The SCS enclosure contains the measurement cell and heater along with flow
devices to control flow and pressure for the measurement cell and the bypass
loop.
Power is connected to each electronics enclosure of the analyzer from a 120
VAC, 240 VAC or 18 to 24 VDC power source, as shown on Figure 1–5 on page
1–10. Sample supply/return and instrument air are connected on the sides of
the SCS enclosure.
