Pressure Equipment Directive
(97/23/EC)
NOTE: Pressure transmitters that are part of safety equipment for the protection of piping (systems) or vessel(s) from
exceeding allowable pressure limits, (equipment with safety functions in accordance with Pressure Equipment Directive
97/23/EC article 1, 2.1.3), require separate examination.

The ST 3000 pressure transmitters listed in this Specification have no pressurized
internal volume or have a pressurized internal volume rated less than 1,000 bar (14,500
psig) and/or have a maximum volume of less than 0.1 liter. Therefore, these
transmitters are either; not subject to the essential requirements of the directive
97/23/EC (PED, Annex 1) and shall not have the CE mark, or the manufacturer has the
free choice of a module when the CE mark is required for pressures > 200 bar (2,900
psig).
