S Gas Analyzer BA02191C
3-16 Endress+Hauser
Using 1/4 in. O.D x 0.035 in. wall thickness, seamless stainless steel tubing is
recommended. Refer to the system layout drawing in Appendix A for supply
and return port locations.
Instrument air
Specific ventilation may be required depending on application and analyzer
configuration. For example, if air-operated valves are used in the analyzer, they
should be supplied with instrument air or nitrogen filtered with a 5 micron
particulate filter. If there is lubrication oil, aerosols or other liquids in the air,
these must be removed using an appropriate coalescing filter. Pressure should
be set within the range indicated on the analyzer tag at the instrument air inlet.
Refer to the specifications and system drawings in Appendix A. If no setting is
listed, pressure should be maintained between 65 PSIG and 150 PSIG.
There are no special requirements for ventilation of the analyzer.
Refer to Appendix B for more information related to maintenance or
troubleshooting.
To connect the sample supply line
1. First confirm that the sample probe is correctly installed at the
process supply tap and that the sample probe isolation valve is
closed.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before installing
the SCS.
Consult sample probe manufacturer instructions for proper
installation procedures.
The process sample at the sample tap may be at a high pressure.
Use extreme caution when operating the sample probe isolation
valve and field sample reducing pressure regulator.
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
