• 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.
