GAS 222.35 AMEX
1 Introduction
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 addition to the job number/ID number, this also contains the article
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 re-
commend 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 compres-
sion (high blowback pressure against contaminated filter). The operator is responsible for compliance with these conditions tak-
ing into account his risk assessment.
