Safety instructions:
Zone 0
• In the event of potentially explosive vapor/air mixtures, only operate the device under atmospheric
conditions.
– Temperature: –20 to +60 °C
– Pressure: 80 to 110 kPA (0.8 to 1.1 bar)
– Air with normal oxygen content, usually 21 % (V/V)
If no potentially explosive mixtures are present, or if additional protective measures have been
taken, the device may also be operated under non-atmospheric conditions in accordance with the
manufacturer's specifications.
• Associated devices with galvanic isolation between the intrinsically safe and non-intrinsically safe
circuits are preferred.
• If there is a risk of dangerous potential differences within Zone 0 (e.g. through the occurrence of
atmospheric electricity), implement suitable measures for intrinsically safe circuits in Zone 0.
Safety instructions:
Zone division Zone 0, Zone 1
• Version with zone division: Zone division realized by the process connections.
• Versions of process connection:
– Thread
– Flange
• Process connections with thread:
– Thread pitch  0,7
– Thread engagement

5 turns
– Screw-in depth  8 mm
• Ensure gas-tight installation of the process connections.
• After mounting and connecting the probe, it is essential to ensure tightness at the process
connection of IP67.
• Supplied gasket: Suitable for temperature ranges from –50 °C to +200 °C.
• It is the responsibility of the plant operator to ensure sealing in the vicinity of the process connection.
