EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A 15
Case purging
In order to protect the electronic assemblies from an ingressing aggressive
atmosphere or corrosive sample gas components, the flameproof case can
be purged with air or nitrogen.
The purge gas is fed in and conducted away via two flame barriers, which are
open on the inside of the flameproof case.
Remark: The case purging has no meaning in the sense of a pressurized en-
closure to IEC/EN 60079-2.
Explosion protection
The gas analyzers are designed for use in hazardous areas. They are certified
in accordance with the European Directive 2014/34/EU ("ATEX Directive")
and the pertinent IEC standards.
The housings are designed as field housings in the type of protection
"Flameproof Enclosure 'd'". They comply with the requirements of the explo-
sion group IIC. As a result, the gas analyzers can also be used in atmos-
pheres containing hydrogen or acetylene.
