Safety instructions for use in explosion hazard areas Zone 2
Conformity with DIN EN 60079-15 "Explosive atmospheres - Part 15: Equipment protection by type of
protection "n" : 2011-02 and 2020-03" was proven with report no. 2.12BR190104AUG2V06 "Bericht
zur Eignung des Standardgehäuses der Messgeräte FTC3xx und FTC4xx für Zone 2, Schutzart „nR“,
schwadensicheres Betriebsmittel"
. If flammable gas is fed into the analyzer at overpressure, a leak in
the gas path could result in an ignitable mixture in the analyzer housing. To prevent the formation of an
explosive atmosphere in the device itself even in the event of a leakage, the housing is internally filled
with glass beads which, due to their filling density, leave only a small free volume of about 0.15l in the
housing. Moreover, due to the small size of the glass beads, this free volume is fragmented into such
small sub-volumes that a flame cannot spread.
Therefore the device may only be opened by the
manufacturer.
1.5
Intended Use
Only gases that are non-corrosive and free of condensate, dust, aerosol or oil mist may be lead in the
FTC-series gas analyzer. Flammable gases require appropriate protective measures. Explosive gases
may not be lead into the FTC. The Instrument may not be used in hazardous areas. Please contact
[email protected] for detailed information and solutions.
