Oscillating in-line height and width measurement solutions for profiles

DVW / DVO: 
In-line height and width measurement of profiles.
Very 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 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 Solutions:

1. DVW 1 - Pivoting Support for ODAC® Laser Gauges
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.

2. DVO 2 - Oscillating Device For ODAC® Laser Gauges (in the picture on top right)
The oscillating device DVO 2 is a simple accessory for some ODAC® laser head models used for such applications.
With a 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. The DVO 2 is an autonomous unit and can directly be connected to the mains, therefore it does not require an external control unit. The data acquisition, processing and display can be carried out via a processor of ZUMBACH's USYS series or via the CI 1J/RS-RS, -DP or -EN computer interface through a higher level computer system.
