Figure 4-2
For rack-mounted and wall-mounted devices, the sample gas connections of the analyzer
modules are 6 mm nozzles. Depending on the analyzer module, either clamping screws or
sample gas restrictors are mounted onto these nozzles that are then connected tightly to the
incoming gas lines and outgoing gas lines. Sample gas restrictors as well as clamping
screws ensure a gas-tight connection between the gas connection and the gas line.
Depending on the application, however, you may also need to remove the sample gas
restrictor or move it to another module. The sample gas restrictor is screwed (grub screw)
onto the bushing of the gas path.
If no sample gas restrictors are screwed in, the clamping screws take on the role of length
compensation for the gas connections.
