6 Installation
6.1 Selecting an installation location
When choosing the installation location and during the pyrometer alignment, it is
imperative to ensure that only the free pouring stream is within the field of view�
When the background is hotter than the object focused on or when the meas-
urement is made through the inoculant, the accuracy of measurement will be
influenced�
The pyrometer should be oriented as far as possible at right angles to the pouring
stream� Ideally, the pyrometer should be mounted so that it is aligned with the back
of the pouring stream�
1: Ideal measuring point
6.2 Mechanical installation
The distance should be adjusted in that way, that the pouring stream is wide
enough to fill up at least 30 % of the measurement area� Reduce the distance, if
the pouring stream covers less than 30 % of the measurement area� When aiming
the pyrometer, make sure that the pouring stream is in the centre of the measure-
ment area� During pouring it must be ensured that the pouring stream is always
within the measuring field, even if the pouring stream is fluctuating�
In order to prevent the pyrometer optics from contamination, connect the scaveng-
ing air� Approx� 50 l/min with a maximum pressure of 6 bars are required for that�
Use oil-free and dirt-free compressed air�
