Electromagnetic compatibility
Instruments in four-wire or Ex-d-ia version are designed for use in an
industrial environment. Nevertheless, electromagnetic interference
from electrical conductors and radiated emissions must be taken into
account, as is usual with class A instruments according to EN 61326-
1. If the instrument is used in a different environment, the electromag-
netic compatibility to other instruments must be ensured by suitable
measures.
2.6 NAMUR recommendations
NAMUR is the automation technology user association in the process
industry in Germany. The published NAMUR recommendations are
accepted as the standard in field instrumentation.
The device fulfils the requirements of the following NAMUR recom-
mendations:
•
NE 21 – Electromagnetic compatibility of equipment
•
NE 53 – Compatibility of field devices and display/adjustment
components
•
NE 107 - Self-monitoring and diagnosis of field devices

2.7 Radio license for Europe
The instrument was tested according to the latest issue of the follow-
ing harmonized standards:
•
EN 302372 - Tank Level Probing Radar
It is hence approved for use inside closed vessels in countries of the
EU.
Use is also approved in EFTA countries, provided the respective
standards have been implemented.
For operation inside of closed vessels, the following conditions must
be fulfilled:
•
The instrument must be permanently mounted on a closed vessel
made of metal, reinforced concrete, or comparable attenuating
materials
•
Flanges, process fittings and mounting accessories must ensure
the microwave impermeability of the vessel and not let the radar
signal escape to the outside
•
If necessary, existing viewing windows in the vessel must be
coated with a microwave impermeable material (e.g. electrically
conductive coating)
