Pellet
Scanning System PS25C
(Colour
Camera)
The PS25C
inspection system is used to analyse transparent and opaque
pellets. The pellets are inspected with a high-resolution 3-chip
CCD colour camera for impurities, foreign bodies, or colour
deviations as well. The testing material is fed into the
appliance through a hopper. Feeding can be automated by means of
an extension module, e.g. a multi-hopper system or an online
hopper. Moreover, an accurate colour measurement in a special
measurement chamber can be carried out by means of colour
spectrometry CM2 (option). The pellets are conveyed separately
over the inspection zone via a vibrating channel. After the
optical evaluation the contaminated pellets can be separated
into a different container (sorting unit option).
Measuring errors are
eliminated by use of numerous additional optical components. There is no
colour dependency as with many other optoelectronic appliances.
A high level of efficiency is achieved by powerful image processing
software. The synchronisation of the transport system with the image
processing offers a major contribution to the reproducibility of the
measurement results.
Optimum adaptation in
laboratory operations or in measuring stations is a paramount factor in
the quality control. Installation in the bypass guarantees production
monitoring and rapid reaction to any occurrences. The system provides a
variety of individual configurations, which guarantee an improved
adaptation to specific requirements.
The measuring is stored in
a test report to enable future analysis. The recorded images and measured
data can be observed on a screen during the measuring process. The results
can be shown and printed in tables or graphs.
Along with a pure
inspection of pellets the system can also be used to record, file and
document. Each defined deviation is recorded in the measurement protocol
via a multidimensional characteristics vector with an error map.
The system can be adapted
exactly to the respective requirements with the help of the extensive
software packages.
