Hardware Installation and Maintenance Manual 4–1
4 - SAMPLE CONDITIONING SYSTEM
(SCS)
SS500 and SS2000 systems may be ordered with an optional integrated sample
conditioning system (SCS). Each SCS has been specifically designed to deliver
a sample stream to the analyzer that is representative of the process stream
at the time of sampling. To ensure the integrity of the sample stream and its
analysis, care must be taken to install and operate the SCS properly. Therefore,
any personnel intending to operate or service the analyzer and SCS should
have a thorough understanding of the process application and the design of the
analyzer and SCS.
Most problems experienced with sample systems tend to result from operating
the system differently than intended. In some cases, the actual process
conditions may be different than originally specified (e.g., flow rates, presence
of contaminants, particulates, or condensables that may only exist under upset
conditions). By establishing understanding of the application and the design of
the system, most issues can be avoided altogether or easily diagnosed and
corrected ensuring successful normal operation.
If there are any remaining questions concerning the design, operation, or
maintenance of the SCS, contact your factory service representative.
Personnel should have a thorough understanding of the operation
of the SS500/SS2000 analyzer and the procedures presented
here before operating the sample conditioning system.
The process sample at the sample tap may be at a high pressure.
A field pressure reducing regulator is located at the sample tap to
reduce the sample pressure and enable operation of the sample
conditioning system at a low pressure. Use extreme caution when
operating the sample probe isolation valve and field pressure
reducing regulator.
The process sample at the sample tap may be at a high pressure.
Make sure that the field pressure reducing regulator is equipped
with an appropriate pressure relief valve.
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 operating
the SCS.
