Noncontact measurement systems improve quality and reduce waste on the production line.
by Dale Greer, Perceptron Inc.
Noncontact measurements determine the quality of a manufacturing process so that it can be controlled. Using laser sensors to gather real-time data throughout the production process helps reduce defects and wasted materials, ensure better overall quality and improve the manufacturing process from startup.
For more than 20 years, triangulation sensors have been installed in in-line automotive assembly stations to gather data on various parts. The same technology has been successfully used to guide robots during auto assembly for almost as many years. What has changed is not so much the technology of the sensor but rather the software and processing of the data, which now makes triangulation sensors more usable than ever...
