ADDENDUM FOR "EX SAFETY" ASPECTS AND "IP" PROTECTION (EUROPE)
According to ATEX Directive (European Directive 94/9/EC of 23 March 1994) and relative European Standards which can
assure compliance with Essential Safety Requirements, i.e., EN 60079-0 (General requirements), EN 60079-1 (Flameproof
enclosures "d"), EN 60079-11 (Intrinsic safety "i"), EN 60079-26 (Equipments, group II, category 1G) for GAS and
EN 61241-0 (General requirements), EN 61241-1 (Flameproof enclosures "d"), EN 61241-11 (Intrinsic safety "i") for DUST.
The pressure transmitters of the 2600T SERIES have been certified for the following group, categories, media of dangerous
atmosphere, temperature classes, types of protection. Examples of application are also shown below by simple sketches.
Certificate ATEX II 1G Ex ia IIC T6
ZELM Certificate number ZELM 08 ATEX 0361 X
The meaning of ATEX code is as follows:
II :
Group for surface areas (not mines)
1 :
Category
G :
Gas (dangerous media)
(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:
Ex ia : Intrinsic safety, protection level "a"
IIC : Gas group
T6 : Temperature class of the transmitter (which corresponds to 85°C max)
with a Ta (ambient temperature) +40°C
About the applications, this transmitter can be used in "Zone 0" (Gas) as it is shown on
the picture.
Certificate ATEX II 1/2G Ex ia IIC T6
ZELM Certificate number ZELM 08 ATEX 0361 X
The meaning of ATEX code is as follows:
II :
Group for surface areas (not mines)
1/2 :
Category
G :
Gas (dangerous media)
(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:
Ex ia : Intrinsic safety, protection level "a"
IIC : Gas group
T6 : Temperature class of the transmitter (which corresponds to 85°C max)
with a Ta (ambient temperature) +40°C
About the applications, this transmitter can be used in "Zone 0" (Gas) and "Zone 1" as
it is shown on the picture.
