Product Description

2.3 Function of the pressurized enclosure system

Purpose
The pressurized enclosure prevents an explosive atmosphere being created inside the enclosure. To this purpose, the gas analyzer enclosure is filled with a protective gas. Apart from that, it also ensures the gas pressure inside the gas analyzer enclosure is higher than the ambient air pressure.
Safety functions
● The enclosure is pre-purged automatically before start-up. The mains supply for the gas analyzer is first switched on afterwards.
● The mains supply of the gas analyzer is switched off automatically should the pressur­ized enclosure not be in the correct operating state (malfunction).
Functionality during operation
The pressurized enclosure system functions in “leakage compensation” operating mode: A certain protective gas pressure is created in the gas analyzer enclosure after pre-purging has completed. If the protective gas pressure drops below the minimum pressure set, pro­tective gas feed is activated until the rated pressure is reached again.
On the Enclosure GMS815P-PS-2G, a certain amount of protective gas leaks out of the gas analyzer enclosure through the protective gas outlet. This means the protective gas feed is activated often to restore the pressure. This creates a more or less permanent protective gas flow with the required flowrate.
