4.2 Operation with at least one OXYMAT 7

4.2 Operation with at least one OXYMAT 7
Overview
If the sample gas is pumped into the analyzer module, surges may occur through operation
which can result in an unstable display of measured values. Fitting a sample gas restrictor in
the sample gas inlet of an OXYMAT 7 remedies this situation.
A further measure is the connection of a "pneumatic low pass" consisting of a restrictor and
a damping vessel.

When using two analyzer modules:
● Two analyzer modules in series:
● Two analyzer modules in parallel: Sample gas restrictor before each sample gas
