The meaning of ATEX code is as follows:
II : Group for surface areas (not mines)
1 : Category
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 on application sketch)
G : Gas (dangerous media)
D : Dust (dangerous media)
T50°C: Maximum surface temperature of the transmitter enclosure with a Ta (ambient temperature)
+40°C for Dust (not Gas) with a dust layer up to 50 mm depth.
T95°C: As before for Dust for a Ta +85°C and for Flameproof protecion type:
T85°C: Maximum surface temperature of the transmitter enclosure with a Ta (ambient temperature)
+75°C for Dust (not Gas) with a dust layer up to 50 mm depth.
(Note: the number close to the CE marking of the transmitter safety label identifies the Notified Body which
has responsibility for the surveillance of the production)
The other marking refers to the Intrinsic safety 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
T4 : Temperature class of the transmitter (which corresponds to 135°C max) with a Ta (ambient
temperature) +85°C
The other marking refers to the Flameproof protection type used according to relevant EN standards:
Ex d: Flameproof
IIC : Gas group
T6 : Temperature class of the transmitter (which corresponds to 85°C max) with a Ta (ambient
temperature) +75°C.
About the applications of the transmitter see the relevant sketch.
