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 50014 (General requirements) EN 50018 (Flameproof enclosures
"d") EN 50020 (Intrinsic safety "i") EN 50284 (Equipments, group II, category 1G), the pressure transmitters of the 600T EN
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.
a) Certificate ATEX II 1G, EEx ia IIC T5 (-40°C ≤ Ta ≤+40°C)
TUV Certificate number Ex 50012 42206 001.
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:
EEx ia :
Intrinsic safety, protection level "a"
IIC :
Gas group
T5 :
Temperature class of the transmitter (which corresponds to 100°C max)
with a Ta (ambient temperature) +40°C
T4 :
Temperature class of the transmitter (which corresponds to 135°C max)
with a Ta (ambient temperature) +85°C
About the applications, this transmitter can be used in "Zone 0" (Gas) classified area (continuous hazard) as it is shown on the
following sketch:
EEx ia IIC T4 (-40°C ≤ Ta ≤+85°C)
