Oxygen Monitor SGM7.2.4/7.2.6 2 Application field
8
2 Application field
The protective gas monitor SGM7.2.4 serves the continuous measuring of
the oxygen concentration in industrial, laboratory and protective gases as
well as in the process of mixing and producing of special forming gases in
industry. The measuring of the free oxygen concentration in inert gases and
also the measuring of bound oxygen in gas compounds is possible.
Designate
use
The main application fields of the oxygen monitor are:
• processes for mixing and producing of forming gases
• production processes of welding and soldering, especially gas-
shielded arc welding in steel and container production as well as plant
construction
• production processes of electronic components under buffer gas.
The introduction of explosive gas compounds, high concentrations of
halogens or sulphuric gases (e.g. SO
2
) into the SGM7.2.4 is not permitted.
The contact of the SGM7.2.4 with siliconic or phosphoric compounds is not
permitted either.
The SGM7.2.4
Functions
• measures and indicates the oxygen concentration in a measuring gas
continuously;
• indicates any deviations of the oxygen concentration in the measuring
gas from an adjustable set value;
• monitors the course of a particular production process under buffer
gas;
• checks the purity of buffer gases and determines whether the
requested protective effect of the buffer gas is reached.
The requirements and limit values provided in "Technical data" must be
strictly observed.
Any other use is treated as non-authorized use.
