•In-line height and width
measurement of profiles
•Very accurate readings, independant of position and twist
The Problem
Non-contact in-line measurement of profile shapes has
always been a problem. Most optical systems using laser
or CCD cameras measure the height of the shadow of the
product that is subject to strong variations, if the
product is not pefectly aligned with the laser beam.
A twist angle of 1° or less can already cause errors which
are often larger than the specified product tolerance.
Most profiles, in particular steel, can not be guided absolutely
parallel, due to their mechanical stiffness and due to required
forces for guiding.

The Solution
The pivoting support DVW 1 is a simple accessory for
some ODAC® laser head models
used for such applications.
With the continuously pivoting motion of the laser heads combined
with the electronic "minimal value detection" of the
relevant dimension, the height (or thickness) will be measured
very accurately in most cases.
The device needs no additional electronics. It is, together with
the laser measuring head, directly powered and controlled by the
respective processor unit.
