Operating Instructions Flow Limiters SMBM-X and SMBM-V EEX Created on: 16-03-2022 Document no.: 951-180-090-EN Version: Read these instructions before installation or start-up of the product and keep them readily available for consultation.
It can be labeled by the constructor by some kind of designation marking or coding that is preferred for the system. For SKF, this identification is performed by the blue connection cable that belongs to the signal transmitter.
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.
