All of the SGA components are mounted onto an assembly plate. This plate is designed be
mounted vertically, on a wall say, or in a specially designed cabinet.
Four M8 threaded bolts (not included with delivery) are required to attach the assembly
board to the wall or other vertical surface. Further specifications can be found in Appendix F.
Connecting sleeves (Swagelok/ DK-Lok) with an outer diameter of 6 mm are used to connect
the SGA 003 to the gas line.
Refer to the manometer or the pressure transmitter to read the pressure conditions at the
control outlet.
If desired, the SGA can also be outfitted with a module to carry out reference measurements,
or “reference module”.
All of the necessary quick-connection couplers required for connecting the reference module
to the SGA 003 are included in delivery.
3.3 dpW and dpHC module
!
The function of this module is to ensure that gas reaches the measurement chamber of the
analyzer in the SGA system under operating pressure. At the same time, the module
guarantees that gas is delivered to the installed reference instrument at operating pressure
(or other pressure conditions as desired).
For a description of the dpW and dpHC module see Appendix F, which also includes an
installation schematic.
The dpW and dpHC module ensures that the sample gas is examined at operating pressure,
independent of the process-switch settings (see Appendix C).
By turning the process switch, which is located at the control output, is possible to test the
dew point at:
operating pressure (position “W”)
reduced pressure (position “HC”).
The manometer (6) and the pressure transmitter (28) display the current operating pressure.
