Siemens ULTRAMAT 6 Series - Gas Connections

4.3 Gas connections
4.3.1 Gas preparation
To prevent contamination of parts through which the sample gas 󹪞ows, the sample gas must be
prepared appropriate to the measurement. We recommend the following minimum
con󹪝guration:
• Gas sampling unit with 󹪝lter
• Analyzer 󹪝lter (approx. 1-2 μm)
Depending on the characteristics of the sample gas it may be necessary to provide additional
equipment such as an external gas suction pump, sample gas cooler, wash bottle or pressure
reducer.
4.3.2 FIDAMAT 6 gas connection
The FIDAMAT 6 analyzer needs combustion air and combustion gas (hydrogen) as additional
supply gases for operation.
4.3.3 Toxic and corrosive gases
Appropriate components must be used for toxic and/or 󹪞ammable gases. These components
must be approved for the respective application.
We recommend that you consult our technical department before connecting toxic or
corrosive gases.
Please note in particular that the control cabinet housing the analyzer must have a protection
rating of at least IP54 and be purged with a suitable purging gas.
WARNING
Toxic and/or corrosive gases
When measuring toxic or corrosive gases, it could occur that sample gas accumulates in the
analyzer because of leaks in the gas path.
To prevent the danger of poisoning or damage to parts of the analyzer, the analyzer must be
purged. The gas displaced by purging must be collected using appropriate equipment and
disposed of environmentally-friendly via an exhaust line.
