2.11 PED (Pressure Equipment
Directive)
(1) General
• EJA series of pressure transmitters are categorized
as pressure accessories under the vessel section of
this directive 97/23/EC, which corresponds to
Article 3, Paragraph 3 of PED, denoted as Sound
Engineering Practice (SEP).
• EJA130A, EJA440A, EJA510A, and EJA530A can
be used above 200 bar and therefore considered as
a part of a pressure retaining vessel where category
lll, Module H applies. These models with option
code /PE3 conform to that category.
(2) Technical Data
• Models without /PE3
Article 3, Paragraph 3 of PED, denoted as Sound
Engineering Practice (SEP) .
• Models with /PE3
Module: H
Type of Equipment: Pressure Accessory - Vessel
Type of Fluid: Liquid and Gas

(3) Operation
CAUTION
• The temperature and pressure of fluid should
be applied under the normal operating condi-
tion.
• The ambient temperature should be applied
under the normal operating condition.
• Please pay attention to prevent the excessive
pressure like water hammer, etc. When water
hammer is to be occurred, please take mea-
sures to prevent the pressure from exceeding
PS by setting the safety valve, etc. at the
system and the like.
• When external fire is to be occurred, please
take safety measures at the device or system
not to influence the transmitters.
