2.11 Pressure Equipment
Directive (PED)
(1) General
• EJX/EJA-E Series pressure transmitters are
categorized as piping under the pressure
accessories section of directive 2014/68/EU,
which corresponds to Article 4, Paragraph 3 of
PED, denoted as Sound Engineering Practice
(SEP).
• EJ510-D, EJ530-D, EJX610A-D,
and EJX630A-D can be used above 200
bar and therefore considered as a part of a
pressure retaining vessel where category III,
Module H applies. These models with option
code /PE3 conform to that category.
