2.6 Pressure Equipment
Directive (PED)
(1) General
• EJX/EJA-E Series pressure transmitters are
categorized as piping under the pressure accessories
section of directive 97/23/EC, which corresponds to
Article 3, Paragraph 3 of PED, denoted as Sound
Engineering Practice (SEP).
• EJX110A-MS, EJX110A-HS,
EJX110A-VS, EJA110E with /HG, EJ130,
EJ440, EJ510-D, EJ530-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.
(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
Group of fluid: 1 and 2

*1: PS is maximum pressure for vessel itself based on
Pressure Equipment Directive 97/23/EC. Refer to
General Specification for maximum working pressure of a
transmitter.
*2: Referred to Table 1 covered by ANNEX II of EC Directive
on Pressure Equipment Directive 97/23/EC
(3) Operation
CAUTION
• The temperature and pressure of fluid should
be maintained at levels that are consistent with
normal operating conditions.
• The ambient temperature should be maintained
at a level that is consistent with normal operating
conditions.
• Please take care to prevent water hammer and the
like from inducing excessive pressures in pipes
and valves. If phenomena are likely, install a safety
valve or take some other appropriate measure to
prevent pressure from exceeding PS.
• Take appropriate measures at the device or
system level to protect transmitters if they are to be
operated near an external heat source.
