1/2 :

Category - It means that only a part of the transmitter complies with category 1 and a
second part complies with category 2 (see next application sketch)

G :

Gas (dangerous media)

D :

Dust (dangerous media)

T80

Note: the number close to the CE marking of the transmitter safety label identifies the Notified Body which carries
out the Surveillance for the production of the transmitter.

The other marking refers to the protection type used according to relevant EN Standards:

EEx d: Flameproof
IIC :

Gas group

T6 :

About the applications, this transmitter can be used in Zone “0” (Gas) classified areas (continuous hazard) with its “process
part” only, whereas the remaining part of the transmitter, i.e. its enclosure, can be used in Zone 1 (Gas), only (see sketch
below). Reason of this is the process part of the transmitter (normally called primary transducer) that provides inside separation
elements to seal off the electrical sensor from the continuously hazardous process, according to the EN50284 and EN50018.
About Dust application, the transmitter is suitable for "Zone 21" according to the EN 50281 as it is shown on the relevant part of
the sketch:

IP code
About the degree of protection provided by the enclosure of the pressure transmitter, the 600T EN SERIES has been certified IP67
according to EN 60529 standard (this is equivalent to IEC 529).
The first characteristic numeral indicates the protection of the inside electronics against ingress of solid forein objects including
dusts. The assigned “6” means an enclosure dust-tight (no ingress of dust).
The second characteristic numeral indicates the protection of the inside electronics against ingress of water. The assigned “7”
means an enclosure water-protected against a temporary immersion in water under standardized conditions of pressure and time.
