Internal power supply
The instrument is designed to feed 3 optics housings using a cable that is not longer than 500m.
3.5 Flange installation requirements
Before the gas analyzer and its optics housings can be used, a pair of process flanges should be
installed at the measurement site. The flanges must be installed at a safe and accessible position
to make installation and service easy to accomplish.
The flanges should be welded to the wall of the furnace or funnel as shown in the figure below.
The flange must protrude at least 100 mm (4") from the wall and 0-30 mm (0-1.2") into the
furnace/funnel.
