Special conditions for safe operation
If the medium to be monitored is in zone 0 (category 1G), the unit is installed
such that the cable entry is in zone 1 (2G), e.g. in a boss in tanks, pipes, etc.
Sealing at the transition (category 1/2G) must be rated according to the
conditions of the corresponding application. The part of the sensor housing of
corrosion-resistant steel (316S12) which reaches into the category 1G (zone 0)
has a wall thickness of minimum 0.6 mm due to function. In the application the
user must ensure that in this area risks, e.g. due to aggressive media or
mechanical hazards, are excluded.
