compact industrial PC with high working
reliability; highly developed Steelmaster
software; sophisticated mechanics and
protection system; and close to zero
maintenance.
Profilemaster provides accurate in-line
profile measurement using ‘light section’
principle and machine vision. Between one
and six laser/camera modules measure the
cross-section of the moving profile, and
a powerful PC-based processor adds the
partial pictures of the cameras made up of
straight lines and radii together to yield the
momentary cross-section of the profile.
All relevant dimensions, such as width,
height, angle and radii, are added together
to form the full cross-sectional picture. The
nominal values for the profile can be directly
imported from the CAD construction (as a
DXF file), which allows easy and problem-
free programming. Changes in speed and
twist within normal limits have no affect on
the measurement.
The combination of one to six laser/
camera modules allows the measurement
of virtually all shapes, achieving an optimal
measurement result with the smallest
possible number of laser/camera modules.
The Odac Trio system provides three-
axis laser measurement
of diameter and ovality.
Conventional two-
axis instruments with
laser or CCD can only
provide approximate
values for minimum
OD, maximum OD and
ovality. The mean value
(X+Y/2) is influenced
by the orientation of the
product ovality within
the measuring field. The
Trio concept solves such
problems.
Advantages include
three synchronised
measurement axes on
a single plane; compact
design; reliable detection
of out-of-round condition,
regardless of the orientation of the product
ovality; detection of any deviation from
roundness of oval and out-of-round with
polygonal shape (multi-lobe). The system
yields accurate mean value, regardless of
the orientation of the product ovality, and
computes accurate values of circumference
and cross section.
Available interfaces includeRS-232/-422/-
485, Profibus DP, Ethernet, and J standard
for USYS processors from Zumbach.
