Explosion protection marking in accordance with Directive
2014/34/EU
SMBM flow limiters without electrical attachments
The ignition hazard analysis conducted in accordance with EN 80079-36 / -37 found that SKF flow limiters of the series SMBM
without
electrical attachments
do not constitute own potential sources of ignition. They consequently do not fall under the scope of Directive
2014/34/EU and
thus do not bear explosion protection marking. To better incorporate the flow limiters into the operator's explosion
protection concept, these flow limiters have been equipped with an equipotential bonding terminal.
Combination of the SMBM flow limiters with electrical
attachments
Signal transmitter 24-1072-2125
No additional ignition source results from the combination of the flow limiter described with the signal transmitters specified in these
instructions, as it is to be classified as simple electrical equipment in accordance with EN 60079-14, No. 16.4. These flow limiters are also
designated as ATEX flow limiters in the following. See associated classification as simple electrical equipment in accordance with EN
60079-14, No. 16.4, page 2.
Pulse generator 2340-00000091
II 1G Ex ia IIC T6…T1 Ga / II 1D Ex ia IIIC T135 °C Da / -20…+57 °C
3/2 changeover valve 24-1254-3437
II 2G Ex e mb IIC T4 Gb / -20...+70 °C
As a result of the combination of the described flow limiters with the pulse generator/changeover valve specified in these instructions,
these devices thus fall within the application range of the directive 2014/34/EU and are therefore bear an explosion protection marking.
See EU Declaration of Conformity pursuant to ATEX Directive 2014/34/EU, Annex X, page 2.
