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).

 

 

*See Figure 13 for Fill Fluid temperature limits.

**2-inch Sanitary Seals are limited to 15 ft. (4.6 m) capillary length.

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.
