Schedule to EU-Type Examination Certificate No. TÜV 99 ATEX 1496 X
(17) Specific Conditions for Use:
1. The permissible temperature range depending on temperature classes resp. on the
maximum surface temperature is to be taken from the operating instructions.
2. A reverse heat flow from the process, e.g. by heat dissipation from components of the
system, beyond the permissible ambient temperature of the filling level sensor is not
permissible. This can be avoided, for example, by suitable thermal insulation of these
components or by mounting the pressure transmitter at a greater distance (cooling
distance).
3. The medium tangent materials of the filling level sensor have to be resistant to the media.
4. For the uses in potentially explosive gas atmospheres and when using plastic floats, the
filling level sensors have to be installed and used in such a way, that electrostatic charging
from operation, maintenance and cleaning is excluded.
For the uses in potentially explosive dust atmospheres and when using plastic floats
process-related electrostatic charges, e.g. due to passing media have to be excluded.
5. When using titanium floats or the Sump Environmental Sensor, the ignition hazard caused
by impact or friction has to be excluded.
6. For EPL Ga/Gb applications the whole device filling level type VISY-Stick ... resp. type
TORRIX Ex has to be mounted in a way that allows an installation that results in a
sufficiently tight joint (IP66 or IP67) or a flameproof joint (IEC 60079-1) in the direction of the
less endangered area.
7. In case of hazards due to pendulum or swinging, the corresponding parts of the level sensor
type VISY-Stick ... resp. type TORRIX Ex... have to be effectively secured against these
hazards.
8. The cable glands for the filling level sensors type TORRIX Exd XT...; TORRIX Exd ...-A;
TORRIX Exd ... Flex and TORRIX Exd ... PL have to be separately assessed and certified
in accordance with EN 60079-0; EN 60079-1 and EN 60079-31. In the end-use application
the degree of protection min. IP6X shall be maintained in accordance with EN 60079-0 and
in compliance with EN 60529.
9. The flameproof joints at type TORRIX Exd... are not intended to be repaired.
(18) Essential Health and Safety Requirements:
No additional ones.
