Pivoting Support for ZUMBACH
ODAC® Laser Gauges
•tIn-line height and width measurement of profiles
•tVery accurate readings, independent 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 perfectly
aligned with the laser beam.
+10°
A twist angle of 1° or less can already cause errors which are
often larger than the specified product tolerance.
-10°
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
Measuring head on the DVW 1
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.
