VEGAPULS SR 68 • 4 … 20 mA/HART - two-wire

38294-EN-160707

2.5 CE conformity

The device fulfils the legal requirements of the applicable EC guide

lines. By affixing the CE marking, we confirm successful testing of the

product.

You can find the CE Certificate of Conformity in the download section

of our homepage.

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 43 – Signal level for malfunction information from measuring

transducers

•

NE 53 – Compatibility of field devices and display/adjustment

components

•

NE 107 – Self-monitoring and diagnosis of field devices

For further information see www.namur.de.

2.7 Radio license for Europe

The instrument is approved according to EN 302372-1/2 V1.2.1

(2011-02) for use in closed vessels.
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)

•

Manholes and flanges on the vessel must be closed and sealed to

avoid penetration of the radar signal

•

The instrument should be preferably mounted on top of the vessel

with antenna orientation downward
