1: Ideal measuring point

5 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 measurement 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 scavenging air. Ap-
prox. 50 l/min with a maximum pressure of 6 bars are required for that. Use oil-free and dirt-free
compressed air. If the expected ambient temperatures are > 65 °C, a cooling system is required.
6 Assembly fibre optic cable
One end of the optical fibre has a nameplate showing the serial number of the corresponding
basic pyrometer. This is the end which must be screwed onto the pyrometer. For proper connec-
tion, the arrow on the nameplate of the fibre optic cable and the arrow on the pyrometer should
point toward each other. The serial number of the measuring head should also correspond to
the pyrometer.
ATTENTION
The fibre optic cable must not be exposed to tensile load and must not be
twisted. The minimum bending radius is 125 mm.
