3.1.3 KRAY 2.848.015-01 version with SGA 003
gas preparation system
(Appendix E)
The CP 2M dew point analyzer can be delivered with the SGA 003 gas preparation system
already installed.
This system is suitable for heated indoor spaces and block boxes.
Areas of application for which the SGA 003 is appropriate include the transportation, storage,
and processing of various gases.
3.2 Description and construction of the
CP 2M with the SGA 003 gas preparation
system
The SGA 003 gas preparation system ensures that the sample gas is free of various
mechanical and aerosol contaminants.
The revolutionary principle behind our patented gravity filter (Appendix E, position 2) is one
of the core elements of the SGA 003. This type of filtration eliminates the need for any kind of
filter membrane or cartridge, which, due to the unpredictable consequences of wear, are the
weak points of other gas preparation systems.
In contrast to traditional filter systems, gravity filtration avoids causing changes to gas
sample conditions due to a compromised or clogged filter element. In other words, our SGA
system permanently provides the highest standard of sample gas preparation.
The SGA’s design makes it possible to establish the dew point of water (dpW) at operating
pressure, and the dew point of hydrocarbons (dpHC) at reduced pressures — for example,
27 bar.
The SGA 003 gas preparation is the first universal solution for all of the typical gas sector
problems associated with dew point measurement.
This system is able to take measurements at various working pressures, at contractually
defined pressures, and at any other pressures as desired, up to 160 bar.
The SGA 003’s innovative reference module is another special feature of this gas
preparation system. This system makes it possible to quickly mount a “Hygrovision” series
analyzer as a control instrument. With the control instrument in place, the operator can obtain
information about all of the processes in the sample gas with absolute certainty, and he or
she can quickly and inexpensively check the validity of the present measurement results at
any time, or when documentation requires.
In order to simplify attachment of the “Hygrovision” reference instrument, the SGA has a
foldout mounting arm as well as the necessary gas delivery lines. The SGA unit also has an
additional power connection for the reference analyzer (Appendix E, position 16). Data
transfer via a 4 – 20 mA interface is also supported by this connection.
