Product description
Protective measures
Protection IP 65
IP 68 (option for VEGADIF 35, 45 and 51)
Protection class III
CE conformity
VEGADIF 34, VEGADIF 35, VEGADIF 44, VEGADIF 45 and VEGADIF 51 differential pressure
transmitters meet the protective regulations of EMC (89/336/EWG) and NSR (73/23/EWG).
Conformity has been judged acc. to the following standards:
EMC
Emission EN 50 081 - 1
Susceptibility EN 50 082 - 2
NSR EN 61 010
Furthermore VEGADIF 35 is subject to the pressure instrument directive (97/23/EG):
- instruments with max. permissible pressures > 200 bar need the CE mark
- instruments with max. permissible pressures
≤
200 bar do not need the CE mark
NAMUR regulations
Full compliance with the NAMUR regulations NE21, May 1993.
