Metrohm NIRS XDS Process Analyzer – SingleFiber - Manual (Page 78)

76 ▪▪▪▪▪▪▪
Fiber Optic Cables connect at the top of the
enclosure as shown. This instrument has only one
channel, mounted at the rear-most entrance.
Stainless-steel plugs seal the unused entrances.
Up to nine channels may be used, when the
multiplexer is installed.
When optional temperature probes are used, the
number of fiber optic channels may be reduced, as
the temperature probes exit using these openings.
A fiber optic modem is available for the XDS
Process Analytics Instrument. This modem mounts
low in the cabinet, and accepts a 100Base-T pair
of fiber optic communication fibers.
The optional temperature probes (shown below
right) require an interface board inside the XDS
Process Analytics Instrument cabinet.
This shows the interface board, which is located at
the upper right side of the cabinet, mounted on
the back wall.
The temperature probes are shown. These may be
mounted in the process stream.
The temperature input will be passed to the
Analyzer as part of the spectral signal.
