Pressure Equipment Directive 97/23/EG (PED)

1. Devices without pressure chamber
   - pressure intermediaries and/or pressure transmitters with pressure intermediary, e.g. DMP 331 P
   - screwed probes and/or pressure transmitters with front-flush fitting pressure sensor,
   e.g.. LMP 331, LMK 331, LMK 351
   - dipping probes, e.g.. LMP/LMK 307, LMK 382, LMK 858
   These devices do not fall under the Pressure Equipment Directive, since they have no and/or only a safetyrelevant negligibly small pressure chamber.
   According to the Article 1 paragraph 2 number 2.1.4 PED; pressure equipment must have "a pressurebearing housing ", which is compellingly related to an identifiable pressure chamber.
   Result: Pressure Equipment Directive does not apply to this group;
   no marking according to Pressure Equipment Directive
   
   
2. Devices with volumes < 0.1 liters and pressure = 200 bar
   - pressure transmitters with back-embedded pressure sensor with an allowable pressure up to 200 bar, e.g. DMP 331, DMP 343, 18.600
   With these devices the pressure sensor is mounted back in relation to the pressure connection. Thus a volume loaded by pressure results in the device. Since it concerns electronic pressure transmitters, the volumes of all these devices are smaller than 0.1 liters.
   To this group of equipment article 3 paragraph 3 of the Pressure Equipment Directive applies: the devices "must be designed and fabricated in agreement with sound engineering practise valid in one of the member states. For sound engineering practise, the abbreviation SEP is also existing Result: the devices must be fabricated in accordance to sound engineering practise (SEP);
   no marking according to Pressure Equipment Directive
   
   
3. Devices with volumes of < 0.1 liters and pressure > 200 bar
   - pressure transmitters with back-embedded pressure sensor with an allowable pressure higher than 200 bar, e.g. DMP 333, DMP 334, DMP 335, 26.600
   According to guideline 1/5 to Pressure Equipment Directive the essential safety requirements of Annex I apply to this group. Concerning the demanded conformity assessment procedure each "module or single combination of modules set out in paragraph 1 of Annex II" can be chosen. Therefore the module A "internal production control" fulfills all respective requirements of the Pressure Equipment Directive.
   Result: essential safety requirements must be fulfilled, the conformity has to be declared by manufacturer ( internal production control);
   marking with CE-sign according to Pressure Equipment Directive
