3. Safety
For the use in category 1/2G (EPL Ga/Gb):
The separation (membrane) from the wetted area (category 1) indicates a wall thickness
of less than 0.2 mm which is function-related. In operation, it must be ensured that any
impairment of the separation, e.g. by aggressive media or through mechanical damage, is
eliminated.
The thread of the process connection and the partition wall (membrane of the sensor)
built into a partition wall of the end use application separating an area requiring EPL Ga
from a less hazardous area are made of stainless steel.
The process connection is a gas-tight standardized thread connection with an IP67 rating
according to IEC/EN 60529 between area requiring EPL Ga and the less hazardous area.
The process connection thread shall be self-sealing or sealed by means of sealing
material in the thread or sealed by a gasket.
