Approvals for Marine Applications
The level switch NRS 1-50 in conjunction with level electrodes NRG 16-50S/NRG 16-11S/NRG 16-38S and NRG
16-39S is approved for marine applications.
LVD (Low Voltage Directive) and EMC (Electromagnetic
Compatibility)
The level switch NRS 1-50 meets the requirements of the
Low Voltage Directive 2006/95/EC and the EMC Directive
2004/108/EC.
ATEX (Atmosphère Explosible)
According to the European Directive 94/9/EC the level
switch NRS 1-50 must not be used in potentially ex?plosive
areas.
