6.4 Shadow Monitoring (A-CS-SM-KIT-485)
The linescanners can be hindered from monitoring the complete kiln by physical obstructions and by shadows from
the tires. With the shadow monitoring kit additional pyrometers can be installed and configured to monitor these
"shadowed" portions. The temperature values from these pyrometers are integrated in the scanned data from the
linescanners and the results are displayed as one homogenous thermogram.
For an overview of a system configured with Shadow Monitoring, see section 8.2
Accessories, page 48.
