The meaning of ATEX code is as follows:
II :
Group for surface areas (not mines)
2 :
Category
G :
Gas (dangerous media)
D :
Dust (dangerous media)
Ex d:
Explosionproof
IIC :
Gas group
T6 :
Temperature class of the indicator (which corresponds to 85°C max) with a Ta (ambient temperature) +70°C
T5 :
Temperature class of the indicator (which corresponds to 100°C max) with a Ta (ambient temperature) +85°C
T80°C: Maximum surface temperature of the indicator enclosure with a Ta (ambient temperature) +70°C
for Dust (not Gas) with a dust layer up to 5 mm. For application with dust layer between 5 and 50 mm,
max
surface temperature must be consider according to IEC 61241-14 chapter 6.3.3.3
T95°C: As before for Dust for a Ta +85°C
Note: the number close to the CE marking of the indicator safety label identifies the Notified Body which carries
out the Surveillance for the production of the indicator.
The other marking refers to the protection type used according to relevant EN Standards:
About the applications, this indicator can be used in "Zone 1" (Gas) and "Zone 21" (Dust) classified areas (occasional
hazard) as it is shown in the following sketch:
Application with Gas
Zone "1"
mod. 695FI
category 2G
(Ex d)
IP code
About the degree of protection provided by the enclosure of the field indicator, the 600T EN SERIES has been certified
IP67 according to EN 60529 standard (this is equivalent to IEC 60529).
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 assig-
ned "7" means an enclosure water-protected against a temporary immersion in water under standardized conditions of
pressure and time.
