group ll, category 1/2G and according to RL
99/92/EG (ATEX 137) may be used in zones 0/1
or 0/2 and gas groups llA, llB and llC that are
potentially explosive due to flammable substances in
the temperatures classes T3 to T6.
For use/installation, the requirements of EN 60079-

rature measuring circuit are part of a common intrin-
sically safe system and are for operation connected
to a separately certified transmitter.
