for special versions, e.g. high pressure tubes, non-standard flanges, other
types of protection for the primary head are required:
DN25-150
EEx q (Powder filling) and EEx e (Increased safety)
DN200-300
EEx e (Increased safety)
•
internal electrode circuit :
always
EEx ia (Intrinsic Safety)
The resulting marking (EEx code) on the data sticker is therefore:
DN size
EEx e or EEx ia connection
compartment
EEx d connection compartment

A representative example of the data sticker is shown in figure 1. Order specific
deviations, e.g. in the code letters for used types of protection, are possible.
