2-16 5000 Multi Point Moisture Analyzer

• Conditioned Sample Gas Used As Reference

Configure sample system as shown in Figure 9a. Standard and optional conditioning compo

nents (dryers, contaminant traps) should be strapped in the upright position to support

beams. Note that the dryer(s) must be vertical to avoid channeling (voids in the sieve).

• Separate Gas Source Used As Reference

Configure sample system as shown in Figure 9b. Standard and optional conditioning compo

nents (dryers, contaminant traps) should be strapped in the upright position to support

beams. Note that the dryer(s) must be vertical to avoid channeling (voids in the sieve).

A separate source (if present) should also be run through an oil/air separator to remove trace quan-

tities of oil from the gas. Oil in the reference stream will cause rapid contamination of the analyzer

cell.

Gas Connections to Analyzer

Proper sample line purge must be performed before connecting sample line to analyzer. Condensate

in the sample line can migrate to the cell which may result in irreparable damage to the crystal

oscillator.

1. Open the main sample line shutoff valve and pressure reducer at sample tap 1 carefully;

vent the line to appropriate area and purge it with clean, dry instrument air or nitrogen until

it appears dry.

2. Close the main sample line shutoff valve and pressure reducer and connect the sample line

to the appropriate sample switching valve. Refer to Figure 9c (page 2-13) for recommended

sample switch ing configuration.

3. Repeat steps 1 and 2 for all other sample taps.

4. Connect sample switching output line to field unit

inch sample inlet fitting (tee fitting if

sample is to be used as reference).

5. Connect the reference gas line (from either the sample or a separate source) to the dryer and

optional sample conditioning components (ultra-dryer and trap) as shown in Figures 9a and

9b.

6 Connect the output of the last conditioning component to the field unit

inch reference

inlet fitting.

7. Connect vent line to analyzer

inch exhaust port fitting. Vent the line to appropriate area.

Consult plant safety personnel for appropriate venting guidelines.
