6.2 Approvals
When radar sensors are used in Ex areas or
on ships, the instruments must be suitable
and approved for the explosion zones and
applications.
The suitability is checked by the approval
authorities and is certified in approval docu-
ments.
Please note the attached approval docu-
ments when using a sensor in Ex area.
Test and approval authorities
VEGAPULS radar sensors are tested and
approved by the following monitoring, test
and approval authorities:
- PTB
(Physikalisch Technische Bundesanstalt -
Physical Technical Approval Authority)
- FM
(Factory Mutual Research)
- ABS
(American Bureau of Shipping)
- LRS
(Lloyds Register of Shipping)
- G L
(German Lloyd)
- CSA
(Canadian Standards Association)
Technical data
Intrinsically safe in Ex environment
Sensors in EEx ia (intrinsically safe) version
require for use in Ex areas special separa-
tors or safety barriers. The separators or
safety barriers provide intrinsically safe (ia)
circuits. Below, a selection of instruments with
which the sensors work reliably. The resist-
ance of the signal cable must not exceed 15
Ω per wire.
Separator and signal conditioning instru-
ment:
- VEGADIS 371 Ex
- A puissance 3 PROFSI 37-24070A
- VEGAMET 614 Ex
- Apparatebau Hundsbach

Pressure-tight encapsulated in Ex area
Sensors in EEx d ia (pressure-tight encapsu-
lated) version can be used in Ex areas with-
out special safety barriers due to their
pressure-tight encapsulated terminal com-
partment (provided the appropriate installa-
tion regulations are observed).
SIL conformity and IEC 61508 /
IEC 61511
VEGAPULS radar sensors meet the require-
ments of functional safety acc. to IEC 61508 /
IEC 61511. For further information see Sup-
plement under „Safety Manual“.
