Mechanical Installation

If the sample contains
particulates greater than 15
microns, install a filter on the
sample gas inlet.

Locate the CG1000-RTP as close to sampling system as possible.
The accuracy of the oxygen readings are pressure- and flow-dependent.

Maintain the same flow rate and inlet pressure during both calibration
and normal operations. Keep the flow rate between 125 to 175 cc/min
to maintain accurate readings. To detect when the flow exceeds these
limits, Alarm 3 can be programmed to alarm on both the high and low
flow rate.
Figure 3-1 shows the sample inlet and outlet ports on the CG1000-RTP .
The sample gas should be clean and dry. If the sample contains any con-
densing moisture, the entire sample line should be heat-traced.
Be aware that combustibles in the sample can burn with available

oxygen to provide lower-than-expected oxygen levels, especially if
measuring oxygen in the low PPM ranges.
NOTE
Keep the inlet pressure as low as possible to prevent damage to the cell or
cell O-ring seal. The sample gas inlet pressure into the CG1000-RTP must
be less than 3 PSIG.
