manufacturer reserves the right to change performance-, spe-
cification- or technical data without prior notice. Please keep
these instructions for future reference.
1.1 Intended Use
The sample gas probe is intended for installation into gas
analysis systems in commercial applications.
Sample gas probes are among the main components in a gas
conditioning system.
• Therefore also note the related drawing in the data sheet
in the appendix.
• Before installing the device, verify the listed technical
data meet the application parameters.
• Further verify all contents are complete.
Please refer to the type plate to identify your model. In addi-
tion to the job number/ID number, this also contains the art-
icle number and model designation.
Please note the specific values of the device when connecting,
and the correct versions when ordering spare parts.
Passing through gases
Flammable gases above the UEL may only be blown back with
inert gases. Flammable gases from 25 % LEL and up to the UEG
may be blown back provided the operator ensures the blown
back gas is not and cannot be explosive. For safety reasons we
recommend only using inert gases in these cases as well.
Blowing back explosive atmospheres (range from UEG to OEG)
with the probes is prohibited due to possible adiabatic com-
pression (high blowback pressure against contaminated fil-
ter). The operator is responsible for compliance with these
conditions taking into account his risk assessment.

2 Safety Notes
The maximum surface temperature of the probes solely varies
by operating conditions (steam temperature, sample gas inlet
temperature, ambient temperature, fluid flow rate). For use
in explosive areas please particularly note the related hazard
warnings.
The equipment must be installed by a professional familiar
with the safety requirements and risks.
Be sure to observe the safety regulations and generally applic-
able rules of technology relevant for the installation site. Pre-
vent malfunctions and avoid personal injuries and property
damage.
The operator of the system must ensure:
• Safety notices and operating instructions are available
and observed,
• The respective national accident prevention regulations
are observed,
• The permissible data and operational conditions are
maintained,
• Safety guards are used and mandatory maintenance is
performed,
• Legal regulations are observed during disposal,
• compliance with national installation regulations.
