to the oxygen sensor. Depending on the application and/or ambient conditions,
the SCS may also contain a heater and thermostat to maintain the interior of
an optional enclosure at a constant temperature. Refer to the Sample
Conditioning System (SCS) Operating Instruction for more information.
Oxygen probe
The oxygen sensor consists of a polymer optical fiber (POF) with a polished
distal tip that is coated with a planar oxygen-sensitive foil. The end of the
polymer optical fiber is covered with a high-grade steel tube to protect both the
sensor material and the POF. Refer to Figure 1–3. Typically, the fiber is coated
with an optical isolated sensor material in order to exclude ambient light from
the fiber sensor spot.
