1.1 General notes
This additional Ex instruction applies to explosion-protected versions of the sensors with the
marking II 1 G. It completes the standard documentation for non-explosion protected versions.
The information given in this instruction contains only the data relevant to explosion protection.
The technical details given in the standard documentation for the non-explosion protected
versions remain unchanged unless they will be excluded or replaced by this instruction.
1.2 EC conformity
The manufacturer declares with the EC declaration of conformity on his own responsibility
conformity with the protection goals of directive 94/9/EC for use in hazardous areas with gas.
Conformity with harmonised standards was checked in accordance with EN 60079-0:2012 and
EN 60079-11:2012.
The EC declaration of conformity is based on the EC type examination certificate of the
Physikalisch Technische Bundesanstalt (PTB):
