Important. This ATEX Category depends on the application
(see below) and also on the intrinsic safety level of the
field indicator supply (associated apparatus) which can
sometimes suitably be [ib] instead of [ia]. As it is well known,
the level of an intrinsic safety system is determined by the
lowest level of the various apparatus used, i.e., in the case of
[ib] supply, the system takes over this level of protection.
The meaning of ATEX code is as follows:
— II: Group for surface areas (not mines)
— 1: Category - It means that only a part of the transmitter
complies with category 1 (see next application sketch).
— G: Gas (dangerous media)
— D: Dust (dangerous media)
— Tx°C: Maximum surface temperature of the transmitter
enclosure with a Ta from -50°C to +40°C for Dust (not
Gas) with a dust layer up to 50 mm depth. T85°C: as
before for Dust for a Ta +85°C.

The other marking refers to the protection type used according
to relevant EN standards:
— Ex ia: Intrinsic safety, protection level "a"
— IIC: Gas group
— T4: Temperature class of the field indicator
(corresponding to 135°C max) with a Ta from -50°C to +85°C
— T5: Temperature class of the field indicator
(corresponding to 100°C max) with a Ta from -50°C to +40°C
— T6: Temperature class of the field indicator
(corresponding to 85°C max) with a Ta from -50°C to +40°C
About the applications, this field indicator can be used in Zone
"0" (Gas) classified areas (continuous hazard).
About Dust application, the field indicator is suitable for "Zone
21" according to the EN 60079-0 and EN 60079-11 as it is
shown on the relevant part of the sketches.

Note: the protection is mainly assured by the "IP" degree
associated to the low power from supply. This can either be [ia]
or [ib]
