Measuring thickness of lumber on a lumber grading line is a common application for Acuity laser sensors.  One of Acuity's preferred sensor integrators, Laser-View Technologies, has integrated a pair of AccuRange 200 laser measurement sensors to create a laser caliper sysem. The system was installed into grading lines to measure thickness as pre-finished boards as they pass through a feed system.  Laser calipers can be used with a single or pair of AccuRange laser displacement sensors to measure average thickness on an automatic grading line.  Alarm outputs are sent to other process equipment when rejected lumber is detected.  This application can also be used to measure thickness of boards or sheets of other building materials liker gypsum board, OSB or metal as they are passed along a conveyor line.  Laser-View Technologies' software is configured to automatically detect the leading and trailing edges of boards. The average of the measurements is displayed and the pass / fail status is indicated by the display colors.  The measurement profile and distribution are also displayed. This information can be archived for ISO 9000 quality control archiving purposes.
