Gas sampling and gas conditioning technology 2-1.1.7.2-ME
14.1 CONNECTION OF THE SUPPLY AND SAMPLE LINES
All pneumatic lines have to be inserted through the CES cable entry, size 5, with an operative range of
36
– 70mm. It is located in the bottom of the FRP-housing. After insertion and connection of all lines
the CES cable entry can be shrinked by an air heater.
N O T E !
Increases of pressure due to use of long sample gas lines at the outlet may have a
great influence on the measuring result. For this reason, we recommend the fol-
lowing nominal widths and lengths for the sample lines in dependence on the type
of injector:
Injector type I:

i
1/4” max. 50m

i
3/8” max. 150m
Injector type II:

i
8mm max. 15m

i
10mm max. 40m

i
12mm max. 80m
The connections for the supply and sample lines are as follows:
Connection Dimension
Testgas In Tube 1/4”
Dilution gas In Tube 1/4”
Low pressure manometer Tub e 1/4”
Sample gas Out (diluted) Tube 3/8”
Bypass gas In Tube 1/4”
Bypass gas Out (diluted) Tube 1/4”
Sample gas Out (undiluted) Tube 1/4”
Blow back In Tube 3/8”
