3-2 | 3050-TE Moisture Analyzer
Sample pressure and temperature requirements
Pressure reduction is user supplied to ensure sample pressure to the analyzer
remains within the range of 20 - 50 psig. The pressure reducer/regulator with
gauge should be installed near the sample tap in-between the tap and analyzer. For
optimum performance, sample line should be heat traced to maintain a constant
sample temperature. Optimum sample gas input temperature is 60
°
C.
Mechanical Installation
Locate the 3050 system as close as possible to the sample source. The unit should
be protected from direct exposure to weather and sunlight; and located so that
the ambient temperature specifications will not be exceeded.
1. If not already installed, install a main process shut-off valve and pressure
reducer (recommended) at the sample tap. Refer to figure 3.4.
2. Mount system in selected location and bolt in place. Refer to figure 3.3.
3. Connect instrument air to 1/4-inch compression fitting. Maximum input 150
psig.
a. Set cabinet cooler to 70-100 psig.
b. Set pilot valve to 70-100 pisg.
4. Connect the exhaust fitting to appropriate vent system.
5. Open the main process shut-off valve and purge sample line to an appropriate
area for at least five minutes. Close the main process shut-off valve. This will
help prevent contamination from entering the cell.
6. Connect the sample line to the sample inlet 1/8-inch compression fitting.
7. Re-inspect process line connections making certain that all are connected to
the proper external supply, exhaust, and drain tubing such that there shall be
no release of hazardous process gas to the atmosphere.
a. Set back pressure regulator (if installed) to 0-15 psig.
8. Open valve to dryer prior to closing the lid.
9. Open sample valve.
