A customer has an application where they needed to be able to measure the width of a woven material very accurately as it is being made. The customer decided to use the Acuity AP820-80 laser line sensor that projects a laser line of 580 points across a laser line of a 2.5″ length. The laser line is able to measure the width of the tape as it is being moved under the laser line. Accuracies of better than +/- 0.002″ are being made at 100 laser line profiles a second on the moving target.
The AP820 laser line models use a CCD camera that is very good at making difficult target measurements and performs very well on almost all surfaces automatically.
