Parameter	Description
Pressure Equipment Directive	The ST 3000 pressure transmitters listed in this Specification have no pressurized
(97/23/EC)	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).

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.
