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 installed, the clamping screws take on the role of length
compensation for the gas connections.
